Small is Beautiful, Get a Small Air Conditioner


There are many types of air conditioners. Some of them are large while others are small. The small ones are more suitable for small rooms. There are advantages and disadvantages of having small units. Also whether you are going to have a small one or a one has to be decided on where are you going to have it and the size of the room. Another factor to consider is the temperature difference between the outside and inside of the room.

The main advantage of the small air conditioner is its low price. Instead of having one large unit you can have a few small ones. The initial cost of the small one is less and the maintenance costs are also less. Most small units do not need professionals to maintain. It is a case of taking the filter away and cleaning. If you have a big one, it is not easy to clean its ducts. These are jobs for professionals.

Another advantage of having small ones is that in case there is a break down only one room is affected. If it is a big central unit the entire house will get affected. In case of a small one when the repairman takes it away for repair he will probably fix a temporary one until the repaired one is brought back. When a big air conditioner breaks down you need to wait until the repair is complete.

The disadvantages of the small units are few. One is that the efficiency of small one is less than that of a big one. Maintenance too is more frequent with a small one compared to a big air conditioner. Normally break downs are also more frequent with the small units. Still it is good to have a few small ones rather than one big one.

The Trouble With Black Mold In Air Conditioners - And What To Do About It


Both AC units and air ducts make great places for mold to hang out.

With AC units, water leaks out of them and makes a nice place for mold. In these water pools mold grows, and then their spores are passed along through the ducts to every part of the house.

Your heating and cooling system also can suck air out of different parts of the house. This means that mold can be passed all over the place, every which way, by your ventilation system.

The HVAC unit that sits outside your home is perfect for mold, because there's always water around it. Mold often grows in the unit's water pools. The evaporator coil is also a major trouble spot.

How Can You Tell?

First, there are the regular mold symptoms which usually resemble sinus trouble; runny nose, stuffy nose, and sinus headache. If you can smell mold when you turn on or run the AC, you definitely have a mold problem there.

To make sure, you can always get a home testing kit from your hardware store. This might be a good idea anyway, and it can also tell you if the source of your mold troubles is your AC unit.

Take the testing gear and check each room. Check around all the vents. Also, check around the unit itself outside, especially where there is any standing water.

What Can You Do?

If you have mold in your air ducts, it doesn't do much good to clean them. That's not just my opinion; that's what the EPA recommends. If you have mold in your ducts, it's symptomatic of a mold problem elsewhere in the house, and until you address that, you won't make any progress on the mold.

For the AC unit, you have to clean it on a regular basis to keep them mold free. Of course, you have to thoroughly clean up any mold that you find around the unit, or in the little pools of water around it.

In general, keep the fan mode switch on your AC on "auto" mode. If you put it on "on," it will recirculate all that moisture that has collected on the evaporator coil through your house and air conditioning system. You don't want to raise the humidity level of your house; that will cause mold problems all over.

If you are building a home or buying a new AC unit, look for one that has options to control the humidity. Some have variable speeds, or different modes like "moisture removal." This will help greatly in controlling your house's mold.

Another tip on picking an AC unit is that bigger machines usually increase humidity. For some reason, people generally choose oversized AC units for their homes. This is actually not a wise choice, because a bigger unit will create more moisture and circulate that moisture through your home.

If your heating and cooling system is infested with mold, you will probably have to call a professional and have the whole house tested and remediated.

Things to Know About Heating and Air Conditioning Units


There are a lot of heating and air conditioning units to choose from these days. Trane, Carrier, Rheem, York, Lennox, Goodman, and Payne are just a few of them to mention. They are all coming out with scroll compressors, variable speed blower motors, and of course high efficient units. They all have different warranties on the condensing coils, compressors, and parts and labor. You would have to check with the manufacturer for their warranty and procedure for getting repairs done when facing an issue with your system.

During the warranty period you may have to keep records from a qualified service company on preventative maintenance performed on your heating and air conditioning units. You can easily keep that record by taping it to the air handler or unit with dates of each performed maintenance. It is always a good idea to perform preventative maintenance on your system because some companies will not honor the replacement of a warranty part if the part had failed due to lack of proper maintenance. So always check with your installing contractor about your warranty coverage and requirements.

The internet is a good place to start locating information on heating and air conditioning units. All of your name brand manufacturers have web sites with information on how long their warranties last. Some web sites will also tell you which system has the most problems and up-to-date information on rebates or recalls. Not all manufacturers have the same problems.

As the saying goes, just because it is new does not mean it is not going to break down. Be proactive by maintaining your system right from the start with scheduled preventative maintenance. It is the best way to ensure your system runs at its best.

Keep Your Central Air Conditioning Working in Top Condition by Easily Cleaning the Condenser Unit


When people think of central air conditioning they think of a nice cool room and the big box with the fan beside the house. Unfortunately, that typically is as far as it goes. Often overlooked is that the outside condenser unit needs a little TLC from time-to-time to work with optimum efficiency. Take the time to maintain your unit and be rewarded with lower electricity bills and no repair bill!

Safety is most important when dealing with your unit. The condenser and fan are powered by 240 volt connections that can be extremely dangerous if left on while servicing your unit. The unit typically has a breaker box located nearby on the outside wall. Open this box and turn it off. Also, turn off the breaker in your main electrical box that supplies power to the unit.

Once the power is off, you will need to remove the protective grill around the unit. This usually attaches by a few screws or nuts. Once removed, gently vacuum the fins using the bristle brush attachment on a vacuum cleaner. Be sure to go over the entire outer surface. The debris stuck between the fins reduces the efficiency of the unit and should be removed as completely as possible.

Next, undo the screws so that the top grill and fan unit can be removed. Be careful not to damage the wires going to the fan. Scoop out any debris at the bottom of the unit and then vacuum the fin surfaces inside the condenser unit. At this point, you may find debris that is stubborn and will not vacuum out.

To address this issue, cover the condenser and electrical connection with plastic and break out your garden hose. Attach a trigger nozzle and spray the fins from the inside of the unit. Start with a diffuse spray and tighten up to a more concentrated spray gradually. It is possible to bend the fins over so use only as much water pressure as needed to dislodge the debris.

The next step is to clean off the fan blade edges. This will help reduce fan noise and improve efficiency.

Next, oil the fan motor as indicated in your owners manual and reassemble the unit.

Finally, cut back any foliage that might be growing onto or near the unit and then turn the power back on. The plant matter is removed to increase air flow to the unit and keep it working at peak efficiency.

Now drink a cold beverage in your cool home. You deserve it!

Ducted (HVAC) Air Conditioning Essential Maintenance Schedule For Homeowners


Ducted air conditions require very little maintenance. Below are the few things you need to do in regards to regular maintenance for your ducted reverse cycle air conditioner.

The return air grille is the big grille (usually located in the hallway). It needs to be cleaned about every 6 months (or sooner if it gets dirty quickly). Some controller's will display a filter on the screen every 6 months or so to remind you of this.

To clean the filter you need to pull back the clips or turn a screw and the grille should pivot down. Then you can vacuum the filter whilst still in the grille or you can remove the filter and either vacuum or clean with soapy water. If you clean with soapy water, remember to not dry in the sun as this will cause the filter to warp.

Once cleaned the filter will not need to be cleaned again for around 6 months. However,if the return air grille of your air conditioner becomes noisier than usual, or the air conditioner cools/heats less than normal it is a good sign that the filter needs a clean.

The outdoor part of the air-conditioning unit is largely maintenance free. You will notice water dripping from the drains of the system but this is a sign that the air-conditioner is running correctly. Keep the fans clear of debris and sticks and consider applying a spray or film on the outdoor unit to slow down rust if you live in a coastal area. Before applying any chemical however you should check with the manufacturer.

Other than this your air conditioning system is maintenance free. As a precaution it is advisable however to have someone inspect the system every 4 to 5 years to check for any major wear and tear.

Ductless Split Heat Pump Review - Ductless Heating and Cooling of the Hard to Duct Home


You are building a log home or a home that you want the rustic look of the floors above also being the ceiling of the floor below. You hate the thought of having to install ugly heating and air conditioning ductwork in your new home. For you there is hope. You can still have a comfortable home and have the look that you want.

The advancements in ductless heating and cooling has made it possible for you to have those wood ceilings, roof lines, wood walls, and everything you can think of. The new ductless units take up very little space on your wall. They can be placed almost anywhere with a little planning, and they are very efficient at both heating and cooling.

The many features do not stop with the heating and cooling. Most units have remote controls to run the unit. Many of these units can run multiple inside units from one outdoor unit. These units are so quiet that you have to feel the air coming from them to see if they are running. The installation has been simplified to the point that they can be installed very quickly by an experienced professional.

If you are concerned about the looks on the outside, that too can be fixed rather easily. The piping and wiring going to the indoor units is relatively small and can be hidden in many ways by using a little imagination. Colored aluminum can be fabricated to cover the pipes. I have also run the piping through rain spouting and made it to look like just another rain spout coming off of the roof.

If you are looking to build or remodel and are worried about the look you will have on the inside, then take a look at ductless split heat pumps to give the comfort and the looks.

Many heating professionals can find a way to make these units work for you. Make sure that you do not settle for something less than you want. You may need to look at more than a few companies to find the one that will give you the system that you want.

Steps For Installing Flexible Air Conditioning Duct


Flexible air conditionings are used for transferring the air from the duct line to HVAC system. Flex duct is made from aluminum and lines of plastic. The inner layer of this product is surrounded by layer of insulation that is used to protect the barrier of vapor. You need to install each and every layer carefully and you need to follow the procedure of installation properly. If you don't follow it then you won't be able to install them properly. If you want to install it then you need to follow following steps to install your product.

Steps for installing flexible air conditioning duct:

1. Find the distance between the place where you will be placing your flexible duct and the point where you will be connecting it. Use tape to measure the distance. The measures that you get double it and add it to the diameter of your measurement. Then you need to bend your degree up to 90 degree. You need to install your flexible properly.

2. Try to increase the length of your flexible air conditioning duct. You need to make the surface of your flexible smooth. Try to place the stretch tape near the flexible tape. The end of the tape has to be an aligned and try to make the inner of the liner flexible.

3. Try to open the big scissors and try to push the lower blade of the scissor in the flexible duct and try to cut it as per the length of the flexible duct. Ensure that the all the layers of the flexible duct are equal.

4. Try to cut the flexible duct with the help of scissors. Once you have cut the scissors use different types of wires for supporting the inner layer of your flexible air conditioning duct.

5. Try to roll the barriers of the vapor and try to insulate the inner line of the flexible duct from the back of your product. Try to expose 3 inches of the inner line from both the sides of the device.

6. Slide all the liner on both the ends that are found between HVAC system and the register.

7. Place the duct fastening on the each end of the flexible duct. Ensure that the straps are connected with each other and you need to connect with the different point of HVAC system.

8. Tight the plastic strap with the duct fastening. To install it you need to use different tools and the wrap tape to make the plastic duct straps.

9. Once you have installed the flexible then you need to unroll the insulation and you will have to unroll the vapor barrier. Try to cover the inner liner that you have attached with the flexible air conditioning duct. Once you have completed the installation then you can start using the product.

Air Conditioning - How to Keep Your Electricity Bills Low


Are you finding it harder to budget for the amount of money you pay to your electric utility? This is a very common problem since most people have to deal with the rising cost of living on a fixed salary. At the same time, it is very hard to expect oneself and one's family to do without the comfort of an air conditioning unit because weather conditions have made summers too hot to handle and winters far colder than before. Thankfully, there are ways in which you can manage your air conditioner so that your electricity bills do not climb too high.

One of the first things you should do is pay close attention to the weather and set your air conditioning according. The amount of cooling you require during the peak of summer is undoubtedly high but you certainly do not need to cool your house to the same level when the weather cools. In fact, you might not even require air conditioning during some of the days late in the year.

Make sure that the air conditioner you use is placed correctly. Most people recommend placing it on the north side of the house so that it does not have to work too hard to cool the house. You should also use the right sized air conditioning unit for your room or house. A small unit will have to work too hard without giving satisfactory results whereas a very large one will use up a lot of energy.

You have to take care of your air conditioner well so that it works efficiently. This involves cleaning its filter as well as condenser and coils. You can do it on your own if you check the owner's manual. It is also a good idea to get it serviced twice a year.

Most people who have central air conditioning do not realize that they can save quite a bit of money by closing the air vents in rooms that are not occupied. You might have to take a bit of trouble to monitor this but it is certainly worth the effort. Another thing that you could do on really hot days is to close the intake of air from outside so that your air conditioning unit circulates air inside the house. If you do not do this your machine will pulls in hot air which it then has to cool, thereby using too much energy.

If you have a large window that bears the brunt of the sun's rays then you should close it with a blind so that the heat does not enter the house and reduce the cooling effect of your air conditioner. Another thing that you should always do is have the slats of the blinds pointing towards the ceiling and not downwards so that the sun's rays cannot warm the room.

These cooling tips will help you get the most out of your air conditioning system without having to pay too much money in electricity bills.

Selection and Installation - Air Conditioning Unit


When choosing the correct air conditioning for your home, consider various options before making a final decision. There are permanent models, as well as portable air conditioning units that you may use to cool your home. The small window models are easier to install than a large unit, which may require the help of a professional.

If you find yourself without a central air conditioning unit, you could be miserable during the summer months. You can save yourself the misery by installing a small, and very manageable, single room air conditioning unit. Many homeowners choose to install such a unit in their bedroom, but that's completely up to you. You can choose between an air conditioning unit that is removable for your window, or you may opt for a permanent installation in your wall. A portable window unit is the easiest to install and you will be glad to know that you won't have to make any holes in your wall because most units just use a regular electrical outlet.

Before purchasing your window air conditioning unit, measure your window to ensure that you get one that fits perfectly. If possible, choose a window that is already near an outlet as this will save you from having to use extension cords.

Installation Of A Window Air Conditioning Unit

When you've purchased the perfect air conditioning unit, remove it from the box and follow the installation instructions. Your new air conditioning unit should include mounting hardware, which will need to be attached to your window. It's important to read, and follow the instructions carefully. If mounting hardware is installed incorrectly, the air conditioning unit may fall from the window and cause damage to whatever lies in it's path, not to mention the certain damage of the unit itself.

Now, you are ready to place the air conditioning unit into place. Open the window high enough to allow you room to place the unit and also some extra room for your arms to move without hitting the window.

It may be a good idea to have someone help you during this step, in order to hold the window open and to allow you the convenience of an extra pair of hands should the unit be difficult to balance during installation. Your new air conditioning unit should have handles for easy manageability, but it's better to be safe than sorry. Make sure that the air conditioning unit sits properly into the mounting hardware and then close the window onto the air conditioner. Pull out the extensions, which should be located on the side of the unit, in order to close the openings between the unit and each side of the window. Once everything is in place, secure each extension to the sash according to the instructions.

Before wrapping up, look for a foam strip that should be included with your air conditioning unit. This product is used to fill the air gap in the window. As you finalize the installation, make sure that the air conditioning unit is secured in position using it's mounting brackets and plug in the unit once you have completed every step as outlined in the owner's manual.

It's important to realize that each unit may be different and, therefore, each may have small variations in installation. By reading your owner's and installation manual carefully, you will ensure a quick and easy installation. A window air conditioning unit should take 1-2 hours to install and is a recommended do-it-yourself project.

Repair Of An Installation Air Conditioning Unit

If your new air conditioning system is not functioning properly, unplug it immediately. Begin by reading through the troubleshooting section of your owner's manual. If your system is under warranty, call the manufacturer, whose name and contact number should be listed in the manual. If the system is no longer covered under any kind of warranty, you may wish to call an air conditioning professional or simply replace the unit altogether. It is often more expensive to pay for repairs of an item than it would be to purchase a completely new air conditioning unit.

Mini Split System Air Conditioner - 10 Advantages Of Ductless Mini Splits Over Conventional AC Units


Mini split system air conditioner technology was first introduced in Japan out of a need for smaller and more energy efficient air conditioning. When reducing your electricity bill by hundreds of dollars per month is your high priority you will want to read this article. The advantages of air conditioner split system are: Security, Noise, No floor space taken up, No big holes, No ducts, No heat losses, Multiple design options, Easy outside placement, Government subsidies, and Lower utility bills. After you have checked out these ten advantages, you should be in a better position to decide whether a mini split system air conditioner installation is worth looking into.

No security issues

With split air conditioner system, there are no security questions as with the portable air conditioners, where the venting hoses require a less-than-secure installation into the open window.

Noise is reduced and removed from the room

With the ductless mini split systems the most noisy, compressor unit is relegated outside of the room. Thus, the major contributor to the air conditioning noise is removed. It turns out that the inside unit, the evaporator, can be run much more quietly. Sometimes, the blowing fans will be the loudest noise you will hear from a split air conditioner system.

Slim line models take no floor space

The inside unit of a mini split system can be designed to be very slim and will take no floor space.

There is no need to create big holes in windows or walls

The only connecting hole to the outside is a 2-3 inch hole in the wall on the back of the inside mini split unit. There are absolutely no security concerns with that either.

No need to install any ducts

Compared with ducted, central air conditioners, there are no ducts here. Just the narrow conduit to connect the inside and the outside unit.

No energy losses in ducts

As there are no ducts, there are no duct heat losses either.

Flexibility in interior design options

The interior unit of a mini split system can be installed below the ceiling or above the windows. Some designs will allow for the bottom of the wall, or floor installation of a split unit as well.

Flexibility in exterior unit placement

The exterior, compressor unit can be as far as 50 ft. away, and in some cases even as far as 100 ft. away from the interior, evaporator unit.

Government tax credits on mini split systems

In the US, mini split systems qualify for government tax credits up to $1,500.

Utility bill savings

While the US tax credit savings come and go as the law changes, the energy savings on electricity bills are here to stay. When you are judiciously using mini split air conditioning system in your house, you can save hundreds of dollars each month.

Air Conditioning Repair - Essential for Your AC Unit


If you are serious about extending the life of your air conditioning unit, then, there is no getting away from regular air conditioning service. The air conditioner, just like any other electronic device, is vulnerable to functional and operational problems. Over the course of time, elements within the unit could break down. As a result, the unit begins to lose efficiency. In some cases, the unit may stop functioning altogether. In such instances, you need the services of a reputed air conditioning repair service.

Typically, most consumers arrange for periodic check-ups to ensure that everything is in working order. A spring and fall check-up should suffice. Minor problems do crop up from time to time, more so when the unit becomes old. However, these issues can be taken care of quickly and without much cost if they are identified early on.

Some of the recurring activities performed by service personnel include:

- Cleaning filters: Removing debris and dust from the unit involves more than just looking at the interior pads. It is necessary to inspect the ducts and vents too. This protects the entire system from all the potential problems that could arise. Clogs should be flushed so as to prevent blockages. When vents are cleaned thoroughly, efficiency also rises. Along with this, it is necessary to clean the area surrounding the unit.

- Tuning up: Regular tune-ups ensure that the unit is working at optimum capacity and delivering the right output. Tune-ups generally include measurement of airflow, making adjustments in refrigerant charge, testing the performance of the capacitor, checking levels of Freon and so on. All the coils and wires are also inspected for rust, wear and tear. Following a proper tune-up, the air conditioning unit becomes re-energized and it starts to work at its optimal capacity.

While some people leave off repairs until problems arise, others invest in regular maintenance. Repair must be performed by trained professionals who have the following skills:

- Preventative maintenance
- Diagnosing and fixing problems with heating and cooling systems
- Replacement of parts
- Regular tuning up of units
- Unit control adjustments
- Onsite evaluation

It is necessary to hire trained professionals. Working with electrical appliances is dangerous. For example, as far as the AC unit is concerned, mixing Freon with electricity could have dangerous repercussions. Having a trained professional on the job ensures safety as well as quality work.

When it is time to hire service professionals, some care must be taken to find the best company for the job. There are different options and the customer has the freedom to choose between different options.

How to Install a Duct Fan to Lower Heating and Air Conditioning Bills


What is a duct fan. It is a fan that is placed in the ductwork in your home to move air from one part of the house to another. Why did we add a duct fan inside the ductwork in our home? It is because we have a second floor that includes an office, a bathroom and what we call the craft room. Our air conditioner unit just could not get enough air to the upstairs. During the summer months, it was always too hot and during the winter months it was always too cold.

The new HVAC system we had installed in our home last year was supposed to be large enough to heat and cool the entire house. The problem turned out that when the house was built, the initial contractor made some glaring mistakes.

We had ducts that did not go anywhere and/or were not sized correctly for the air flow required. When the new air conditioner was put in, that was all fixed except for the duct going to the second floor.

We weighed our options and decided to put in a duct fan and here is how I installed it.

I cut open the supply duct before it went into a supply distribution box. The distribution box supplied our upstairs registers. Our duct was 12 inches, so inserting a 12 inch fan was not a big deal.

I then cut into the flex duct and pulled the Mylar and fiberglass material back.

I checked for the air flow direction arrow on the side of the fan to make sure I did not have the fan facing the wrong direction. Then I inserted the it.

The duct fan itself is just a hard galvanized metal tube with the fan mounted in it and two wires hanging out through a plastic grommet. I mounted a standard metal electrical box to the side of the fan housing that will allow me to connect all wiring in a protected enclosure. I really hate to see wires loose and just connected together. Also, the National Electrical Code requires it.

The next step is to reattach the supply duct to the fan. Once again slide the Mylar liner over the outside of the fan housing and tape it using Foil Sealant tape, mastic tape or butyl tape. All these tapes are a metal faced tape with a soft foam lining to seal the tape to the duct. It is really sticky stuff and it works great! Make sure you seal everything as you do not want any air leaks.

Then cover the entire assembly with more duct insulation to keep all air passing through the ducts and not leaking out. If any air leaks out, you can have condensation on the outside of the fan housing. This water can drip down and ruin your ceiling. I use foil tape with a fiberglass reinforced lining. I also use a foil tape for sealing joints and seams against moisture and vapor on foil jacket insulation.

Never use the gray cloth tape as it is not rated for this type of usage.

After the electrical work is completed, the last remaining piece of insulation will be sealed around the fan.

As a temporary measure to see if everything worked, I wired the fan motor to an extension cord and plugged it in. Immediately, there was cool air in the office area. Within the hour, the temperature was the same on both floors.

Now, to make it permanent, I installed a 4x4 electrical box. It was equipped with an auto/manual override switch and a variable speed motor control.

An air pressure switch was installed in the riser duct to automatically turn the fan on or off when the air conditioning unit turns on and off downstairs. The objective is to have fully automatic action with minimal electrical usage.

The total cost to install the duct fan and the controls were less than $200.

Hydronic Heating: An Ideal Solution for Your Home


There is no denying that hydronic heating has seen a spike in interest over the last few years. This heating system allows water that has been heated to be pushed through pipes in the home, providing warmth throughout the home. Sometimes called a forced air heating system, this setup is designed to be an option that is better for the environment.

One thing you will find with the use of hydronic heating panels is the fact that they will reduce your energy consumption in the home. This reduction in non-renewable energy is going to reduce your power bills while reducing your carbon footprint. This of course makes it a greener solution for your home.

Of course, the type of power you choose to fuel this system can also be adjusted. While some people may have access to things like natural gas, petroleum or even solar power, others may have access to the power company. No matter what power source you have, you are going to discover that there are available options for any type of hydronic heating systems you may be interested in. It will be important to consider all your options to determine the system that will best suit your needs.

Another benefit many people experience with this type of heating is that their home is going to be significantly quieter. Most homeowners who use the system have reported a noticeable reduction in noise levels and that creates a peaceful living environment. Best of all, you do still experience all the same warmth that you would expect from a traditional heater.

Those suffering from allergies are going to find that this heating system will also be a great choice for them. Unlike traditional heating solutions, there is a reduction in the amount of dust and an increase in moisture both of which can help to address some concerns you may have. Instead, the air circulation provided keeps the air cleaner, while bringing in natural moisture that will aid in the prevention of dry skin.

It will be a good idea to do your shopping in advance before you choose to install any of these hydronic heating panels though. There are quite a few companies who offer these systems and it will be important that you look at more than just the cost that is associated with them. You'll need to pay close attention to the features offered that can have an impact on the experience you may have, along with the amount of area that the system will heat.

When you prepare for this venture, just understand that the process is going to take time. Not only will there need to be an underground system installed, but there will also need to be alterations done to the ventilation system in your home. However, once it has been installed, you will have a system in place that will require little maintenance, while offering you effective heating at a reduced cost.

Portable Air Conditioning Units - Advantages of Portable Air Conditioning


Air conditioner is a great necessity in summer climate that is hot and humid. In these weather conditions, cool air from the air conditioner unit takes all the tiredness away from the body and helps in rejuvenating it. It is very important to keep the portable air conditioning units clean in order to maintain the effectiveness of cooling. Basically, portable air conditioner units can be transferred from one room to another without much manual labor.

This helps in ensuring that all the rooms of close vicinity can be cooled at once. This is an excellent way of managing the room temperature of a household or a single floor with various rooms. These units are portable and can be taken to any place; this mobile nature of portable cooling units is a plus point that is missing in wall mounted units such as window, split and cassette duct air conditioners.

These portable units are easy to maintain and clean that is the plus point of this cooling unit in comparison of wall mounted air conditioners that are serviced once in a year. In terms of spacing, these potable units do not take much space and can be adjusted in any room without much hassle.

In order to install portable air conditioning units, you do not need to make an extra provision such as cutting the wall in order to fix the air conditioner. Thus, they are more useful than the regular air conditioner units in terms of its use. Even in cost factor, these units are not higher than the usual cooling units and can be installed in any nook and corner without any difficulty.

Finally, if you are planning an air conditioner for your house or office, try portable cooling units that are more efficient than the usual air conditioners.

Three Business Ideas For Beginners


I want to discuss some business ideas for beginners that are available for you to easily generate profits. If you are looking for some ideas that have much profit potential and are available to create a business this is the article you must read. It is important when first starting your business to have some ideas on what you actually want to achieve. Some people already have an idea of what they want to do, but many that want their own business have no ideas on what is profitable and what will be easier for them to complete. So let's discuss some business ideas for beginners right now.

Air Conditioning Repair

This is a great business idea for beginners especially if you have the skills and knowledge to repair air conditioners on a consistent basis. Stop working for your boss and let your skills help you to create your own business. The great thing about this business is the start-up costs are very low because all you need is the right tools to repair these appliances. The crucial thing is to build a customer base that you will have access to. Just before you leave your job you will want to tell customers about your new business and tell them why they should use yours rather than anybody else. This will be a good time to present your business model to potential customers. This is obviously a good business during the hot summer months and in hot areas that need air conditioning.

Boat Cleaning Service

Do you like cleaning different things but don't want to actually clean up someone's home or office? Then maybe you should try starting a boat cleaning service that provides professional cleaning to any type of boat. Boats get pretty dirty and rusty when left in the salt water for a long time and it can be a great help to many if you would clean them. If you live in the right area such as on the coast where boating is popular, then you have a great chance of starting a very successful business. The competition is also very low and is wide open for any entrepreneur to take advantage of this sector. This was just another great business idea for beginners that you can use.

Carpet Cleaning Service

Carpets are placed everywhere from residential to commercial buildings and it really is a pain to clean carpets if you don't have the right equipment. Most people don't have time to clean their home and carpets and that is why they need a carpet cleaning service to hire. Commercial businesses are great as well because the profit potential here can be enormous if you pick the right places. As long as people are buying carpets there will always be a need for a carpet cleaning service. Try spreading the word about your business through different venues such as family, friends, neighbors, newspaper ads, and many more to get the word out about your new business. The startup costs are a little expensive because you will need different equipment to get out really tough and dried on stains.

These are some business ideas for beginners that can be implemented right away with some motivation and ambition.

What to Look for in an HVAC Service Agreement


As a homeowner, you are probably very mindful about how well your house operates. You check the paint for cracks and peeling, you listen out for odd noises and flickering light bulbs, and you keep track of all warranties on electronics and appliances. When it comes to your heating and cooling, you want to make sure everything functions properly regardless of the season. If you've considered working with a local HVAC company to handle regular repairs and inspections, you may be offered a service agreement for long-term maintenance.

A service agreement with a heating and air company typically involves a number of perks one might not receive through contacting a company when something breaks. Preventative maintenance is one benefit to a service agreement, in that the technicians inspect your systems and head of potential problems so you don't pay more for repairs.

If you have been offered such an agreement, you might wonder if the service you get is worth the cost. Agreements will vary depending on the company, but there are a number of commonalities that should belong in every agreement. Some things you want to watch for include:

1) Priority Status. It can be frustrating call on an HVAC repairman and get the "we'll come when we come" answer. A service agreement should include some provision for priority calls when you have an emergency.

2) Discounts on Needed Parts. If something in your heating system needs a new part, the cost is normally tacked on to your bill. Priority customers should be given a discount option with a service agreement, or at least a discount on that specific repair or installation.

3) Thorough inspection of AC units. It's always good to make sure your air conditioning is ready for a hot summer. Have your technician check the freon and condensor, clean filters and drain lines, and make sure the temperature gauge is accurate.

4) Thorough inspection of your heating system. Again, an agreement should guarantee your HVAC serviceman will pay detailed attention to your furnace or boiler. Duct work, charges, burner assemblies, and evaporator coils should be inspected, cleaned, and repaired where needed.

Before you commit to signing anything, however, it's best to comparison shop if you intend to invest in long-term service. An agreement with a reputable company is beneficial to homeowners concerned about comfort and safety, but you don't want to get roped into a water-tight contract that doesn't benefit you. Shop around.

Mini Split AC Units - Three Types of Split Units For Your Home


Mini split AC units are becoming very popular as a type of ductless air conditioning that allows a significant reduction of the home cooling costs thanks to an individual room inside unit thermostats, and efficient, ductless heat transfer. In this article you will review three types of split ductless AC units: Wall mounted mini splits, Ceiling recessed mini splits, and Ceiling suspended mini splits. Reviews will compare and contrast these three types of split units.

Mini split AC units are based on the idea of separating the refrigerant compressor or condenser part of the air conditioning unit into the outside unit, and keeping only the expander, or the evaporator, cooling part of the air conditioning unit inside the room. Then, using a relatively thin, a few inches in diameter, conduit with insulated hoses for the incoming and outgoing refrigerant liquid, the heat is efficiently transported from the inside of the house and deposited outside. Such a configuration significantly reduces the noise inside the house. The split units, when positioned right, also provide a quick and completely controlled way to cool down targeted spaces in a home. And finally, they can be a savior when someone is searching for a "no window air conditioner" for a single room.

Let's look at the three types of mini split AC units. You should have a better idea which one might be best suited for your home when you are done reading. We will not discuss the split AC units condenser part here, but instead focus on the split AC units evaporator unit, or the inside unit.

Wall mounted mini splits

These are the most common type. The installer will first drill a small 2-3 inch hole into the interior wall and provide the conduit and the hoses. He will then connect the inside unit to the conduit and the hoses and mount the inside unit over the hole. Usually, the wall mounted split unit will be mounted either above the window or relatively high up on the wall to provide sufficient air supply. The advantage of wall mounted split unit is the ease of installation. The disadvantage is limited air flow.

Ceiling recessed mini splits

Ceiling recessed mini splits will mount inside the ceiling, so none of the unit will protrude out of the ceiling. However, a significant amount of depth will need to be provided for the recessed part, as much as 7 - 10 inches or more. The ceiling recessed split units that are available on the market place will normally take up the air centrally and blow it in four different directions through the directed vents. The advantage of ceiling recessed split unit is that a larger unit can be accommodated into the ceiling given enough space there. The disadvantage is a peculiarly fashioned air flow, taking in air centrally.

Ceiling suspended mini splits

These are suspended several inches from the ceiling on two or more metal rods. The air flow will be uni-directional, from the front to the back of the unit. Due to the adjustable suspension, the unit can be significantly removed from the ceiling which plays a role when the ceilings are high. An additional advantage of ceiling suspended split AC unit is that they are extremely "aerodynamic", meaning that the cold and hot air flow around the unit will be completely unobstructed. In contrast, the ceiling recessed split unit air flow is obstructed by the ceiling and the wall mounted split unit has the air flow obstructed by the wall. This is significant as a better air flow around the unit means that the cooled air can reach a longer distance, thereby more effectively cooling larger spaces.

The Importance of Air Conditioning Maintenance


If you own a central air conditioning unit, it is important to perform regular maintenance on it. This is something many homeowners neglect to do, often resulting in high repair bills. Many people see repairs as useless or a waste of money. In fact, the complete opposite is true; if you perform regular maintenance, you might be able to save money on future repair bills.

Higher Utility Bills

When your air conditioner does not run efficiently, you will have much higher utility bills than is necessary. The harder your unit has to work, the harder it is on the air conditioner and on your utility bills. If you start to notice your utility bills are higher than normal, this could be a sign your AC needs maintenance or repair.

Filters

The air filter is often a major culprit in an inefficient air conditioner. If you do not regularly change your filter, it has to work harder to get through the dirt and debris that has collected on the filter. Most filters need to be replaced every one or two months unless you purchase a higher quality filter or one that filters out special allergens. If this is the case, you should follow the directions of the manufacturer to ensure your unit runs properly.

Clear the Area Outdoors

Periodically check the area around your air conditioning unit. Any large weeds or collection of leaves can obstruct the air flow coming from your AC unit. Take extra care to determine no leaves or weeds are stuck in the coil because this is what causes the air to run inefficiently. Once you are sure the area is clear, you can also clean the air outlet on the front of the unit to ensure air flows freely.

Check for Rust

An air conditioning unit that is full of rust will not work as efficiently as it should either. Sometimes you can take care of the rust on your own with a steel paint. If the rust spots are large or you feel the rust is affecting how your unit runs, it is best to call for professional service to ensure your unit is still safe to use.

Regular maintenance on your air conditioning unit is important to its effectiveness and longevity. It only takes a short amount of time to change the filter, inspect the unit, both inside and outside, and clear away any debris. These simple actions could save you hundreds of dollars in the long run.

Knowing the Truth About Air Conditioning Prices


Air conditioning prices are always guaranteed to become a major source of conflict and controversy within a household, for it would seem that every single consumer on this planet has an opinion as to what they perceive to be the grossly unfair and avaricious prices charged for air conditioning units.

The simple truth of the matter is this: air conditioning units is a fiercely competitive market with no shortage of providers or products and so this means that the consumer will be guaranteed to find an air conditioning product that matches their requirements and expectations. Of course, the trade off here is that the consumer will actually need to ensure that they compare the different products on offer so as to find the most suitable product for them.

With that in mind, it is worth noting that making a final decision based solely on the air conditioning prices is not a sensible approach and the reason for this is that the price tag will provide the consumer with a limited amount of information. It is

It is important to appreciate that the value of the prices extends beyond merely the numerical value specified on the price tag of the unit in question, and so the consumer will need to consider and factor in running costs and overheads as well. After all, any and all air conditioning units will by virtue of their design, require electricity to operate and function properly and so the consumer must factor this in the equation.

Related to this is the Energy Efficiency Rating of the unit and this particular value will be of particular interest to the consumer because it is the value that will determine how much the consumer is liable for in energy consumption. In essence then, the more energy efficient the unit is, then the less energy that will be wasted and therefore consumed. Therefore, you may find that paying a little extra for initial prices will net you far better results and savings than opting for a cheaper model.

Make sure that you get a clear and transparent breakdown of air conditioning prices. Specifically, particular interest should be given as to the services and extra features that are included (if indeed they are).Does the sales price as stated include a warranty and or installation, or will the consumer be required to pay extra for these?

If they are required to pay extra, then what will be the cost?

Again, the expense of installation and warranty is always a serious bone of contention for consumers, but these are essential things to have indeed. The last thing you want is for an incorrectly performed installation procedure performed by yourself then causing the delicate components of the unit to then become severely damaged.

Likewise, the warranty will cover you in the event that the work is shoddy, or the air conditioning unit suffers damage through no fault of your own negligence. Be smart with air conditioning prices, not stingy.

Air Conditioning Systems - How it All Works


Central air conditioning systems are the largest and most complicated of all air-conditioning systems. Because of this, it is mainly used in large buildings such as apartment complexes and office buildings. The reason why this type of air-conditioning is used instead of window units or portable air conditioning units is because they are more economical to run in the long run. Window units are generally only good for small rooms and are not practical for cooling large areas.

Central air units are a set of machines and parts that work in unison to cool air. Generally a separate space such as a small room will be needed to install this system. This type of air conditioners consists of four different parts or systems. They are the compressor, which will be larger than ordinary air conditioner compressors, condenser, evaporator and the thermostatic expansion valve. If these parts sound familiar it is because they are also found in refrigerators, the main difference being that they will be bigger. There are basically two different types of central air conditioning units. The direct expansion system also known as the DX system and the chilled water system are the 2 basic types.

The DX system will use a big compressor and condenser which will be installed in one room and the cooling coil and evaporator will be installed in another room. The chilled air is then distributed via air ducts to different rooms. This system is used in smaller buildings and is the more common of the two types. The chilled water system is housed in one room and uses a sophisticated system using brine solution to cool the air. The system is more noisy and complicated to run which means it needs qualified technicians to keep it running smoothly. Chilled water systems are used for large buildings. The biggest advantage a chilled system has is that if there is leak in the pipe only water is lost and not expensive refrigerant.

As far as DX central air conditioners go, there are a number of players in the market today such as, Whirlpool, Samsung, LG, GE and so on. They all have their websites which makes it easy to find prices and size. As far Chilled water systems go, there are only a few manufacturers that make them. The reason for this is because they are more complicated and expensive to make. Some of the companies that make this type of system are GE and Westinghouse.

Split AC Units


The distinct advantage of a split AC unit is that it may be used to cool a room during summer season and also to heat a room during winter. This means that split air condition units are not such an item which are used in one season and have no use in other season. The size of a split AC unit is generally small as compared to a conventional window air conditioner. Normally, a split aircon unit has been designed to regulate the temperature of an area of 400 square feet. Nevertheless with the recent advances in technology, such split AC units have been invented which can serve the purpose for larger areas. The great thing with these is that they do not make use of much power.

The cooling capacity of the split air conditions unit is a significant aspect and is measured in terms of tones. This actually refers to the total ability to cool. The energy efficiency ratio value makes a comparison between the cooling efficiency of the split air conditioner to the quantity of power which the unit uses. This means that the machines with higher EERs will ultimately save more power.

The split unit can also eliminate moisture from the room while it cools the air. The removal of moisture is measured in liters/hour. This feature is also very crucial since it reduces the humidity of the room. This is the major reason why split AC units are mostly used in humid regions as opposed to air coolers which are preferred mainly in drier regions.

Installing a split AC unit is generally not a tough ask since it comes with a line set which is used to join its indoor components with its outdoor components. They have fully charged coolants with them and thus there is no need of any chemicals or refrigerants to be added while installation.

Ceres Living MLM Review - AC-11 DNA Repair and Skin Care As Best Treatment For Sun Damaged Skin


When it comes to investigating the merits of a health and wellness product, one of the most important criteria that you should always consider is that one main ingredient that is unusually uncommon that has remarkable healing properties that is backed by research and science statistics. You have probably heard about the remarkable benefits of acai berries and Echinacea. That was the rage for the past four years and still is today. Have you heard of an ingredient called AC-11? A health and wellness stem cell drink called AIO Premium Cellular Health, manufactured by Ceres Living MLM company, contains that key ingredient.

What Is AC-11 And How Does It Help With DNA Repair?

AC-11, also known as Uncaria Tomentosa (or Cat's Claw) is a vine that is grown in the tropical regions of South America. The bark of these vines are being extracted for medical use. There are studies that already has proven that this remarkable ingredient can slow the aging process.

Many age-related diseases have been attributed to DNA cell damage that result from toxins that we are constantly exposed to in our toxic environment ranging from cigarette smoking, the foods we consume, pollution, carbon dioxide, air-borne viruses, and even the harsh rays of sunlight. As the human body is constantly stressed daily, this causes the body to be susceptible to free radicals that contribute to inflammation and other potentially cancer causing carcinogens.

There is also compelling evidence that strongly suggest that neuro-degenerative diseases that plague the aging population is also attributed to the gradual decline of DNA anatomy. Commonly known as Alzheimer's Disease, this aging disease can best be described as the constant abuse our bodies take from our constant exposure to environmental toxins that damage our DNA.

How Does AC-11 Help With Anti-Aging Skin Care?

DNA doesn't only play a crucial role in our anatomy. It also is a major factor on one of our body's largest organ: the skin. The foods we consume are loaded with toxins despite how healthy we try to eat. Although a person who consumes healthy foods are less likely to be subjected to DNA damage on a grander scale, it is not possible to cover all the gaps through healthy nutrition. This is where health and wellness ingredients and formulas can come to the rescue.

Our skin is constantly being exposed to the harsh sun rays regardless of how much sun block is applied to our skin. Every time our skin is exposed to the sun, it still becomes incredibly vulnerable to cellular damage. And that can have an impact on the DNA component of the cell. It has already been revealed that DNA damage is one of the primary causes of aging attributed to sun damaged skin.

AC-11 can also be taken as an antioxidant supplement to strengthen the body's immune system. Immune system function is also crucial for the stability of DNA replication. Healthy DNA must be duplicated properly for DNA maintenance on a deep cellular level. This will eventually have a positive outcome on the appearance of your skin by diminishing signs of wrinkles through DNA preservation through consumption of AC-11.

Information About Types of Air Conditioning Systems


There are several types of air conditioning systems. The application of a specific sort of system task depends upon a variety of factors like how long the location is to be cooled, the overall heat generated inside the enclosed location. The HVAC (Heating Ventilation Air Conditioning System) designer only consider the parameters and suggestions. Types of air conditioning service area:


  • Window

  • Split

  • Packaged

  • Central

Window Air Conditioner

Window type is a very famous and most commonly using type. It is very cheap type of air conditioner. It can fit in the bedroom, personal room, or hall. Window system is used to fit all type spaces. If you fit a cooling system, then you need not to open your windows. These types are comprised of components like the condenser, compressor, expansion coil or expansion coil and evaporator of the cooling coil, all housed in a single box. If your house or room size is less than 100 sq feet. A window air conditioning service of about 0.8 ton can be good enough. If the size of office room is more than this but less than 200 sq feet.

Split Air Conditioner

Split types are used for tiny rooms and halls, usually in place where window types cannot be installed.The split type can be installed in your house or office where you don't want to disturb the setup of the room and avoid demolitions in your favorite space. There are two main types of the split air conditioner.

Outdoor unit - This unit houses major component of the air types just like the compressor, condenser coil and conjointly the enlargement coil or capillary tubing. This unit is installed outside the personal rooms or bedroom space which is to be cooled. The compressor is the increase noise making the type of the air conditioner, and since at intervals the split air conditioner, it is placed outside the home.

Indoor unit - It is the indoor unit that produces the cooling effect inside the personal room or the office. This is a wonderful looking tall unit usually white in color, though these days a number of stylish types of the indoor unit are being launched.

Packaged Air Conditioner

The window and split types are usually used for the tiny air conditioning service capacities up to five tons. The central air conditioning service is used for cooling loads extend beyond twenty tons. The packaged types are used for the cooling method in between these two extremes. The packaged air conditioners are obtainable within the fixed rate capacities of three, five, seven, ten and fifteen ton.

Central Air Conditioner

The central types plant or systems are used when massive buildings, hotels, airports, large shopping malls are to be cooling condition completely. In the central air conditioning systems there is a plant room where massive compressor, condenser, quality growth valve and the evaporator are kept in the maximum plant room. They perform all the functions as usual similar to a typical refrigeration system process.

Time For Your Spring Air Conditioner Checkup


It's been a long winter in most of the country, but spring has finally arrived - birds are returning from their winter habitats, the first flowers and plants are beginning to emerge from the thawed earth and you see the branches of the trees in your neighborhood bearing buds which will soon bring forth leaves. It's a great time of year and we all look forward to the warming temperatures and spending more time outdoors. Of course, this means that summer will be here before we know it and with it, the need for air conditioning.

Spring may not be a time when most of us spend too much time thinking about air conditioning, but now is definitely the time to give your air conditioning system's annual spring checkup - put it on to your spring cleaning list and make sure that's your whole home is prepared for the arrival of summer.

There are a number of different things which should be examined as a part of your spring air conditioner checkup; keep reading to learn more about this process - there's more to it than you may have supposed. That's why this is a job best left to the professionals, no matter how handy you may be elsewhere around the home. Central air conditioning units are complex pieces of equipment.

1) The first thing that needs to be checked is your air conditioning unit's coolant levels - you definitely don't want to try cooling your home without having ample coolant in the system. This will be check and if necessary, topped up to the appropriate level. You'll also need to have the disconnect switch looked at to make sure that it is in good working order; this is a vital part of your AC system.

2) Next on the list are your condenser coil and your condensate line. The condenser coil is a key part of your air conditioning unit and if this is not working properly, your AC is not going to work efficiently (or perhaps even at all). The condensate line carries water condensation from the air away from the rest of the unit and if this becomes clogged, your air conditioning unit can become flooded - this should be checked for foreign objects regularly.

3) As part of your spring checkup, the startup capacity will be checked, along with measurements of several other important metrics including testing whether your compressor amperage meets the unit's specifications, the performance of your unit's motor as well as whether your unit's capacitors are performing within the parameters specified by the manufacturer.

4) Testing the safety controls is another important part of spring checkups and maintenance for your central air conditioning unit. Like anything else, safety comes first with your air conditioning unit and your safety controls including various fuses and emergency off switches need to be tested at least once a year to make sure that your air conditioning unit is operating safely.

5) The main switching relay of your air conditioning unit also needs to be evaluated to make sure that it is in good shape. This is the core of the electrical system in the unit and as such needs to be examined as part of your spring checkup. The motors in your unit will also be lubricated if required and your thermostat tested and calibrated to ensure proper functioning for your unit once summer heat sets in.

6) All wiring and connections in your air conditioning unit will need to be checked and tightened to ensure continuing functionality and safety. Air flow including your air filter will also be done during your air conditioning spring check up and if necessary, your air filter will be replaced.

Following all of these internal tests and tune-ups, there will be several tests done within your home as well. Air temperature will be tested during the operation of your air conditioning unit to make sure that your air conditioning is working properly. The connections of the air ducts going into your home from the unit will be checked and reconnected if necessary to prevent cool air from escaping before it even makes its way into your home. Your unit's piping will be inspected to make sure that it is in good shape and free of vibration, the state of your outdoor motor fan checked and your unit's function monitored to make sure that every part of your system is working together properly.

As you can see, there are a lot of different things which need to be looked at as part of your air conditioning unit';s spring checkup; all of them are necessary to make sure that your central air is working efficiently and safely. Now that spring is upon us, it's time to schedule your spring air conditioning checkup so that once the mercury begins to rise; your home will be well prepared.

Finding the Right Air Conditioning Units Prices


The question of finding the right air conditioning units prices for your needs is something that only experts in the area of environmental temperature and how air conditioners affect it can give sound advice on. This is because it is not just the size of your room that you have to take into consideration when selecting the air conditioner that will not be overworked or under worked to provide your place with a comfortable temperature. Things like the climate in your area, the degree to which your place is weather-proofed, the number of people you expect to be occupying the room at a time, the height of the ceiling and similar other conditions have to be considered in air conditioning units prices.

Naturally, the first thing you should do before getting your air conditioning unit is to consult with engineers or people who have done a lot of successful work in air conditioning. If you care to visit websites that deal in air conditioners, they will be only too glad to help you out with air conditioning units prices.

Aside from getting professional help for air conditioning units prices, you need to know something about terms used to describe air conditioners, the better for you to comprehend whatever experts have to say to you.

First you will have to know about SEER or the Seasonal Energy Efficiency Ratio of an air conditioner. The higher the SEER rating of an air conditioner, the more efficient it is in cooling a place. Your consultant will have to relate the cost of energy in your place with the amount of work that will have to be done by an air conditioner as well as the number of estimated hours you need to keep the unit on in a year to be able to pinpoint the best SEER rating for you to go for in your unit. For most purposes, a SEER 10 air conditioner will be suitable for moderate usage while higher SEER ratings (11 or 12) may be needed for more extreme conditions.

Secondly, the noise a unit makes lowers its price. In other terms, silent ones which have a bel rating of 7.6 or less will cost more. You need to research on the different prices of air conditioners with different bel ratings to determine whether the price at which you are getting yours is reasonable enough.

Additionally, the cost of installation will have to be reckoned along with the basic cost of the unit itself as part of air conditioning units prices. If you are buying a wall-type air-conditioner, you will need an aperture in the wall. While it is perfectly possible to have these holes punched out of the wall, it is always better to have them pre-done while the building or house is being constructed, again you will need expert advice to predict where your future air conditioning units should go in the wall. Then you have to have the apertures made and sealed up with a painted metal sheet until it is time to put the air conditioner in.

The Ways An Air Conditioner Compressor Can Fail, and What To Do About It


Air conditioner compressors usually fail due to one of two conditions: time and hours of operation (wear out), or abuse. There are some failures that can occur elsewhere in the system that will cause a compressor failure, but these are less common unless the system has been substantially abused.

Usually abuse is a result of extended running with improper freon charge, or as a consequence of improper service along the way. This improper service can include overcharging, undercharging, installing the wrong starter capacitor as a replacement, removing (rather than repairing/replacing) the thermal limiter, insufficient oil, mixing incompatible oil types, or wrong oil, installing the compressor on a system that had a major burnout without taking proper steps to remove the acid from the system, installing the wrong compressor (too small) for the system, or installing a new compressor on a system that had some other failure that was never diagnosed.

The compressor can fail in only a handful of different ways. It can fail open, fail shorted, experience a bearing failure, or a piston failure (throw a rod), or experience a valve failure. That is pretty much the entire list.

When a compressor fails open, a wire inside the compressor breaks. This is unserviceable and the symptom is that the compressor does not run, though it may hum. If the compressor fails open, and following the steps here does not fix it, then the system may be a good candidate for a new compressor. This failure causes no further failures and won't damage the rest of the system; if the rest of the system is not decrepit then it would be cost effective to just put a new compressor in.

Testing for a failed open compressor is easy. Pop the electrical cover for the compressor off, and remove the wires and the thermal limiter. Using an ohmmeter, measure the impedance from one terminal to another across all three terminals of the compressor. Also measure the impedance to the case of the compressor for all three terminals.

You should read low impedance values for all terminal to terminal connections (a few hundred ohms or less) and you should have a high impedance (several kilo-ohms or greater) for all terminals to the case (which is ground). If any of the terminal to terminal connections is a very high impedance, you have a failed open compressor. In very rare cases, a failed open compressor may show a low impedance to ground from one terminal (which will be one of the terminals associated with the failed open). In this case, the broken wire has moved and is contacting the case. This condition - which is quite rare but not impossible - could cause a breaker to trip and could result in a misdiagnosis of failed short. Be careful here; do an acid test of the contents of the lines before deciding how to proceed with repair.

When a compressor fails short, what happens is that insulation on the wires has worn off or burned off or broken inside the compressor. This allows a wire on a motor winding to touch something it should not touch - most commonly itself a turn or two further along on the motor winding. This results in a "shorted winding" which will stop the compressor immediately and cause it to heat up and burn internally.

Bad bearings can cause a failed short. Either the rotor wobbles enough to contact the stator, resulting in insulation damage that shorts the rotor either to ground or to the stator, or end bearing wear can allow the stator to shift down over time until it begins to rub against the stator ends or the housing.

Usually when one of these shorts occur, it is not immediately a hard short - meaning that initially the contact is intermittent and comes and goes. Every time the short occurs, the compressor torque drops sharply, the compressor may shudder a bit visibly as a result, and this shudder shakes the winding enough to separate the short. While the short is in place, the current through the shorted winding shoots up and a lot of heat is produced. Also, usually the short will blow some sparks - which produces acid inside the air conditioner system by decomposing the freon into a mixture of hydrochloric and hydrofluoric acid.

Over time (possibly a couple of weeks, usually less) the shuddering and the sparking and the heat and the acid cause insulation to fail rapidly on the winding. Ultimately, the winding loses enough insulation that the inside of the compressor is literally burning. This will only go on for a few minutes but in that time the compressor destroys itself and fills the system with acid. Then the compressor stops. It may at that time melt a wire loose and short to the housing (which can trip your house main breaker) or it may not. If the initial cause of the failure was bad bearings causing the rotor to rub, then usually when the thing finally dies it will be shorted to the housing.

If it shorts to the housing, it will blow fuses and/or breakers and your ohmmeter will show a very low impedance from one or more windings to ground. If it does not short to the housing, then it will just stop. You still establish the type of failure using an ohmmeter.

You cannot directly diagnose a failed short with an ohmmeter unless it shorts to the housing - a shorted winding won't show up with an ohmmeter though it would with an inductance meter (but who has one of those?) Instead, you have to infer the failed short. You do this by establishing the the ohmmeter gives normal readings, the starter capacitor is good, power is arriving at the compressor, AND an acid test of the freon shows acid present.

With a failed short, just give up. Change everything, including the lines if possible. It is not worth fixing; it is full of acid and therefore is all junk. Further, a failed short could have been initially induced by some other failure in the system that caused a compressor overload; by replacing the whole system you also will get rid of that potential other problem.

Less commonly, a compressor will have a bearing failure, piston failure or a valve failure. These mechanical failures usually just signal wear out but could signal abuse (low lubricant levels, thermal limiter removed so compressor overheats, chronic low freon condition due to un-repaired leaks). More rarely, they can signal another failure in the system such as a reversing valve problem or an expansion valve problem that winds up letting liquid freon get into the suction side of the compressor.

If a bearing fails, usually you will know because the compressor will sound like a motor with a bad bearing, or it will lock up and refuse to run. In the worst case, the rotor will wobble, the windings will rub on the stator, and you will wind up with a failed short.

If the compressor locks up mechanically and fails to run, you will know because it will buzz very loudly for a few seconds and may shudder (just like any stalled motor) until the thermal limiter cuts it off. When you do your electrical checks, you will find no evidence of failed open or failed short. The acid test will show no acid. In this case, you might try a hard-start kit but if the compressor has failed mechanically the hard-start kit won't get the compressor to start. In this case, replacing the compressor is a good plan so long as the rest of the system is not decrepit. After replacing the compressor, you must carefully analyze the performance of the entire system to determine whether the compressor problem was induced by something else.

Rarely, the compressor will experience a valve failure. In this case, it will either sit there and appear to run happily but will pump no fluid (valve won't close), or it will lock up due to an inability to move the fluid out of the compression chamber (valve won't open). If it is running happily, then once you have established that there is indeed plenty of freon in the system, but nothing is moving, then you have no choice but to change the compressor. Again, a system with a compressor that has had a valve failure is a good candidate for a new compressor.

Now, if the compressor is mechanically locked up it could be because of a couple of things. If the compressor is on a heat pump, make sure the reversing valve is not stuck half way. Also make sure the expansion valve is working; if it is blocked it can lock the compressor. Also make sure the filter is not clogged. I once saw a system that had a locked compressor due to liquid lock. Some idiot had "serviced" the system by adding freon, and adding freon, and adding freon until the thing was completely full of liquid. Trust me; that does not work.

Should diagnosis show a clogged filter, then this should be taken as positive evidence of some failure in the system OTHER than a compressor failure. Typically, it will be metal fragments out of the compressor that clogs the filter. This can only happen if something is causing the compressor to wear very rapidly, particularly in the pistons, the rings, the bores, and the bearings. Either the compressor has vastly insufficient lubrication OR (and more commonly) liquid freon is getting into the compressor on the suction line. This behavior must be stopped. Look at the expansion valve and at the reversing valve (for a heat pump).

Often an old system experiences enough mechanical wear internally that it is "worn in" and needs more torque to start against the system load than can be delivered. This system will sound just like one with a locked bearing; the compressor will buzz loudly for a few seconds then the thermal limiter will kill it. Occasionally, this system will start right up if you whack the compressor with a rubber mallet while it is buzzing. Such a system is a good candidate for a hard-start kit. This kit stores energy and, when the compressor is told to start, dumps extra current into the compressor for a second or so. This overloads the compressor, but gives some extra torque for a short time and is often enough to make that compressor run again. I have had hard-start kits give me an extra 8 or 9 years in some old units that otherwise I would have been replacing. Conversely, I have had them give only a few months. It is your call, but considering how cheap a hard-start kit is, it is worth trying when the symptoms are as described.

And this, in a nutshell, is what can happen to an air conditioner compressor and what you can do about it.

How Do Central Air Conditioners Work?


Want to relax in the serene and cool indoors of your home during the hot summer? What could be a better way than to install central air conditioning systems in your home to maximize the cooling effect.

Central air conditioners are perfect for cooling the entire house rather than a single room.

These are preferred by most people who can afford it for cooling their residential spaces. The basic way central air conditioners work is through throwing hot air out of the house and circulating the cool air through the rooms.

Most people find central air conditioning systems more convenient and comfortable compared to portable or window ACs as they keep the temperature throughout the house the same. Central air conditioning is automatic as it turns ON and OFF when required keeping electricity bills under control.

Besides the regular functions that most central ACs perform, adding accessories like thermostats and electronic air cleaners can greatly facilitate the way these units perform.
Central AC systems are comprised of two basic parts, the hot and the cold side.

The hot side is the part that is out of the home while the cold side is one that is inside. The outside/condensing coil mainly absorbs hot air from inside the house and throws it out. This coil comprises of an electrical disconnect switch, a compressor fan, motor and a condenser coil.

To support the function of the condensing coil, the indoor section and gas handler works to circulate the cool air within the home. This system is comprised of a blower, a condensate tray/drain and pump and an evaporation coil. The indoor as well as outdoor units, work together using Freon as a cooling agent for keeping your house cool on hot summer days.

A detail duct work accompanies split units for better performance. However it is important to take special care for maintaining the central air conditioning systems to keep them working perfectly. Their up keep is not very difficult and simply requires keeping all parts dirt free, oiling the motor and replacing the filter.
In short central air conditioning systems can prove to be a highly affordable way of making your home a haven after a long and hot day of work.

Top 3 Reasons For Getting Air Conditioning Ducts Cleaned At Regular Intervals


Have you not gotten the air conditioning ducts in your home cleaned anytime soon? Then it might be high time to consider getting that done. HVAC system controls the quality of air in your entire household, and any lack of care may severely affect the health of people living in your home. The problems are even worse during the colder months, when opening the doors and windows is not exactly an option. Here are the top three reasons why you should contact air duct cleaning services at regular intervals:

1. Mold deposits visible inside the ducts: A lot of moisture is collected inside the air conditioning ducts on a regular basis. This can easily lead to mold deposits forming inside the ducts in the long run. The spores from the molds contaminate the air in your home, and lead to allergic reactions in your family members and pets alike. The most common symptoms of mold allergies include shortness of breath, wheezing sound while breathing and noses clogged up with mucus.

2. Rodents and insects making the ducts their home: If the network of air conditioning ducts in your home is particularly large, then rodents and insects can actually start living in it. That would not be a problem per se, if particles from their fecal matters did not get introduced in the air in your home. Keep these uninvited guests away from your AC ducts at all costs.

3. Dust cakes forming inside the ducts: Have you noticed snow like deposits inside the ducts of the HVAC system in your home? Be wary - these deposits can do a lot worse than simply clogging up the air conditioner and heater outlets. These dust cakes may contain as many as 250 different allergens, or even more if you are really unlucky. Get that icky stuff cleaned from inside the ducts as soon as possible.

Always get air conditioning ducts cleaned up by experienced professionals. The health of you and your family depends on it. There are several reputable organizations out there that provide air conditioning services (including installation and repair), so finding an organization for your requirements might not be that tough. For starters, you can check out airconditioning-filter.com, which is known to provide both these services and also for having a group of highly experienced technicians on board. They should be able to take care of the HVAC system in your home, without forcing you to stretch your budget beyond the comfort zone.

Tips for Buying the Right Air Conditioning Parts


According to recent news, there is a rise in the sale of air conditioners and air conditioning spare parts after the revival of the real estate sector. An air conditioner consists of an evaporator, a condenser and a compressor. The evaporator is fixed on the inside of an air conditioner, while the condenser and compressor are located on the exterior.

The number of dealers offering air conditioners and air conditioning parts are also increasing, parallel to the growing demands. This has given birth to endless avenues and options opening up for customers, which has made the choice very vast for potential customers. Keeping your requirements and budget in mind, the following are some tips designed to help you make a worthwhile investment in air conditioning parts.

Get Parts That You Actually Require - People usually end up buying wrong air conditioning spare parts because they are not sure about the actual requirement. It is obviously a waste of money to buy parts that are either outdated or do not fully support the air conditioner installed. While some of the parts may still be used, the longevity and service quality of the air conditioner will be compromised greatly.

Check Efficiency Ratings - Just like it is very important to check the efficiency ratings before buying the main machine, it is also compulsory to check the ratings before buying air conditioning parts if you want to make a worthwhile investment. Checking efficiency ratings is important because it is considered a useful indicator of the quality and superiority of the products over others.

Professional Assistance - In order to buy just-the-right air conditioning spare parts, you should seek professional assistance. Soliciting assistance from an expert will ensure that you are buying the right parts, from the right dealer, and at the right price. This phase is important since the installation of certain parts may cause damage to the air conditioning unit instead of doing any good.

Dealer Authenticity - It is very important to check the dealer's authenticity, regardless of his availability status. Therefore, this check is not only applicable on online dealers, but should also be conducted for offline dealers in the same way. Check for reviews from referrals, efficiency ratings, authoritarian stamps and consult previous clients of the dealers to witness authenticity before purchasing.

You may also like to pay attention of the technical details to make sure you have the right air conditioning spare parts in hand. The noise level of different parts, durability of the compressor coil and longevity of the product itself should be checked thoroughly before you make your final investment decision.

A Look At The Evolution Of The Air Conditioner


Today, we take it for granted that by flipping a switch; we can turn on our air conditioner and enjoy its cooling effects. In fact, there are even portable models available that have made it possible to take the AC from one room to another. What is more, these appliances are commonly used in buildings throughout our country and in the rest of the world as well. However, it does pay to understand a little bit more about the history of the air conditioner as then you will realize where it all began and where we are today. In the beginning, the rich and affluent people of Egypt were the first to enjoy the wonderful cooling of aqueduct water that was made to traverse the inside of a buildings walls. However, Egyptians had to pay a high cost for this water which was an expensive commodity in that country and in those days.

Persians also knew how to cool things down and in medieval Persia there were rich Persians that enjoyed the luxury of home air conditioning. However, they made use of wind rather that water.

Soon, their ideas were modified and use of liquefied ammonia which was made to evaporate was used to help to cool the air down. The person credited with this discovery was the British scientist Michael Faraday who made his discovery in 1820. About two decades later, an American called Dr. John Gorrie managed to make an ice maker which could be used to cool down the air and this he demonstrated in a Floridian hospital.

Industrial needs led to the invention of the first air conditioner and this was done by Willis Havilland Carrier whose invention in the year 1902 helped in cooling as well as humidifying the air inside a printers plants. It was a person called Stuart W. Cramer who actually first coined the term air conditioning and it referred to a method of adding moisture to the air in order to cool the atmosphere.

In the earliest air conditioners, toxic gases would be used but it was a person called Thomas Midgley Jr. Who created, in the year 1928 the first Freon refrigerant. Though this was a major discovery at the time, now we realize that Freon is bad for the Ozone layer.

An air conditioner is course used to cool our homes as well as offices. There are however other uses as well including being used to filter out harmful particles from the air and this kind of usage are is widely applied in operation theaters in hospitals.

Air conditioning can also be used to help people overcome allergies. This is because an air conditioner can also help in the removal of pollen and dander as well as dust which are the reasons why people suffer from allergies of different kinds.

There are a few air conditioner models that can also act as dehumidifiers and such models are able to remove the unwanted excessive moisture out of the air and this will make the room much more comfortable. We can certainly thank our lucky stars that some inventive geniuses found out how to air condition our homes and offices!

Using Split System Air Conditioner


Due to the inconvenience from tubing and duct work related to installing traditional air conditioners, the split system air conditioner has become popular among consumers today. A split system air conditioner does not need any duct work or holes in your walls just to provide cooler air.

Many individuals and even companies prefer the use of split type air conditioning systems because they are able to save space in terms of installation. A split type unit includes a compressor that is positioned outside the room or establishment while its condenser is installed or mounted inside the room. You do not need to put a hole in the walls for installing split types. You only have to determine the right place or spot in which you prefer to position the condenser. Since most models or designs of split system air conditioners are free standing or upright, you can choose the colors that suit the interior of your workplace, room, or home.

Apart from providing cooler air to any area you want it stationed, a split system air conditioner saves so much space. In fact, it can also serve as part of your interior specifically in empty spaces. A split type air conditioning unit can provide you safety and privacy as it can serve as cover against any intruder in your area.

In addition, split type air conditioning systems produce much lesser noise as compared to regular window type or central air conditioning systems. This is because the noise coming from the compressor is outside the area that needs cooling. You would not be able to hear the noise that most compressors from window type air conditioners produce because the compressor of split types is positioned outside.

When choosing an air conditioning unit, it is best to determine where you want them positioned as well as the size of the area you want it stationed to obtain best results in terms of cooling.

The Vital Role Hired Air Conditioning Plays on Film Sets


According to numerous celebrity gossip websites, in 2006 American actress Lindsay Lohan collapsed on the set of her movie Georgia Rule, after a grueling 12-hour shoot in 105 degree temperatures and was hospitalised. She is not the first actor to suffer such a fate through simply being too hot at work. There have been countless similar instances over the years: on film sets, in TV studios, on music video production sets and sound stages, during the indoor and outdoor shooting of adverts, and even in the creation of animated sequences and feature-length animated films.

Each of these different businesses are worth billions of pounds, and producers are always keen to keep expenses down. That is why filming often takes place around the clock - to minimise costs and maximise profit.

The downside of all this is that essential equipment such as heat-producing lighting, cameras and sound gear will be almost constantly operational on set. Sometimes lighting is used not to light a specific scene, but for Health & Safety reasons; to ensure actors do not trip, fall and injure themselves on set when filming or waiting to be "called" to scene." These extra lights add to the overall heat created.

Also, depending on the period or style of the production being made, actors may be wearing a variety of costumes (some classical dramas can involve cast members having to wear several layers of clothing, beneath blisteringly hot lighting). Production support staff working in remote and hot locations (usually in tents) can also 'feel the heat', so their well-being also needs to be considered.

The good news is that suitable air conditioners can be hired from an air con hire specialist to help combat the sometimes sweltering heat on film sets.

Hiring Air Con Makes Perfect Sense

To ensure that filming can continue in the best possible conditions, it makes sense for producers to rent portable air conditioning units, to maintain comfortable surroundings for all (and also to help keep equipment cool as far as possible).

A key advantage of leasing air con units for film sets from an expert, rather than buying, is that the most appropriate units can be supplied to best suit each individual film location. An established air conditioning rental specialist with experience in providing solutions to the film industry will have the equipment, personnel and expertise to ensure the most appropriate air con units are made available each time (even for the most unusual of locations).

When air conditioning in hot weather is a must on set, but the production team just want it to arrive and be installed with minimum disruption, it is vital that the rental specialist is experienced in working in this particular field. Every film set will be different and have differing air con requirements. This is something a good hire team will see as a great challenge. They will pull out all the stops to ensure that the right solution is provided, in an affordable and hassle-free way.

About Producers' On-Set Responsibilities

Although there are no specific rules and regulations in place to ensure actors work in a comfortable temperature on a film set (or other) - as these would be impossible to devise and enforce. By law, producers do have a responsibility to ensure, as far as is reasonably practicable, that persons (and animals) working on set are not exposed to risks to their health and safety.

As part of their production team, a producer should have at least one experienced crew member who is aware of possible Health & Safety issues.

Time Is Money

If film production ceases due to excessive conditions, tens if not hundreds of people will all be wasting time on set waiting for production to restart. This can have huge budgetary implications. To a producer, a good air conditioning rental specialist can, therefore, be worth their weight in gold.

Throughout the filming process, in fact, any area where financial savings can be made is seen by a producer as a godsend. Hiring (rather than buying) air con is a perfect example of this. Even on sets and in locations where space is at a premium (and/or where noise needs to be kept to a minimum), an experienced specialist will be able to advise on the best portable air conditioning solution - the most suitable units can be quickly delivered, positioned and made operational, often without a single minute's filming being lost.

Choosing The Right Central Air Conditioning Unit For Your Home


As the hot days of summer start to appear, it can quickly become apparent that room fans blowing hot air around simply don't cut the heat. If you're considering upgrading to a central air conditioning system there are two different kinds of systems to pick from. A package system is rare and probably not the one most home owners will be using. The more common type is the split system that places components of the air conditioning system in the home while other parts are placed outside of the home.

Before you can select the actual unit you will purchase you will need to know what size of unit will fit your home needs. If the unit is too large it will leave the air feeling clammy and wet- not cold and if the unit is too small it won't make much of a dent in the hot air at all. In order to calculate the size of unit needed a contractor can do a heat gain calculation and recommend the size you will need.

Many factors come into play that will ultimately affect what size of air conditioning installation unit your home will require including the size of your home, how old the home is, how insulated the attic and walls are and the type and placement of windows and doors. To get the most efficient use of central air it is important that your home be well insulated. Older homes or homes that are poorly insulated should be insulated better to help the ac work well and be more energy efficient.

But it's not just a matter of putting more insulation layers in the attic or walls. There are other ways energy is lost through the home that many home owners don't consider such as leaky seals around windows and doors, and windows that are not energy efficient and allow hot air in and cold air out. It is well worth the upgrade to ensure the whole home is properly insulated to make your energy bill lower and enjoy all of the benefits a central air system can offer.

And since most systems in the United States require a duct system to deliver the cool air throughout the house this is another source of potential energy loss. If the ducts for the cooling system aren't sufficiently sealed and working properly the air conditioning unit will be working over-time to get the cold air through the system effectively.

Even conditions outside of the home can affect how well your air conditioning installation works. Having a home protected from the suns direct rays with landscaping and overhanging trees can make the job of your central air unit easier.

Since there are so many factors that can influence how well your system works make sure to have a contractor who specializes in central air conditioning installation units advise you of what size will work best for your home and check your home's insulation needs before you go any further in the process to select a unit that is right for you.
