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.

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.

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.

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.

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.

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.

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.

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.

Air Conditioning Systems V Central Heating Systems

I'm always amazed at the reluctance of the British to part company with old ideas in favor of new products and lifestyles. Air conditioning is a great example of a really great product but homeowners are still reluctant to install. So the question is, why?

Air Conditioning Systems In UK Offices

It's a little bit crazy but I would imagine 80% of UK offices and commercial premises are heated and cooled by air conditioning systems but yet it would never occur to the workers within these premises to install air conditioning systems in their homes. It's not like people don't know what it is it just that they associate air conditioning with offices and central heating with homes.

Central Heating Is The Most Popular in UK Homes

There is no argument that central heating is currently heating about 80% of UK homes but if it was really efficient then why is it not more widely used in offices and commercial buildings?

What About The British Climate - Maybe That's The Answer

Sure enough if you go into mainland Europe and visit France or Italy you will see a remarkable difference in the use of heating systems. Anybody driving around Paris or Rome would most certainly believe that almost every apartment has air conditioning especially when you see the thousands of aircon boxes perched on window sills. But yet both Paris and Rome get cold winters and snow just like here in the UK so that can't be the reason whey we use central heating and they use aircon. It could be that the Europeans get better warmer weather in the summer and they need the aircon in the summer where we can struggle by as we have done in the past.

The British Don't Like Change

Personally, I think that no matter what research you do as to why the Europeans favor aircon you will eventually come to the conclusion that what it really comes down to is that the British are reluctant to change. They are a nation of putter-uppers who love to suffer and whine afterwards. Take it from me, I've been here for 35 years and I know. To further my argument I can tell you that the British still use copper pipe to install central heating and plumbing in their homes when plastic pipes and fitting have been available for 20 years or so. Plastic pipes are now used by all the UK utility companies to serve 30million homes their gas and water but yet the British homeowner wants to stay with copper because that what they had in the past. They simply hate changing things even though it is in their own interest and that they will be better off because of it.

Conclusion

Get some quotes for air conditioning the next time your central heating goes on the blink. You can get quotes and compare costs for air conditioning systems at Air Conditioning Supermarket, the UK's fastest growing Price Comparison site for Aircon services.

Opting For a Split System Air Conditioner

Many people have the common notion that a split system air conditioner can only be used for homes or residential areas. However, it can also be used in commercial establishments such as offices, hospitals, classrooms, and other areas. This is because a split system air conditioner does not require duct work and is able to meet specific cooling requirements through setting it to different temperatures.

A split system air conditioner is great for residential areas or homes because they are able to provide home-owners the choice in terms of efficiency as compared to other central air conditioning units. Some homes can obtain benefits from a split system because they can be added for cooling a room without the need for duct work.

Multi Splits can be combined with window type air conditioning systems so that you have alternatives for saving energy as well as money. When multi splits are combined with central air systems, you can obtain better cooling capacity. More so, you have the option of turning off your larger unit to save money and power consumption.

If you are not sure about the installation for split type air conditioning systems, many manufacturers and companies offer installation services. They help customers with proper installation. More so, if you are in multiple family homes, they can help you install the multi split air conditioning unit in the most workable area for better cooling and zoning.

Nevertheless, splits are the air conditioner perfect for any area. They are more energy efficient and provide cleaner and safer air. They are able to discard odours such as cooking odours, pet smells, or cigarette smoke. Thus, they can also provide health benefits especially for individuals with respiratory problems such as asthma. They can minimize dust, pollen, and other pollutants that can affect the respiratory system.

Air Con - Various Types of Air Conditioning Units

It has become a must to have air conditioning in today's homes and offices. This need helps with comfort levels during the hot summer months, but also provides an optimal environment for electronics, appliances and computers. These items, commonly found in modern homes and offices, contain components that should not get too hot. Heat can make the components fail or at very least lose their efficiency. In order to maintain the efficiency of your air conditioner(s) you need to make sure to get them serviced regularly.

One of the industry leaders in air conditioning is air con. They carry a wide variety of units from portable to stationery that are energy efficient, functional and most units are programmable. The various types of air con units include:

Portable - Portable units are just what the name implies. These can be moved from room to room easily. Most of these air conditioners are used to keep a specific room or area cool, much like a window unit. For instance, if you have a home office with a server or PC, this will keep that room cooler than the rest of the house and keep your equipment running at top performance. These units are energy efficient and can be programmed to shut on or off as needed.

Window - Window units are those air conditioners that fit into a window. They are installed easily (more so today than in past years) and have options for window fitting so you do not let in hot air from outside due to cracks and crevices like older models. These can also be programmed so you can have complete control over the temperature in your home or office.

Built-in Stationery - This can include ceiling cassette, ceiling ducted, ceiling suspended and wall mounted units. All air con stationery units are energy efficient and can keep you comfortable while protecting your valuable computer appliances and electronics from the heat.

One of the best things about these air conditioning units is that they are compact. They are also energy efficient, programmable and offer quiet operation which is important to today's consumer. You may also find some of these units come with remote control operation so you can control your home or office environment simply with the touch of a button.

With so many choices in air con units, there is no reason you should have to survive the hot months without air. It is also very important to have the ability to protect your expensive equipment throughout your home. Remember, regular maintenance and service on your air conditioning is an important part of keeping your unit running at peak performance. Regularly scheduled servicing can also save you money over buying new units.

Why Portable Air Conditioning Units Are Such a Cool Concept

Portable air conditioning units have been specially designed to meet the cooling needs of someone who wants to cool a very small area such as an apartment, or an office or a single room. The goal is that they use this smaller and very portable unit to cool off a little area rather than running central air that can cost a lot of money to run.

Save Money

Before the introduction of these very handy portable air conditioning units, there was no way for people to save money if they had a central air conditioning system. When a room got to warm and needed cool air, either you had to open a window or use a fan or run the entire system which might cool every room, even the ones who didn't need it.

That meant people were spending a huge amount on their electricity bills and wasting electricity on rooms that were not even hot. Plus if you choose to use this machine you will discover that they are very energy efficient and therefore can lower your electricity bills even more.

Easy to Install

One of the reasons these small air conditioners are so popular is that they are extremely easy to set up. They don't need an elaborate setup, you just need a window for the vent to go out and then you are ready to go. Plug it in and turn it on and any room, no matter how small or big can be cooled very efficiently.

How They Work

All of the portable systems are built with wheels, are extremely small in size and can very easily be store away when not in use. Usually you will find these machines come in capacities of 6,000 BTU to 60,000 BTU. You can find any size you need for any size room.

Air Conditioning Units

Air conditioners are almost a basic necessity of life and there are only a few people left that do not have these revolutionary machines. Most people have air conditioning units in their homes to keep their selves comfortable and away from the heat and humidity. Almost all offices, factories and plants have air conditioning units as well.

There are several air conditioning units for different kinds of interiors. There are small units used mostly for houses or apartments and there are large units used for shopping malls or offices.

There are different kinds of air conditioning units and among the most common units are the window and through-wall types. These types of air conditioners can be categorized as unitary or packaged terminal units. The unitary systems are designed to be used in small rooms and they are fitted in a wall or window with an exhaust sticking outside the wall. This machine works by sending air from the room over an evaporator thus cooling it. At the same time this machine takes the heat from the room and brings it out to the environment. The packaged terminal units or PTAC systems are more commonly used in large rooms such as hotel lobbies and ballrooms. The PTAC systems are designed with two units called terminal packages. The first unit which is the evaporative unit can be found in the interior of a large building or room, while the condensing unit can be found in the exterior. Both units are connected to each other by a tube wherein the air outside passes through it to be cooled and sent to the interior while hot air from the room is sent out to the environment.

Another unit is the evaporative cooler. This machine is commonly used in the Middle East and it is so common in Iran that some people refer to it as "Persian coolers". These air conditioners work by taking in air from outside and sending through a wet sponge which decreases the sensible heat (energy exchange during a change in temperature).

Portable air conditioners are air conditioning units that can be carried around to different locations in a building or room to cool a specific location. Most of these air conditioners are designed to be refrigeration-based machines and not evaporative. Refrigeration-type air conditioners cool air by continually sending air through the machine and out until the temperature of the room adjusts to the desired setting.

Is Your AC Making You Sick?

No matter how clean your home or office environment is, there are countless unseen pollutants assaulting your senses. These toxic elements often go under the radar since they're not seen and their effects are usually associated with other causes or conditions. But if you have two or more of the symptoms listed below, chances are these toxic pollutants are running rampant in your home.

* frequent colds
* stomach pains
* ear infections
* frequent headaches
* allergic reactions
* asthma
* coughing
* sneezing
* wheezing
* itchy skin
* sore nasal passages
* irritated throat
* watery eyes/dry eyes
* hypersensitivity
* skin care problems

If you have any multiple combination of these symptoms, it's very likely directly linked to your central AC unit.

So what's making you sick?

There are two main causes for sickness associated with air conditioners: unnatural coldness and mold. Unnatural coldness, low cooling temperatures, often lead to illness and are relatively easy to control. The other cause, mold, is a notorious infiltrator that is nearly impossible to get rid of once its settled in your home.

Unnatural Coldness: A runny nose, watery eyes, and other basic flu-like symptoms, are our body's own natural response to unnatural coldness - but it isn't just a matter of temperature. Centrally air conditioned air is usually very dry since the units do not come with a humidifier function. This causes the delicate lining of the nose and mouth to become cracked and dry, leading to nose bleeds and causing the body to overcompensate with excess fluid production.

Mold: Molds are microscopic fungi in the same fungal family as mushrooms and yeasts. Highly adaptive, fungi grow and reproduce rapidly, breaking out in trail of expanding circular patches known as mold spores. Mold occurs in any damp organic environment. You've probably seen mold on spoiled food, on pieces of decayed wood, wet windowsills, or on papers and fabrics stored in a damp musty place.

With discovering over 270 species of mold, and with a difference between indoor and outdoor mold, there are a number of health risks associated with this contaminant. Several factors have to be evaluated in order to weigh the magnitude of health hazards associated with this toxic invader. These include:

* Type of mold
* Amount and degree of exposure
* Health conditions of the person inhabiting the home

Based on these factors, a person living in a moldy environment can have health problems ranging from allergies to serious illness. And as with any disease or compromised environment, pregnant women, infants, young children, the elderly, and those with significant health problems (especially respiratory diseases and/or weakened immune systems), are far more at risk if exposed to mold.

Mold inside your air conditioner

The most dangerous type of mold is the kind that's hidden. Going unseen and undetected, it spreads rapidly throughout your room, exposing you and your family to countless health problems. If you do detect slight mold, at either mild to low moderate levels, you can remove it through thorough cleaning, exposure to sunlight, and through proper ventilation.

However, detecting and removing mold is far trickier with central air conditioning systems. Most people aren't even aware that mold can and probably is inside your air ducts and vents. If you have several of the symptoms listed above, but are confident that your home doesn't have mold, chances are it's hidden in your central AC system. Aircon systems are one of the main mold producing appliances because they are a highly suitable environment for fungus. The high density of moisture and dust makes this a perfect breeding ground.

If you've ever cleaned your filter, you were probably surprised by how dirty it was. Now imagine air conditioner ducts and vents that you aren't able to look into. You'd be surprised by how dirty the return duct is - dirt, pet hair, drywall dust, all clumped together and funneled through air ducts, vents, and straight to your lungs. If you take into consideration that the vents in each room may not be sealed well, it is very likely that what's in your ducts is getting blown out into your living space, all over your hair and skin, your food, your bed sheets, your makeup and hygiene products. With such scary stats, it's no surprise that the number of people with Legionnaires Disease has gone up - a nasty flu-like bacteria that thrives in AC systems.

This unseen assault on your health takes an additional toll if you take account the time you spend listless from being ill, including missed days of work, money lost - all of which could be prevented.
What you can do

Ventilate your space: Crack open a window and let some fresh air come through. Keep in mind that opening a couple window for cross-ventilation is very different from switching on a fan. While using a fan is a great idea for helping prevent mold, it's not ideal for getting rid of mold. Once mold has set in, fans only ensure that the mold problem gets circulated faster and into more crevasses and cracks - making the problem impossible to spot till it's too late.

Clean your filter: Air conditioner filters were designed and installed to prevent the spread of bacteria and viruses. However, as they collect these specimen, filters themselves can inadvertently become hosts to bacteria. Pollutants build up and get caught in the filter so that as air blows on it, they disperse from the filter and into the air you breathe.

The best thing to do if you've been using your central AC unit, is to get a professional to come in and check for mold spores - which can linger in the hoses/ducts. If mold spores are found, then you need to contract a professional to clean the area ASAP. Make sure whoever you contract does not use just a brush or vacuum. Using just a brush or vacuum, without any chemical cleaning solutions, will only loosen mold and bacteria and make you more susceptible to breathing it in. Here are some key things to keep in mind if hiring a serviceman:

1. Did they clean the blower unit?
2. Is the chemical cleaner they use certified and non toxic?
3. Does the chemical have anti-fungi and anti-bacterial properties
4. Make sure the serviceman doesn't just clean the unit with a vacuum and brush. This will only agitate the bacteria and viruses breeding there, ensuring you and your family get sick.

It's ideal to have your filter cleaned or replaced once a month. If this sounds like too much of a hassle, or you don't want to bear the burden of hiring costly professionals, then you may want to consider purchasing a portable AC.

Get a portable AC: Not only will you not have the mold problems as described above, portable air conditioners also save you the burden of hiring professional cleaners to clean your ducts and vents. Portable room air conditioners run for 1/4 the cost as central AC units.

In addition to being able to find AC units with multiple filters, many now also pair as humidifiers - which will prevent the dryness problems associated with common central AC units.

To live healthily, the air you breathe into your body must be clean, especially for your bedroom where you spend a considerable portion of your time completely defenseless - while you sleep! We live in a world where we have more pollution in our air than any time before. You want your home and your sanctuary to also be a fortress against foreign pollutants.

7 Tips to Increase the Longevity of Your Split Air Conditioner

The global warming has wrecked havoc on the earth as the temperature is rising and touching a new high every year. The people across the globe are suffering from the ill effects of global warming. Coupled with the scorching heat, the humidity has made life tougher than ever before. To save themselves from this unusual climatic condition, many people have fallen back on air conditioners a lot.

Whether you buy a split AC (air conditioner) or a window AC, the most important thing is to know whether they will perform smartly under tough circumstances. Since, we tend to overuse the air conditioners during the summer, we need to be prepared for their maintenance just incase they fail to perform up to the desired level. Take a look at some of the maintenance tips for split ACs that should be applied to boost the efficiency of your split air conditioner.

The smooth functioning of a product depends on its proper maintenance. So, if you have a product, then you need to take god care of it. In case of an AC whether domestic or commercial, the following points should be noted for better performance and durability of the product. The various components of it include:

1. Air conditioning filter is an important part of an AC. It should be changed every month or every two months regularly depending on its use. If not the air would be dirty and filled with pollutants. The dirty air conditioning filters also increases the air conditioning repair and maintenance cost.

2. Another important part is the compressor. It compresses low pressure, low volume gas making them the high pressure, high temperature and the gas needed for the AC. It also removes vapor from the evaporator to maintain a low boiling point. Make sure to clean the compressor regularly to get cool and refreshing air. Oil specially designed for the ACs can be used for its longevity.

3. When air passes through the system, the evaporator coil absorbs the heat to provide cold air through out the space. Replacing the old evaporator coil improves the air flow and air circulation inside the home.

4. Air conditioning maintenance also includes cleaning of air ducts or ducts. In the air conditioning system, air ducts are spread through out the entire house keeping the area cool and pleasant. Hence, the ductwork ought to be cleaned regularly to remove the dust collected on air ducts.

5. All air conditioning system use refrigerant to absorb the excess heat and supply cool air inside the house. Sometimes there might be a refrigerant leak. So, a reliable air conditioning company or contractor should be called to check and repair that part.

6. Sometimes there might be problem with the heating and split air conditioning of your air conditioner. You need to clean your air filters. If, still the problem continues, then it`s time to call an expert.

7. In some of the cases ice blocks the tube and no cold air comes from the air conditioning filter instead of the filters recently cleaned. It indicates that the air conditioning refrigerant is low and needs to be adjusted or replaced.

Although the running cost of both window and split AC is almost the same, the power consumption of a split AC could be little higher because of the additional motor it requires. Moreover, the capital expenditure of it is a bit higher than the window AC as well. A split air conditioner scores higher than a window air conditioner because of its `silence` feature. The compressor of a split air conditioner is kept away from the indoor unit and thus, ensures complete silence inside your room.

A Few Words About Chillers and Central Air Conditioning Systems

Of course you can always rely on it the fact that any specialist in refrigeration devices can render assistance to you when it`s time and you need to choose a small chiller but a large commercial one that will sort your needs. However, it is always better to know a little more than what chillers are designed to chill. Being well informed about these units, their structure and operation will help you and the consulting shop assistant focus on your needs. Or if you already own one this knowledge is important to you to comprehend what type of chillers you have and how to maintain it.

A chiller is a refrigeration device that is designed to cool water. This is the main way of cooling in a complex climate system. There are units that operate only for cooling as well those that can also work as thermal pumps (bidirectional, double-acting chillers).

The core cold generators are usually fan coil units (simple devices consisting of a heating or a cooling coil and a fan) and central air-conditioners. The chiller is connected to them by means of tubing and a pumping station.

Types of chillers

The basic categories that classify these refrigeration devices are established according to their cooling and connection characteristics.

• outdoor air-cooled chillers


• indoor air-cooled chillers


• air-cooled chillers with detachable condenser


• water-cooled chillers (connected to water-cooling tower or natural running water reservoir)

Each of the basic types mentioned above can vary due to the type of compressor they have and other various configurations used.

Central air conditioning system

Chillers are used almost in every sphere of life nowadays, but they are extremely popular with central air conditioning systems for larger buildings. The chiller unit with fan coil system allows independent and free temperature regulation in a great number of premises at the over the same period of time. In this case the chiller is a source of the cold in the system; it cools the water flowing through the tubing. The latter is used to control the temperature in the space where they are installed in, they can change their performance very quickly so are very flexibly in operation.

This kind of central air conditioning system is used in large buildings such as office centres, hotels, hospitals, shopping malls, hypermarkets and large residential buildings, where there is need to regulate temperature in various separate premises.

Such air conditioning system offers a nice flexibility in air-conditioning of a great number of separate premises. One chiller can be connected to a bulk of fan coil units and heat exchangers offering central air-conditioning or air- supply ventilation across the complete platform. Each consumer can virtually act separately from each other and change the mode of operation to on or off as required. The chiller and fan coil units are not limited by distance and their performance is determined by pumping station and tubing heat insulation capacity. If properly maintained according to the given instructions all types of quality chillers will serve well and last for a good number of years before needing replacement.

Compact, Convenient and Cost Effective Portable Air Conditioning Units
