Why Window Air Conditioners Ice Up


One of the most frustrating problems with a window air conditioner is if it starts to ice up. For the owner of the air conditioner is can be perplexing.

When this problem occurs most people immediately think it is the fault of the refrigerant gas. More often the cause is the result of other difficulties.

It is most often the result of poor airflow.

Any time the airflow through an air conditioner is restricted the cooling system becomes affected. If taken to extremes the critical pressure-temperature balance of the cooling coil can be changed. If they drop too low the cooling coils surface temperature can drop below the dew point temperature of the room. When this happens the cooling coil will begin to operate as a refrigerator rather than an air conditioner. Rather than simply cooling the air it will collect and hold moisture. The moisture will freeze onto the cooling coil where it will appear as ice.

The primary job of an air conditioner is to de-humidify, not refrigerate, the room air. By removing the moisture from the room air it gives us a feeling of comfort. To do this though the temperature of the cooling coil must always be higher than the room's dew point. If it is allowed to drop below the dew point the air conditioner will start to produce ice.

With this information in mind the following are a few problems that can result in your air conditioner icing up:

1. Dirty filter.
To avoid this replace or clean your filter every couple of weeks of the cooling season. If a smoker do it every week. To clean filter remove from air conditioner, wet thoroughly, and lay in bottom of a sink. Sprinkle detergent (laundry detergent works well) onto filter surface. Allow to sit for a few minutes. Add warm water to sink so that filter is completely covered. Soak for 15 minutes. Remove from water and rinse. Allow to air dry.

2. Dirty or blocked cooling coil.
An air conditioner requires regular maintenance. Usually every two or three years. Every year would be best, but this can be costly unless you do it yourself. During cleaning the cooling coil should be degreased and washed to remove accumulated dirt and debris. Degreasing is important to remove any coatings on the coil. If not done greasy residue can trap and hold air borne particles. They will build up on the coil and affect heat transfer. If left too long this can result in the cooling coil becoming partially blocked. This will produce a lower airflow.

3. Dirty or blocked condenser coil.
The condenser coil is the one at the rear of the air conditioner. Its job is to dissipate the heat that is being removed from the room. Just like the cooling coil it too must be cleaned every few years. Since the condenser is on the outside of the home it becomes exposed to a lot of dirt, pollen, and smog. Since airflow direction is from inside to outside it is the inside surface of the condenser that becomes dirty. Therefore to clean this part the air conditioner must be completely disassembled. If not cleaned regularly an airflow blockage here can even burn out the compressor. Before this happens though the lowering of airflow will affect the overall operation. This can result in the compressor efficiency dropping, the internal pressure-temperature relationships being affected, and the resultant production of ice on the cooling coil.

4. Inefficient compressor.
As describe above an inefficient compressor can cause icing up. If the compressor is not able to pump the refrigerant properly the cooing coil may not get cold enough to shut off the cold control. It can hover just above the cut off point. When this happens the cooling coil will begin to refrigerate. Ice on the cooling coil will result. If the compressor itself is at fault the air conditioner will have to be replaced. But note that many icing problems are misdiagnosed as bad compressors when they were actually one of the other faults discussed in this article.

5. Not enough refrigerant. Too much refrigerant.
Both scenarios can result in and icing condition. If your air conditioner was repaired recently suspect too much refrigerant. Mixed with an airflow problem this can be difficult to diagnose. If not repaired recently then suspect airflow problems before considering a refrigerant imbalance.

6. Outdoor temperature too low.
Icing can occur if the outside temperature falls below 60 Degrees Fahrenheit. If the outside temperature is too low the air conditioner pressure-temperatures can be affected. When the outside temperature falls the cooling coil temperature will also fall. So much that the coil will refrigerate the room air. This will result in the cooling coil beginning to produce ice. This problem is more prevalent in the fall. If it is hot during the day but cold at night suspect this problem as the cause of icing up. If this problem is suspected try running the air conditioner in the fan only position. Leave the re-circulating vent open. This will circulate the room air without cooling it, while bringing in a small amount of outside air during the night.

7. Oversized air conditioner.
If the air conditioner is too large for the room size icing up can result. If oversized the air conditioner can short-cycle. This condition is usually seen as the air conditioner starting and stopping every few minutes. Even though it runs almost constantly the air conditioner will give poor cooling. Use a sizing chart to determine what is the proper air conditioner size for that particular room.

8. Cold control not shutting off. If the cold control does not shut off the cooling coil surface temperature will drop below the room's dew point and begin to refrigerate. This will allow ice to build up onto the cooling coil.

9. Cold control bulb broken or loose. As in the previous paragraph this will result in the cold control not shutting off and ice to build up on the cooling coil. If this is suspected remove the front grille and inspect the bulb. If broken replace cold control. If bent, kinked, or not securely fastened suspect a problem here.

101 Easy Ways to Save Energy


All it takes is a few minutes each month, and you'll notice a difference - and make a difference!

Getting started

1. Do a home energy audit. This survey analyzes your home's structure, appliances and insulation. Home Inspections offers customers a comprehensive thermal imaging survey that provides a personalized report detailing specific ways to save energy throughout your home.

Heating your home

2. Change or clean your furnace filter once a month. Dust and dirt can quickly clog vital parts, making your furnace run harder and eventually break down.

3. Have your heating system inspected regularly - especially if it's natural gas. A $50-100 annual tune-up can help reduce your heating costs by up to five percent.

4. If you have a forced-air furnace, do NOT close heat registers in unused rooms. Your furnace is designed to heat a specific square footage of space and can't sense a register is closed - it will continue working at the same pace. In addition, the cold air from unheated rooms can escape into the rest of the house, reducing the effectiveness of all your insulating and weatherizing.

5. Install a programmable thermostat. If you use it to set back the temperature by 10 degrees for eight hours every night, you'll lower your heating bills by 10 percent. A $50 digital thermostat can pay for itself in energy savings in less than a year.

6. Don't set the thermostat higher than you actually want it. It won't heat your home any faster, and it will keep your furnace running longer than necessary.

7. Vacuum registers and vents regularly, and don't let furniture and draperies block the air flow. Inexpensive plastic deflectors can direct air under tables and chairs.

8. If your home has a boiler system, avoid covering radiators with screens or blocking them with furniture. It's also a good idea to add a reflecting panel behind radiators - you can purchase one at a home center or make one yourself with a plywood panel and aluminum foil.

9. If your home has electric baseboard heating, be sure to keep furniture and draperies away from the heaters, and leave at least a three-inch clearance under the heating unit.

10. Keep curtains and blinds closed at night to keep cold air out, but open them during the day to let the sun warm the room.

11. Avoid using space heaters, including electric, kerosene or propane models. Not only are they expensive to operate, they're also very dangerous.

12. If you have hardwood or tile floors, add area rugs to keep your feet warm.

13. If you'll be going on vacation, lower the thermostat to 55 degrees. This will save energy while preventing water pipes from freezing.

14. If you have a wood-burning fireplace, have the chimney cleaned and inspected regularly, and burn only fully dried hardwoods to produce the most heat output.

15. Check the seal on the damper by closing it off and holding a piece of tissue paper inside the firebox. If drafts blow the tissue around, repair or replace the damper.

16. When using the fireplace, turn down the furnace to 55 degrees. If you don't, all the warm air from the furnace will go right up the chimney, wasting energy and money.

17. Add fireproof caulk where the chimney meets the wall, inside and outside.

18. When the fireplace is not in use, make sure fireplace dampers are sealed tight, and keep the glass doors closed. If you never use your fireplace, plug the chimney with fiberglass insulation and seal the doors with silicone caulk.

Insulating your home

19. Check insulation levels throughout your house. Measure attic insulation with a ruler, and check behind switch plates for sidewall insulation.

20. Install more attic insulation. Upgrading from three inches to 12 inches can cut heating costs by 20 percent, and cooling costs by 10 percent.

21. Add pieces of batt insulation or spray foam to the rim joists - the area along the top of the foundation where it meets the exterior walls.

22. If your basement is unheated, install blanket insulation in between exposed floor joists.

23. Choose the new "no-itch" or poly-wrapped insulation products. They're much easier to handle and safer to work with - making them worth the extra cost.

24. Install additional attic insulation at right angles to the previous layer. You don't have to use the same type of insulation - it's fine to use batts or blankets over loose-fill, or vice versa.

25. When using loose-fill, be sure to distribute the insulation evenly. Any inconsistencies can reduce the insulating value.

26. While shopping for insulation, remember that R-value measures the amount of thermal resistance. The higher the R-value, the better the insulation.

27. Never cover attic vents or recessed light fixtures with insulation, and allow a three-inch clearance around chimneys and flue pipes to prevent overheating and avoid the risk of fire.

28. Have a leaky roof repaired and make sure your basement is waterproofed. Wet insulation is worthless.

29. Maintain your central air conditioner by cleaning the outside compressor with a garden hose (be sure to shut off power at the fuse or breaker first). Keep plantings at least two foot away for adequate airflow.

30. During late afternoon and early evening, turn off unnecessary lights and wait to use heat-producing appliances. It's also a good idea to shade south- and west- facing windows during the hottest part of the day.

31. Plant a tree. One well-placed shade tree can reduce your cooling costs by 25 percent. For maximum benefit, place leafy shade trees to the south and west, and evergreens to the north.

32. Use ceiling fans to help circulate air throughout the house, and make sure your attic is properly ventilated. A ceiling fan should run clockwise during the summer, and counter-clockwise during the winter.

33. Set the fan on your central air conditioner to "on" rather than "auto." This will circulate air continuously, keeping the temperature more even throughout the house and aiding in dehumidification.

34. Make sure your window air conditioner is the proper size. It's better to get one that's too small than too large - a larger unit will start up and turn off more frequently and won't do as good a job dehumidifying the air.

35. Don't judge the efficiency of your air conditioner by the sound of the fan shutting on and off. The blower will continue to circulate cooled air throughout your home up to 15 minutes after the compressor has stopped. (The same holds true for the furnace.)

36. Raise the thermostat to about 78 to 80 degrees whenever you go to bed or leave the house. A programmable thermostat will do this for you automatically.

37. If your home can't accommodate central air conditioning, try a whole-house attic fan. This device pushes hot air out through attic vents, lowering the temperature throughout your home about five degrees in less than ten minutes. Attic fans cost less than 25 cents per day to operate.

38. During the winter, remove window air conditioners and seal the windows with caulk and weatherstripping. You might also want to cover the central air compressor with a tarp to keep it clean.

Weatherizing your home

39. Seal doors and windows with caulk, weatherstripping and plastic film. An investment of $50 in weatherizing supplies can reduce heating costs by two to three times that much. Don't forget the basement windows!

40. Add foam gaskets behind all outlet covers and switch plates, and use safety plugs in all unused outlets. These are prime places for outside air to leak into your home. Be sure to shut off power at the fuse box or circuit panel first.

41. Check the exterior of your home for air leaks, especially around openings for water spigots, air conditioner hoses, dryer vents and gas pipes. Use caulk or expanding foam to seal spaces.

42. If your home has a large, single-pane picture window, use heavy draperies during the winter to help hold back cold air.

43. Reflective window film can help reduce heat gain during the summer, and it will keep furniture and carpets from fading.

44. Check window panes to see if they need new glazing. If the glass is loose, replace the putty holding the pane in place. Most types of window glazing require painting for a proper seal.

45. If drafts sneak in under exterior doors, replace the threshold. If that's not practical, block the drafts with a rolled-up towel or blanket.

46. Seal the edges of unused doors and windows with rope caulk. Don't seal them shut permanently - you might need quick ventilation or escape during an emergency.

47. Choose the right kind of caulk for the job. Use latex or acrylic caulk inside - it's easy to clean and more forgiving if you're a beginner. Silicone caulk is great for outside use because it lasts longer and seals virtually any type of surface.

48. Don't forget to weatherize the attic access. Secure batt insulation to the back of the hatch or door, and use weatherstripping to seal the opening.

Water Heating

49. Set the water heater temperature at 120 degrees - about halfway between low and medium. This will help save energy and prevent scalding, while keeping unhealthy bacteria from growing.

50. Install a water-saving showerhead. Don't worry - it won't reduce your water pressure. A family of four, each taking a five-minute shower a day, can save $250 a year in water heating costs by switching to a low-flow showerhead.

51. Fix leaky faucets, especially if it's a hot water faucet. One drop per second can add up to 165 gallons a month - that's more than one person uses in two weeks.

52. Use aerators on kitchen and bathroom sink faucets. If you have hard water, clean aerators and showerheads with vinegar regularly to reduce deposits and build-up.

53. Take showers, not baths. A five-minute shower will use about 7.5 gallons of hot water, while filling a bathtub can use up to 20 gallons.

54. If your water heater is more than 15 years old, install an insulating wrap to reduce "standby" heat loss. It's also a good idea to insulate hot water pipes where they're accessible.

In the kitchen

55. Use smaller kitchen appliances whenever possible. Microwaves, toaster ovens and slow-cookers can use 75 percent less energy than a large electric oven.

56. Vacuum the refrigerator coils about twice a year to keep the compressor running efficiently.

57. As your mother always told you, don't leave the refrigerator door open. Every time it's opened, up to 30 percent of the cooled air can escape. The same rule holds for the oven, too.

58. Keep the refrigerator temperature about 36-38 degrees, and the freezer at 0-5 degrees.

59. Don't overload the refrigerator or freezer. The cold air needs to circulate freely to keep foods at the proper temperature.

60. Make sure the refrigerator is level, so the door automatically swings shut instead of open. If the floor isn't level, use shims to prop up the front of the refrigerator.

61. Don't worry about placing hot leftovers in the refrigerator. It won't affect energy use significantly, and cooling food to room temperature first can increase the chance of food-borne illnesses.

62. Check the seal on your refrigerator door by closing it on a dollar bill. If you can pull the bill out easily, it's time to replace the gaskets. You can purchase a replacement kit from an appliance dealer or a home center.

63. Use your oven's self-cleaning feature immediately after cooking, while the oven is still hot. This will reduce a lengthy warm-up time.

64. Use lids on pots and pans to reduce cooking times, and don't put a small pan on a large burner.

65. Keep the grease plates under range burners clean to reflect heat more efficiently.

66. Run the dishwasher only with full loads, and use the air-dry cycle. If your dishwasher has a "booster" water heater, use it; this will heat the water to the 140 degrees recommended by manufacturers, while maintaining an energy-saving 120 degrees on your primary water heater.

67. Wash only full loads of clothes, and be sure to set the water level appropriately.

68. Use hot water only for very dirty loads, and always use cold water for the rinse cycle.

69. Clean the lint screen on the dryer every time you use the machine. A clogged lint screen can make your dryer use up to 30 percent more energy - and it can be a fire hazard.

70. Remove clothes from the dryer while they're still damp and hang them up. This will save energy, prevent static and reduce wrinkles and shrinkage.

71. Dry one load of clothes immediately after another. This will minimize heat loss, reducing warm-up and drying times.

Lighting your home

72. Switch to compact fluorescent light bulbs. These bulbs use 75 percent less energy than typical incandescents, and they last 10 times longer.

73. Look for a compact fluorescent wattage that's about one-third of the incandescent wattage you usually use.

74. Use lighting control devices like dimmers, motion detectors, occupancy sensors, photocells and timers to provide light only when you need it.

75. Keep lamps away from thermostats; the heat produced can cause your furnace to run less than needed or your air conditioner more than needed.

76. Dust light fixtures regularly. A heavy coat of dust can block up to 50 percent of the light output.

77. Use only a single bulb in a multi-socket fixture. Be sure to check the maximum wattage the fixture allows.

78. Replace an incandescent outdoor light or high-intensity floodlight with a high-pressure sodium fixture. The bulbs will last longer, use less energy, and handle temperature extremes better.

79. Use low-voltage lighting kits to light walkways, patios and decks. The soft light will also attract fewer annoying insects.

80. Decorate with pale colors on walls, ceilings and floors. Soft tones reflect more light, so you can use lower wattage bulbs and delay turning on lights until later in the day. Using high-gloss paint can help as well.

81. Read light bulb packages carefully. Watts measure the amount of energy needed; lumens measure how much light a bulb produces. Energy-saving bulbs produce more lumens per watt of electricity used.

82. Get rid of spare refrigerators or freezers. An extra appliance can add more than $100 to your energy bills every year, and it's a safety hazard for small children.

83. Keep outdoor hot tubs covered when not in use. If you have a pool, use a solar cover to use the natural warmth of the sun to heat the water.

84. Keep waterbeds covered with quilts or blankets to help retain their heat. You might also want to insulate the bottom with a sheet of rigid foam insulation.

85. Keep the garage door closed, especially during the winter.

86. If you need a new lawn mower, consider an electric model. They're less expensive to operate (about three cents of electricity per use), 75 percent quieter, and they significantly reduce toxic emissions.

87. Instead of air-polluting and expensive charcoal or propane, try an electric or natural gas grill. They're more economical and more convenient - you'll never run out of fuel.

88. Unplug any electrical device that's not being used. Many appliances, especially computers, televisions and VCRs draw power even when turned off.

89. Place humidifiers and dehumidifiers away from walls and bulky furniture. These appliances work best when air circulates freely around them. Be sure to clean the unit often to prevent unhealthy mold and bacteria from developing.

90. If your home has no sidewall insulation, place heavy furniture like bookshelves, armoires and sofas along exterior walls, and use decorative quilts as wall hangings. This will help block cold air.

91. When you take a vacation, don't forget to give your appliances a rest too. Turn off and unplug everything you can, set your water heater to the lowest setting and shut off the water supply to the dishwasher and washing machine.

Buying new appliances

92. Remember that it pays to invest in energy efficiency. In some cases, the money you save in energy costs can pay back the purchase price in just a few years.

93. Always read the Energy Guide label carefully, and make sure you're comparing "apples to apples." Energy use can range significantly even within a single brand.

94. Choose the capacity that's right for your family. Whether it's a furnace or a refrigerator, it doesn't pay to purchase a unit that's too large or too small.

95. In almost every case, a natural gas appliance is more economical to use than an electric model. The $50-75 price difference can be paid back in energy savings in less than a year.

96. Replace inefficient appliances - even if they're still working. An aging water heater or refrigerator could be costing you much more than you think. If your central air conditioner is more than 10 years old, replacing it with a high-efficiency new unit will cut your summer electric bills by about one-third.

97. Shop during the off-season. Many heating and cooling manufacturers offer significant rebates during seasonal sales promotions, and dealers may charge less for installation.

98. Investigate new technology carefully. Some innovations, like convection ovens or argon-filled windows, may save energy and make life more convenient; others, such as commercial-grade kitchen appliances, might be merely expensive cosmetic enhancements.

99. Look for the "EnergyStar" logo. This designation from the Environmental Protection Agency means that the appliance exceeds minimum federal energy- use standards, usually by a significant amount.

100. Don't forget to ask about warranties, service contracts, and delivery and installation costs.

101. Be sure to choose a reputable and knowledgeable dealer. A good dealer should be able to help you calculate energy savings and the payback period, and he or she should offer you a range of brands and prices.

The Five Point Air Conditioning Maintenance Checklist


When performing maintenance on your air conditioning system there are five things you should always check. By taking care of your air conditioner, you will extend its life by a number of years, improve it's efficiency, and ultimately save big money in the long run. So what are the five essential checks?

Check the filters and indoor coil

Remove the air filters and clean them. To do this, spray the filters on both sides with a kitchen antiseptic spray and then rinse well with warm water. Ensure you remove any lint and other dirt which has built up on the filters.

If you have a ductless air conditioner, you will also be able to see the heat exchanging coil behind where the filters are located. Ensure this is not clogged with dirt or covered in hairs, If it is, give it a gentle vacuum with the brush attachment in the same direction that the aluminium fins run.

Check and clean the coil and air outlets on the outdoor unit

Remove any obstructions around the outdoor unit such as weeds and dead leaves to improve air flow, then wipe down the air outlet on the front of the system. Check that you get good air flow through the system and that the coil is free of obstructions.

Check for good air flow from both indoor and outdoor units

Ensure you have plenty of airflow from the indoor unit. Poor airflow is a good indicator of a blocked coil or failing fan motor. If your air conditioner is struggling to output a reasonable amount of air, it may be time to book it in for a professional service.

Check for signs of rust or corrosion

If your air conditioner is starting to rust or show signs of corrosion, you will want to stop it progressing as early as possible. Minor rust caused from scratches etcetera can simply be painted over with a waterproof steel paint. Major rust or corrosion will require a professional to service the equipment as the system will usually require stripping down for the required repairs.

Check your system on both cooling and heating modes

Check your system on both cooling and heating modes. If your air conditioner fails to switch between the two different modes, it is usually a good indicator of a fault with the reversing valve which will require repair by a professional service engineer.

Why is it essential to maintain your air conditioning?

Put simply, the majority of air conditioning faults are caused by a lack of maintenance. Look after it properly and you will enjoy the benefits it has to offer. The key to keeping them working correctly is to simply keep them clean. Clean those filters and wipe off any dirt buildup on a regular basis and it will last for years to come.

If after checking the above your air conditioning is still performing poorly, you should call in a professional air conditioning service company as there is a good chance your system has a fault and is not operating correctly.

Too Much Air Conditioning Will Cause Serious Health Problems


Summer is here for people who live in the Northern Hemisphere. Air conditioning has become something that we can't live without. While we are enjoying the cool comfort it brings to us, have we realized that, like most other modern conveniences, air conditioning has its down sides, our health can be damaged if it is over used.

Nature has four seasons, human is part of the nature, only if the body operates harmoniously with the nature, we can live with health and longevity. 'The Yellow Emperor's Classics of Internal Medicine ', the bible of Traditional Chinese medicine, tells that summer is the season of thriving and blossoming. The body's circulation and metabolism are both moving fast. Body needs to remove the coldness and other wastes though letting out of some energy, such as sweating and evaporating. If you keep staying in the cool air conditioned environments, the body does not get change to accomplish its summer job, planting the seeds for future illnesses.

Traditional Chinese Medicine tells us that all the diseases are caused by six types of evil forces: they are: wind, coldness, dampness, dryness, hotness, and summer heat. Wind moves cold air, therefore, the number one and number two evils are both related to coldness. The most obvious problem can be seen of overuse of the air conditioning is that it aggravates the effects of arthritis and neuritis. It also causes trouble for those with sinus problem, causing the heads to become blocked.

Modern studies have shown that the people sheltered with the air conditioning are more susceptible to colds, flu and other minor problems. It has also been proven that the body experiences a certain amount of stress when it is forced to go from a really hot environment into a cool air conditioned one. The skin pores were wide open due to the heat, when the temperature suddenly and deeply dropped, the body has to quickly close them for self protection, this does not only add stress to the body, but also let in and seal the coldness inside, again, the seeds of the diseases.

The decision to use or not to use air conditioning is, of course, yours. Choosing pros and cons is also your own job. May be setting the temperature not below 78 degree Fahrenheit and stopping it once a while is a way to both get the benefits and avoid the detriments of air conditioning.

Go Green With Your Air Conditioning


Environmentally responsible consumers care a lot about their environmental impact. They select their home appliances carefully, to achieve a low emissions solution to their air conditioning needs.

Environmentally friendly air conditioning

A green air conditioner is designed to have minimal impact on the environment. That means:

  • It has a minimum carbon footprint, causing minimal pollution and carbon emissions

  • It's energy efficient, reducing demand on electricity generation from fossil fuels

  • It promotes good air quality in the home

Modern air conditioners are now designed with environmental considerations as very much a part of their design concepts. Big name, top of the range brands, like Mitsubishi air conditioners and Panasonic air conditioners, are based on company design policies.

These green air conditioners are all part of the new generation of air conditioning models. They're designed with the latest technology and a very strong emphasis on best practice in design and operation. The result has been to produce reliable, durable systems with full range of environmentally friendly features, high energy efficiency, and the complete spectrum of options for consumers.

Shopping for the right model

Shopping for green air conditioning can be environmentally friendly to your wallet, too and unit prices may come as a pleasant surprise. Prices for top line models are in bandwidths which can match any budget effectively.

It's worth shopping around and getting some advice from the professionals about your options with these advanced new models. You can also compare prices. There are always good deals to be found. A simple browse around a local website and a phone call can save you time and effort, allowing you to make an informed decision about your purchase.

How to find the best green air conditioning

  • Check energy ratings

  • Check features

  • Compare systems

  • Above all, ask when you need information.

Important: The new advanced air conditioner units have a lot of new features, and you will have a few questions you need answered. Salespeople in air conditioning are experts, fully trained on the whole range of their stock, and they know their systems very well. They can take you through the issues and decision process one step at a time, and clarify any issues you may have.

How to buy the right green air conditioning for your home

The right green air conditioning is easy to define:

  • The system meets all your needs

  • The system is tailored to meet your space requirements

  • It's clearly energy efficient, and well rated

  • If you're looking for a ducted air conditioner, a wall mounted unit, a window or a multi split air conditioner, the design complements your home.

  • The system has a good clear cut warranty and servicing component.

Your new green air conditioner will be a great improvement, adding comfort to environmental peace of mind.

Air Conditioning Coolant Change


Big changes came to the air conditioning industry on Jan. 1, 2010 to mitigate the deterioration to the ozone through the International Green Treaty. Air conditioners now have a new set of standards to stay compliant. The main change is the coolant the EPA now accepts.

Chlorine is the main substance that air conditioners use to cool which also causes ozone depletion. Causing significant damage, chlorine has been used as a coolant in nearly all air conditioning units since the 1970's. The chemical is known as R-22. Currently, the government has demanded a phase-out which means air conditioner repair companies and manufacturers can no longer use R-22.

The air conditioner repair companies will replace R-22 with R-410A which has no chlorine and no effect on the ozone. If you are still using R-22 as your air conditioning coolant, you should start thinking about a switch. The longer you wait the more expensive it will get because parts related to R-22 air conditioners will be harder to obtain.

Switching is not as bad as it sounds. In the last five years, energy costs have soared about 50% of what they once were. If you update your air conditioner to the new standards, you can save up to 45%.

There are also tax incentives and manufacturer rebates to keep in mind. You can usually find a great rebate through your reputable air conditioning company as well as more information on the latest tax incentives. If you would like to research before contacting an air conditioning company, a good place to start is online through the BBB and your government databases for tax incentives.

After the completion of your research (checking you coolant and which rebates and tax incentives are applicable) make sure you contact a reputable air conditioning company for installation. If the installation is improper your air conditioner can be damaged. The shoddy installation can also cause your air conditioner to use more energy than it should, which can reverse a portion your 45% savings. Once the new installation is in place, keep it well maintained and you can save yourself a great deal of money.

The last step to get the most out of your air conditioner is to make sure you obtain proper installation. A key part of upgrading your unit is to get the most out of it and improper and shoddy installation can quickly defeat this purpose. Keep it well maintained as well and you will see a significant reduction in your energy bills. Don't wait until its 2010, start looking for new and more energy efficient cooling solutions today.

Your Air Conditioner Needs Regular Maintenance Too


Just like you take yourself to the doctor each year for your annual physical or take your car to the mechanic for regular maintenance, your air conditioner needs to be treated with some tender loving care. While they are designed to generally be tough, these machines will work a lot better if they are well taken care of. The average air conditioner in AZ looses about 5% of its efficiency per each year you run it if you do not take the time to make it run better. There are things that you as the homeowner can do to help keep your AC unit in good shape.

The number one important thing you need to do for your AC unit is to change the filter on a monthly basis. Nothing could be easier to do to keep your unit running at maximum performance. A dirty filter blocks the necessary air flow that your air conditioner needs to force cold air into your home. If you don't change it your unit might start pumping out warm air or might even stop working altogether. Another important step is to clean out the drain. Simply put a cap on the end of the drain and use a vacuum to such out the dirt. Take the cap off after you are done to avoid a catastrophe. While you can do this throughout the year, call in a professional to use his high pressure vacuum to really get in there and clean it good. You should also clean your Scottsdale air conditioning coils. Make sure the power has been disconnected first! Make sure you use gloves and safety glasses and spray the cleaner, that you can get at your local hardware store, directly onto the coils. After a while rinse it thoroughly with your hose.

The rest of the job should be left to the professionals. Run your air conditioner for a little bit in the spring, before the heat of summer hits. This will let you know if there are any problems now that can be addressed when the technician shows up. You will want to have your maintenance for your air conditioner scheduled for the spring rather than waiting until the last-minute when the weather starts to get hot. The tech will probably check your refrigerant levels and refill as needed. They will also check all of the electrical components, the condenser and the filters. If your evaporator and condenser coils are dirty they will clean them. They will also calibrate your thermostat so you are getting exactly what you want in terms of temperature from your air conditioners in Phoenix.
