Air Conditioners



Welcome to airconditionmission3.com where you can find all things related to the world of Air Conditioners. Air conditioning. What a lifesaver. It has made the suburbs possible. Manufacturing from the north to the south occurred because plants could be built and people could work in them without collapsing from the heat. Its cost at one point, however, drew one scientist, William Schockley the co-inventor of the transistor, to move his research facilities to California, to what later became known as Silicon Valley. There he did not have to put air conditioning in his building. Even when air-conditioning was purposely avoided, it had an impact. So it started out as a way of making people comfortable. Right? Well, not exactly. In 1882, thanks to Thomas Edison, the first electric power plant opened in New York making it possible for the first time to have an inexpensive source of energy for residential and commercial buildings. And by 1889, central station refrigeration was used in large cities to preserve foods and documents. It was well known that a cool surrounding could preserve foods and other perishables for a long time. But what was not well known was how humidity and heat were related. Then in 1902, Willis Carrier built the first air conditioner to combat humidity inside a printing company. Controlling the humidity in printing companies and textile mills was the start of environment management.



Service Your Air Conditioner for Summer Comfort 05/21/12 We all know that we can pay our auto mechanics a little now for routine service, or pay them a lot later for a major repair. The same idea holds true for your air conditioner or heat pump. If you don't service your air conditioner or heat pump regularly, you'll find yourself uncomfortable and broke. In this article the term air conditioner will apply to a heat pump or a standard air conditioner. Both benefit equally from annual service tune-ups. An air conditioner is a very tough piece of equipment. It is engineered to withstand all sorts of abuse and keep on running. This is great in most respects, but it can lead to complacency about maintenance. Like a car, air conditioners need regular tune-ups to run properly. Without regular maintenance an air conditioner looses about 5% of it's original efficiency for each year of operation. This means that the 12 SEER unit that you bought just a few years ago may be functioning like a 9 SEER unit today! The good news is that you can recover most of that lost efficiency through regular maintenance. Studies show that with regular tune-ups a unit will maintain up to 95% of it's original efficiency. This means that the cost of an annual tune-up is recovered very quickly in savings on your monthly electric bill and reduced repair costs. A properly serviced air conditioner will also do a better job of dehumidifying your home. Many local air conditioning firms offer special prices at this time of the year. Some even offer annual service programs that insure that you will be reminded of the need to service the unit at the beginning of the cooling and heating seasons. The service check should include cleaning the condensing unit coils, checking the amp draw of the compressor, oiling the fan motors, checking that belts are well adjusted, and checking the system operating pressures and temperatures against the manufacturers specifications. One of the most important items to check is the coolant level (commonly know as Freon) in the air conditioner. A system that is only 10% low on coolant will cost about 20% more to operate! The Air Conditioning Contractors of America (ACCA) recommends that coolant levels be checked every year. If your unit is low on coolant, and more must be added, there are new laws governing its use. Freon is a chlorofluorocarbon (CFC) that will damage the Earths protective ozone layer if released into the atmosphere. The laws governing CFC's now do not allow your air conditioner contractor to add Freon to a leaky system. They are first required to find and fix the leak in the system. Don't ask them to violate this law as they may loose their license if they are caught doing this. There are some things in addition to yearly tune-ups that you can do to help ensure a high level of comfort and proper system operation. First, buy good filters and change them regularly. Next, keep bushes and other materials away from the outside unit of your air conditioner. Another good idea is to avoid closing supply air outlets in your house. In almost all cases, closing supply outlets is harmful to the operation of the overall system. All equipment, even the most reliable, needs routine maintenance. Complicated equipment like today's air conditioners benefit in many ways from annual service. They recover much of their lost efficiency, they are less likely to suffer a major break down, they have a longer life span, they increase your comfort, and they operate for less money.
