Regular maintenance is very important to keep an air conditioner in good shape and give optimum, hassle-free performance.

Depending on the usage of the air conditioners it usually loses about 5 to 10 % of its efficiency every year. If you purchase a 12 SEER unit and use it for 3 - 4 years, its capacity will equate that of a 10 SEER unit. The efficiency lost can be retrieved through maintenance to a large extent.

With regular tuning and cleaning, an air conditioning unit will retain its operational efficiency. So instead of waiting for a failure and incurring additional repair costs and heavy electricity bills one should get the unit serviced. The most important element that requires a tune-up is the air filter.

A system that is low on coolant, will cost more to operate. If your air conditioner has a leaking system, the first thing you should do is to fix the leak. Freon, a chlorofluorocarbon, damages the earth’s protective layer, which is the ozone layer.
