How does an air conditioner work?

An air conditioner doesn’t actually add coolness to a home, but rather removes heat from the air indoors and transfers it to the outdoor air. Heat from the indoor air is extracted when it passes across a cooling coil located in the indoor AC unit. When the hot air indoors passes over the cold evaporator coils, a refrigerant inside the coils absorbs the heat. In order to maximize efficiency, the air conditioner coverts the gas inside the coils back to a liquid by placing it under high pressure.

The heat created from this compression is sent outdoors through a set of condenser coils and a fan. This endless cycle continues until the optimal temperature is reached inside. Frank will ensure your system always reaches the optimal temperature:

There are two activities happening in an air conditioner. First, the refrigerant inside is chilling the indoor air creating a gas. This gas is being compressed, cooled, and then converted back to a liquid. Once this happens, the heat is released to the outside air and the inside air remains cool.
