For a home, contractors select from specific sizes based on the amount of square footage the home has.One reason for contacting an expert in Air Conditioning in Phoenix Arizona is maintenance for an existing system.

Most people prefer the end of winter, but certain climates, like that in Phoenix, may demand more from the AC.

The principles behind an air conditioner are reasonably simple. The first thing to remember is that an AC is actually a heat exchange system. This means it collects heat from the building and transfers it outdoors. It uses a chemical refrigerant for this task. The refrigerant starts out as a gas which is then condensed into a liquid. The state change to liquid makes the refrigerant very cold. This cold cycles through the evaporator coil where it is transferred to the fins for release into the home. As the chill leaves the refrigerant, it turns into a gas again. Because of temperature variances, the refrigerant is able to collect heat from around the coil to transfer outdoors.
