How Does Air Conditioning Work?

The air conditioner in a central heating and cooling system provides cool air through ductwork inside your home, by providing a process that draws out the warm air inside, removing its heat. Your air conditioning unit uses chemicals that convert from gas to liquid and back again quickly. These chemicals transfer the heat from the air inside your property to the outside air.

How often should air conditioning be serviced?

Heating and air conditioning equipment, no matter what kind you have, should be inspected, cleaned, and serviced at least once a year. The best scenario is to have the heating system checked in the Fall and the air conditioning checked in the Spring.

how long should my air conditioning run?

In mild weather, a correctly sized and functioning AC will run in cycles of about fifteen minutes each. This is approximately two to three times per hour. If your air conditioner runs for less than ten minutes at a time instead, then it’s probably oversized—too big for your home.

How long does air conditioning freon last?

Air conditioning doesn’t “use up” refrigerant. So you should never need to recharge your air conditioner with more Freon—unless there’s a leak.
