How Freon Works

There is a system of coils and compressors in your AC unit. The AC compresses the R-22 gas, making it very hot. When this gas moves through the coils, it cools down to a liquid form. In this form, the cooled R-22 absorbs the heat from the outside air, then pushes the cold air out. It is a constant cycle of hot air in and cold air out that provides comfort in your home and car.


Every AC unit needs a refrigerant to cool the air. When the coolant leaks, the AC stops blowing cold air. Even worse, these coolant leaks are harmful to the ozone. Most air conditioner’s manufactured after 2003 do not use Freon as the refrigerant, as strict regulations have been placed on the use of Freon which makes it more expensive to maintain.


Not every problem related to an air conditioner that only blows hot air is related to the refrigerant. You may need to change the filter or install a better thermostat. There is no reason your refrigerant should deplete on its own. If the Freon or other cooling agent is low, you probably have a leak. You should always call an HVAC technician to find and fix the leak before adding more coolant.

Prepare your system for the warm summer weather soon to arrive.
