Best Answer

R-22 (Freon 22) is used in a lot of home air conditioners. In the mid-1990s, manufacturers started switching to R-134a refrigerant. The manufacturers' data plate on the unit provides information about what type of refrigerant is used in a given installation. Manufacture of Freon 22 is being phased out and it is extremely expensive.
