How can I tell if my air conditioner uses freon?

Tuesday, July 23, 2019

Freon is a registered trademark of The Chemours Company. But it has become a common name for the fluorocarbon refrigerant R-22, like the way brand names “Kleenex” and “Xerox” were appropriated by the public to mean any similar products.

    You need to closely examine the sticker (data plate) on the side of the outdoor unit (condenser) of your heat pump or air conditioner looking for the words “factory charge,” “contains,” or “refrigerant” in one of the boxes. If your system uses “Freon,” it will say “R-22,” “HFC-22,” or simply “22” next to it. 

    If you have the newer refrigerant, it will be “R-410A” or “HFC-410A.” For more details and photos of examples, see our blog post How can I tell if an air conditioner uses R-22 or R-410A refrigerant?
