Alternatives to R-22 Refrigerant

Today, manufacturers of residential air conditioning systems offer AC equipment that uses ozone-friendly refrigerants. For servicing existing equipment, R-22 is still available and will continue to be available for 10 years or more.

The EPA has reviewed a variety of substitutes for R-22. You can see these alternatives to R-22 on the EPA website.

A popular substitute for R-22 is R-410A, a blend of hydrofluorocarbons (HFCs). It is manufactured and sold under various trade names, including Puron®, Forane® 410A, GENERATION AZ-20®, and SUVA 410A. It does not deplete the ozone layer but, like R-22, its manufacturer does contribute to global warming.  R-407C, another acceptable substitute for R-22, is used in some European residential air conditioners.
