Legacy & Phased-Out Refrigerants

4 refrigerants in this category. These refrigerants are ozone-depleting CFCs and HCFCs whose production has ended under the Montreal Protocol and the Clean Air Act: R-12 and R-502 in 1996, R-22 and R-123 for new equipment in 2010 and 2020. They remain in older equipment, and supply now comes from reclaimed stock. Each page links to the usual retrofit or replacement refrigerant.
