Has R-22 refrigerant been discontinued?

Yes, R-22 refrigerant, commonly known as Freon, has been discontinued due to its harmful environmental impact. The production and importation of R-22 were phased out in the United States on January 1, 2020, as part of efforts to reduce substances that deplete the ozone layer. While recycled and reclaimed R-22 can still be used for existing systems, it is recommended to upgrade to newer, more environmentally friendly refrigerants and systems.
