The United States has committed to reducing ozone-depleting substances to help protect the environment. As part of this commitment, chemical refrigerants made from hydrochlorofluorocarbons (HCFCs) are set to be completely phased-out from use by January 1, 2020—only a few months away.
What does this mean for you? If you have an older air conditioning system that uses R-22 refrigerant, a.k.a. HCFC-22, it means plenty. For many decades, R-22 was the most common refrigerant blend used in air conditioning equipment. Newer AC models built since the start of the phaseout use an ozone-safe refrigerant blend call R-410A. You can check which type your air conditioning system uses by looking on the metal plate on the back of the condenser cabinet. It will have either R-22 or R-410A clearly marked.
