The U.S. Environmental Protection Agency (EPA) has issued a final rule to ban the use of HFC-134a as a motor-vehicle air-conditioning system refrigerant starting with model-year (MY) 2021 new vehicles. The rule would not apply to the use of HFC-134a in vehicles already in use or the ability to continue servicing those vehicles with the refrigerant.
Although HFC-134a was approved for use years ago, other chemicals have now been identified by the EPA as being more environmentally friendly substitutes to chlorofluorocarbons that deplete the ozone layer.
