R-22 was a commonly used refrigerant that is being phased out because of its harmful impact on the ozone layer. If your HVAC system uses R-22, don’t panic — you can still use and maintain your system as normal.

Chlorodifluoromethane or difluoromonochloromethane is a hydrochlorofluorocarbon (HCFC). This colorless gas is better known as HCFC-22, or R-22, or CHClF. 2. It was commonly used as a propellant and refrigerant.

R22 refrigerant, or R22 Freon, is used in a number of AC systems built before 2010. It was discovered that the chemicals that makeup R22 are detrimental to the ozone layer. The Environmental Protection Agency (EPA) launched a 10-year plan in 2010 to phase out ozone-depleting substances.

May 31, 2024 · Since January 1, 2020, R-22 or Freon® has been illegal to import or manufacture in the United States. Find out what you need to do if your heating and cooling system was made before 2010.

May 21, 2018 · After 2020, any air conditioning or heat pump system using R-22 that requires servicing will have to depend on potentially expensive R-22 stockpiles or reclaimed refrigerant. The new ban on R-22 won't affect homeowners that want to continue to utilize their functioning R-22 air conditioning systems.

Mar 13, 2025 · As of 2020, R22 has been phased out in the U.S., meaning no new supply is being produced — only recycled or reclaimed stock remains. This has driven the price up to $200–$600 per pound, with a full recharge potentially costing $1,500 or more. So, what’s your best move?

May 23, 2024 · R-22 (also known as HCFC-22) is an ozone-depleting refrigerant which has been widely used in home air conditioning systems and its supply is now being phased out in response to the Montreal Protocol.

May 21, 2019 · On January 1, 2020, there will be no more production or import of R-22. By now, almost everyone in the HVAC-R industry should be well-aware: The R22 refrigerant phase out in the U.S. has almost reached completion.

R-22 refrigerant is a chemical used in older AC units and heat pumps to cool your home. You may know it as Freon®. On January 1, 2020, the U.S. Environmental Protection Agency (EPA) banned the production and import of R-22 due to its notably detrimental effects on the ozone layer when it's discharged into the atmosphere.

R22 refrigerant is also called as Freon 22 or simply R 22 Freon. R22 is the short name for the halocarbon compound CHClF2 (monochlorodifluoromethane), which is used as the refrigerant. Refrigerant R22 is hydroclhorofluorohydrocarbon (HCFC).
