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.

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).

R22 is a greenhouse gas. Any time R22 escapes into the atmosphere, it contributes to the depletion of the ozone layer. However, in an A/C unit that’s in good working order, R22 is contained inside of the unit, and there is nowhere for it to go.

Mar 13, 2025 · R22 is a controlled substance, meaning it’s illegal to release it into the air or throw it away because it contributes to ozone depletion and climate change. If you’re replacing your AC or switching refrigerants, a licensed HVAC technician must properly recover and dispose of R22.

Forane ® 22 refrigerant (R-22) is used in a broad range of applications, including residential and commercial air conditioning, refrigeration, chillers, room air conditioning, heat pumps, transport refrigeration, and other comfort cooling and refrigeration applications.

Jun 22, 2018 · R-22 refrigerant, or Freon, was and still is one of the most popular refrigerants used in the world. R-22 is an HCFC refrigerant and can harm the Ozone layer. It was originally invented by a partnership with General Motors and the DuPont company all …

So, what exactly is this refrigerant R22? Commonly known as HCFC-22, this colorless gas is a minor player with a major impact. Used predominantly in air conditioning systems, R22 has some unique characteristics that set it apart.
