R-22 is the most widely used HCFC refrigerant for HVACR applications, such as residential air conditioning, refrigeration, and other cooling applications. Although R-22 has been a good solution for many different applications, it is classified as an HCFC and is subject to phase-out, according to the Montreal Protocol international treaty and the Clean Air Act in the United States.
In the US, the Clean Air Act has met the requirements of the Montreal Protocol by limiting consumption of HCFC, including R-22, through a series of phase downs through 2030. Each step reduces R-22 consumption by reducing or eliminating R-22 in different market segments. As part of this phase-down, R-22 has not been permitted for use in new OEM HVACR equipment since 2010.
The EPA recently issued the final HCFC Rule, which covers the 2015 to 2019 R-22 production allowances. After 2019, importation or production of R-22 will not be permitted in the United States, however, it can still be purchased, used, and sold from existing inventory and reclaim. R-22 is still the best refrigerant for R-22 equipment, and R-22 users should review all their options before making any major changes to their R-22 equipment.
If an R-22 user needs to retrofit, Forane® 427A is your best option for most R-22 equipment. To learn more about our EASY RETROFIT™, Forane® 427A, and our other retrofit refrigerants, visit our Forane® 427A (R427A) page for help with your selection.
