The Next Generation of Cooling Refrigerants. Refrigerants are liquids stored in your air conditioner’s coils that cool and dehumidify indoor air. Without refrigerants, air conditioning would not be possible. For a long time, the most common AC refrigerant was R-22 (Freon), but in 2012 the U.S. Environmental Protection Agency (EPA) mandated the phase-out of R-22 through the Clean Air Act. By 2020, R-22 will no longer be legal to produce because of its destructive impact to the environment. Introducing R-410A To reduce environmental impacts, all Lennox® products are now compatible with the new R-410A AC refrigerant. R-410A is EPA-recognized and contains no chlorine, so it’s ozone-friendly. You can feel great about using this refrigerant in Ontario because it’ll help make your system work efficiently, reliably and quietly, and provide the same cool comfort in the warmer months. Additional Considerations If your AC or heat pump was built anytime before 2010, it may not be R-410A-compatible. You probably should investigate upgrading your cooling system before R-22 is completely unavailable. The old refrigerant will become rare in the next few years, costing you more to operate your system effectively. The Lennox products we offer at Stan's Heating, Inc work with R-410A, so you know we have an AC or heat pump you can better rely on. You should also steer clear of”alternate refrigerants that claim to work in R-22 systems. These include R-407C, R-438A and R-422, all of which can actually compromise your system’s performance.
