The Next Generation of Cooling Refrigerants. A refrigerant is a liquid that is stored in your AC coils, which help cool and dehumidify the indoor air. If we didn’t have refrigerants, we wouldn’t have air conditioning. Over the years, 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, it will no longer be legal to produce R-22 due to its damage to the environment. Introducing R-410A To decrease environmental impacts, all Lennox® products are now compatible with the new R-410A AC refrigerant. R-410A is EPA-recognized and is free of chlorine, making it ozone-friendly. You can feel at ease using this refrigerant in Saint Peters because it’ll help make your cooling system perform efficiently, reliably and quietly, and offer the same cool comfort in the warmer months. Additional Considerations If your AC or heat pump was manufactured before 2010, it may not be R-410A-compatible. You might think about upgrading your cooling system before R-22 is ultimately phased out. The old refrigerant will become hard to find in the next few years, costing you more to operate your system effectively. The Lennox products we offer at C-N-O Comfort Zone work with R-410A, so you can rest assured 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.
