Cooling Refrigerants of the Future. Refrigerants are liquids stored in your air conditioner’s coils that cool and dehumidify indoor air. If there weren’t refrigerants, there wouldn’t be air conditioning. 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, it will be illegal to produce R-22 due to its damage to the environment. Introducing R-410A To reduce environmental impacts, all Lennox® products are now engineered to work with the new R-410A AC refrigerant. R-410A is EPA-recognized and doesn’t contain chlorine, which means it’s ozone-friendly. You can feel good about using this refrigerant in the Main Line because it’ll help make your cooling 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 made before 2010, it may not be R-410A-compatible. You may want to think about upgrading your cooling system before R-22 is ultimately unavailable. The old refrigerant will become hard to find in the next few years, costing you more to use your system effectively. The Lennox products we offer at O'Brien Heating & Air Conditioning work with R-410A, so you know we have an AC or heat pump more suited to your needs. You should also refrain from using”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.
