The Next Generation of Cooling Refrigerants. 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. 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 be illegal to produce R-22 as a result of 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, which means it’s ozone-friendly. You can feel good about using this refrigerant in Rapid City because it’ll help make your system perform 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 might look into upgrading your cooling system before R-22 is completely 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 Street Heating & Sheet Metal Inc work with R-410A, so you can be sure we have an AC or heat pump more suited to your needs. Additionally, avoid”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.
