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. 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 due to its negative effects on 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 is free of chlorine, so it’s ozone-friendly. You can feel good about using this refrigerant in the Upper Rio Grande Valley because it’ll help make your cooling system work efficiently, reliably and quietly, and deliver the same cool comfort in the warmer months. Additional Considerations If your AC or heat pump was made anytime before 2010, it may not be R-410A-compatible. You probably should look into upgrading your cooling system before R-22 is ultimately phased out. The old refrigerant will become rare in the next few years, costing you more to run your system effectively. The Lennox products we offer at Cytech Heating & Cooling work with R-410A, so you can be sure we have an AC or heat pump more suited to your needs. Be sure to 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.
