Cooling Refrigerants of the Future. An air conditioner or heat pump counts on its refrigerant to cool and dehumidify the air before it’s streamed back into your home. This liquid is contained within the coils of a cooling system, but one of the most widely used refrigerants used for a very long time – the R-22 (Freon) is now being replaced because of environmental concerns. In fact, this phase-out was mandated by the U.S. Environmental Protection Agency through the Clean Air Act. By 2020, the production of R-22 will end all together. Introducing R-410A R-410A is EPA-recognized, chlorine-free and ozone-friendly. R-410A will cool your home without damaging the environment. Additionally, Lennox’s most efficient systems are made to use this AC refrigerant, which can help your system perform efficiently. The same Lennox systems are known for dependability, quiet operation and improved dehumidification, so you’re sure to stay comfortable. Additional Considerations At PWA Heating & Cooling Inc in Plainfield, our cooling offerings can work with R-410A. If your system was installed before 2010, you may want to consider replacing your cooling system now, before R-22 is hard to find. Some manufacturers sell alternate refrigerants such as R-407C, R-438A and R-422, however, they may not work with an R-22 AC or heat pump and could compromise your system’s performance.
