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 housed within the coils of your home’s cooling system, but one of the most widely used refrigerants that’s been in use for many years – the R-22 (Freon) is now being phased out due to environmental concerns. In fact, this phase-out was mandated by the U.S. Environmental Protection Agency through the Clean Air Act. By 2020, R-22 will no longer be in production. Introducing R-410A Recognized by the EPA, R-410A is a chlorine-free and ozone-friendly refrigerant. R-410A will keep your home cool without hurting the environment. Even better news, Lennox’s most highly efficient systems are engineered to use this AC refrigerant, which can help your system operate efficiently. The same Lennox systems are known for dependability, quiet operation and better dehumidification, so you can stay comfortable. Additional Considerations At Custom Air Systems Inc in Port St. Lucie, our cooling models can work with R-410A. If your system was made before 2010, you may want to consider replacing your cooling system now, before R-22 is scarce. Some manufacturers offer 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.
