IMPACT ON HOMEOWNERS WITH OLDER AC UNITS
WILL YOUR AIR CONDITIONING SYSTEM NEED TO BE REPLACED BY 2020?

AQM wants to help clear the air about Freon and older air conditioning systems. Here’s what you need to know.
NEW REFRIGERANT REGULATIONS IN EFFECT FOR 2020
For decades, Freon, also known as HCFC-22 and R-22, was the main refrigerant chemical used in residential air conditioning units and heat pumps. To help protect the ozone layer, the EPA has mandated that the production of Freon be stopped by January 2020.
The good news is that new air conditioning systems made since 2010 no longer rely on Freon. Most newer AC units use a refrigerant called R410A, or Puron. This chemical is an HFC (hydrofluorocarbon), but has been shown not to harm the ozone and, since 2015, has become the standard for residential air conditioning.
IMPACT ON HOMEOWNERS WITH OLDER AC UNITS
Freon is really an environmental hazard if it leaks or is disposed of improperly. Freon-based HVAC units that still function properly don’t need to be replaced now either. Beginning in 2020, Freon will no longer be produced or imported, but limited amounts will still be available. Older systems can be serviced or recharged with refrigerant using stocks of HCFC-22 until the 2020 date. After that, technicians will need to source recycled Freon to keep an old cooling system running.
Here’s a quick timeline to clarify the important dates in coming years for homeowners with air conditioning units made before 2010:
Up to 2020 – Older systems can be serviced with stock Freon.
2020 – The end of Freon production and importation.
After 2020 – Older systems can be serviced with recycled Freon.
How the new refrigerant regulations regarding Freon will affect homeowners starting in 2020 depends on the age of their air conditioning unit.
Retrofitting Older AC Systems
If the coils are compatible with R410A refrigerant, HVAC technicians can replace the outdoor unit without needing to modify other components throughout your house. This solution can be expensive, but it will keep your current AC system working. Plus, switching to R410A may actually make it more energy efficient. Routine service is more important for these retrofitted systems to prevent leaks and any harmful effect on the environment.
