R22 refrigerant has been used for years in central air conditioners, heat pumps, mini-splits and other refrigeration equipment. It has been deemed hazardous to our environment and is being phased out of production.
R22 is a greenhouse gas that dangerously contributes to the depletion of the Earth's ozone layer. Since we rely on the ozone to absorb harmful UV radiation, it's very important to pinpoint and eliminate the use of greenhouse gases whenever possible. The R22 phase-out is occurring in accordance with the U.S. Clean Air Act and the Montreal Protocol on Substances that Deplete the Ozone Layer.
To save money on future repairs - and do your part for the environment - consider replacing your air conditioner sooner rather than later. Newer HVAC systems use acceptable refrigerants with the added benefit of increasing the resale value of your home.
