If you work in the HVACR business, you have probably heard that the US Clean Air Act and the Environmental Protection Agency (EPA) are calling for the gradual elimination of all ozone-depleting refrigerants. This includes the most commonly used refrigerant today, HCFC R-22, which is found in residential and commercial systems everywhere. The regulations currently state that there will be no production or importing of HCFC R-22 beginning in 2020.
