The HVAC industry is undergoing a major transition to A2L refrigerants caused by the U.S. Environmental Protection Agency phasing down the greenhouse gas refrigerant hydrofluorocarbons (HFCs), moving manufacturers to use refrigerants with low global warming potential (GWP) instead.

A new refrigerant comes with plenty of questions for both HVACR contractors and homeowners. The ACHR NEWS is enlisting industry experts to help educate HVACR contractors on what are the facts of A2L refrigerants while also identifying fiction about the products.

In part two of this series, we again bring in Chemours technical trainer Don Gillis to help us out. The HVACR industry veteran Gillis travels the country providing top-notch training on the refrigerant transition.

The flammability issue is one that is talked about often. We ask Gillis what steps contractors and technicians should take to mitigate the risk of ignition when working with A2L refrigerants.
