There has been a flurry of legislation passed at the state and federal level, which will lead to the phasedown of high-GWP HFC refrigerants such as R-410A. Some of the new low-GWP refrigerants designed to take the place of R-410A, such as R-32 and R-454B, are mildly flammable (A2L), and there may be concerns about handling these types of refrigerants.

At a recent webinar (below) hosted by AHRI, Jason Obrzut, director of industry standards and relations for ESCO Group, sought to allay those concerns by discussing how servicing A2L equipment will not be that much different than working on R-410A systems.
