A2L Refrigerant Servicing Best Practices

The refrigerant transition is underway, and HVACR service technicians find themselves at the leading edge. As the commercial refrigeration and AC industries move from high-global warming potential (GWP) hydrofluorocarbon (HFC) refrigerants to lower-GWP alternatives, mildly flammable A2L refrigerants are viewed as viable alternatives. But the technician community is largely unfamiliar with A2L servicing requirements and has many questions that need to be answered. This article covers the emergence of A2Ls and reviews key servicing best practices.
