A2L Refrigerant Training

A2L mildly-flammable refrigerants will be phased into the HVACR industry to replace Hydroflourocarbon (HFC) refrigerants in the residential marketplace. While mildly-flammable refrigerants are seemingly better for the environment, the handling and safety precautions that go along with their use are different than HFC or CFC refrigerants.
This A2L Refrigerant Training is designed to help HVAC professionals prevent ignition while working with A2L refrigerants and educate staff on the best safety practices to keep staff and clients safe. Each student enrolled will receive the full course as well as a workbook and a certificate upon course completion.
