While refrigerant regulations are important, there are other rules and regulations being implemented that HVACR contractors need to understand.

In the first installment in this series, we talk with Don Gillis who is a technical trainer with Chemours. Gillis travels the country providing top-notch training on the refrigerant transition. We ask Gillis how contractors can safely recover and recycle A2L refrigerants.

The reclamation of HFC refrigerants is now essential so that existing HVAC systems, and systems that can be sold through 2025, can be serviced for the next couple of decades.
