HC (A3) & HFO(A2L) – Low GWP Refrigerant Training

As the HVAC/R industry evolves, more energy-efficient and environmentally friendly refrigerants are being introduced.  These Low-GWP refrigerants are considered flammable (A3) or slightly flammable (A2L).  Proper handling of these refrigerants is important, which is why Mainstream Engineering offers a complete A3/A2L low-GWP training for EPA 608-certified technicians.
