Advanced Environment-Friendly Refrigeration Training Added to HVAC Program
February 18, 2025
The HVAC&R Certificate program at Franklin Cummings Tech has introduced advanced refrigeration training techniques to align with new environmental regulations requiring the use of energy efficient A2L refrigerants, such as R-454B and R-32, for residential and light commercial HVAC systems.
Adoption of these refrigerants, with a Global Warming Potential (GWP) of 700 or less, is part of an industry-wide shift to reduce greenhouse gas emissions and ozone depletion.
Technical trainers from Johnstone Supply of Waltham visited campus today to conduct a training session for HVAC students and faculty about the environmental benefits of the new refrigerants and the unique handling and safety procedures associated with A2Ls, which differ from traditional A1 refrigerants like R-410A. Students learned about the distinctive safety features of A2L refrigerant cylinders, including their light green-gray and red-topped design, left-handed threads, and pressure relief valves.
“Most manufacturers are switching to these new systems,” said Vladimir M. Lemaine, regional sales manager at Johnstone Supply. “It’s becoming a requirement to obtain certification [related to the handling of A2Ls].”
HVAC students who complete the EPA 608 certification currently offered through the HVAC program at Franklin Cummings Tech will also be eligible to sit for the A2L certification exam; this credential shows a technician’s ability to safely handle flammable refrigerants such as R-32 and R-454B. Students will take the A2L exam during the second semester of the HVAC&R certificate program.
“Adding this credential to the HVAC&R Certificate curriculum underscores the college’s commitment to preparing students for eco-friendly and energy-efficient solutions in a changing HVAC landscape,” said HVAC&R Department Chair John Terasconi. “This certification shows that you care about your future and the future of the industry—and it looks great on a resume too.”
