As mentioned by HRAI President, Sandy MacLeod in his New Year’s message, theHRAI’s Emerging Technologies Committee is addressing the pending introduction of flammable refrigerants in Canada. He noted that, “besides having obvious implications for installer safety, the new refrigerants may require changes in training, regulations, codes and standards, life cycle management and public awareness.”

A new HRAI Task Team of industry experts has been formed to study the issue and has been reviewing the above implications and also assessing advocacy and research needs.

Meanwhile, a high level of industry activity verifies the increasing urgency for action in this area. New refrigerant directions affect safety, efficiency, carbon footprints and business opportunities. North American Technician Excellence (NATE) is developing an exam for flammable refrigerants, and the Air Conditioning Contractors of America (ACCA) has released a technical bulletin on Flammable A3 Refrigerants.

Most recently, several manufacturers have announced adoption of lower GWP (global warming potential) replacements, in partnership with refrigerant developers. A few of these are Carrier/Chemours, Tecumseh/Honeywell and Daikin/Mexichem.

Further guidance on safety measures and training opportunities is coming soon from HRAI and our partner organizations.
