AHRI Launches Interactive A2L Refrigerant Building Code Map of Canada

The Air-Conditioning, Heating, and Refrigeration Institute has released a new interactive map of Canada, which lists where the province and local building codes have been updated to allow equipment using A2L refrigerants. This Canadian map follows the successful 2024 launch of a U.S. version.

AHRI’s interactive maps are valuable tools for original equipment manufacturers, HVACR contractors, authorities having jurisdiction and others seeking information about applicable air conditioning and refrigeration, along with warehousing codes, legislation and standards referenced.

“The response to AHRI’s U.S. interactive map was overwhelmingly positive, so we were confident that providing this resource to our Canadian counterparts would be helpful to all stakeholders. AHRI’s interactive maps are the only comprehensive sources for information on building codes and legislation available, and will be updated as codes and laws change,” said Tom Deary, AHRI senior director of codes.

The Canadian refrigerant building code map was developed in consultation with the Heating, Refrigeration and Air Conditioning Institute of Canada. Access the Canadian map here and see the U.S. version here.
