The Heating, Refrigerating and Air-Conditioning Institute of Canada (HRAI) is meeting with its U.S. counterpart to discuss the divergence of U.S. and Canadian testing and rating standards for HVAC products. According to a newsletter issued by the American Air-Conditioning, Heating and Refrigeration Institute (AHRI), “the divergence raises questions about [the] future recognition of AHRI-certified products in Canada, and about the cost to manufacturers of additional testing in Canada. Both [institutes] agreed this is an unhealthy trend and needs to continue to be addressed with CSA and Natural Resources Canada (NRCan).”

The newsletter said that HRAI is continuing to monitor regulatory developments in the provinces. The Canadian organization has also agreed to add comments to an AHRI filing with the U.S.-Canada Regulatory Cooperation Council.
