Strengths and watch-outs
Strengths
- Large ENERGY STAR-certified range of mini/multi-split and ducted split heat pumps, many listed as Cold Climate
- R-454B models listed on ENERGY STAR from October 2024, ahead of the 2025 A2L switch
Watch-outs

- ENERGY STAR still lists many Cooper&Hunter R-410A combinations; check that any quoted unit is a current A2L model
Which rebates Cooper & Hunter models fit
79 Cooper & Hunter outdoor models meet the cold-climate numbers NRCan publishes for its Eligible Products List (COP of at least 1.8 at −15°C at full output, 70% of rated capacity, a variable-speed compressor) on their ENERGY STAR ratings. That list decides Ontario's Home Renovation Savings rebate, Manitoba's, New Brunswick's, Yukon's and Newfoundland and Labrador's, and the federal National Heat Pump Rebate expected in early 2027. Check the exact pairing on NRCan's list ↗.
76 models meet ENERGY STAR Cold Climate, which earns Quebec's higher LogisVert rate. BC uses its own qualified list. Rebate rules by province:
