Top cold-climate picks by size

Heat pumps that keep most of their heat when it is 5°F outside, ranked on three ratings at once against units their size: how much heat they keep, how efficient they are at 5°F, and how efficient they are over a whole winter (HSPF2).

Covers heat pumps sold new today (R-454B and R-32 refrigerant). See older R-410A models · Updated

Top cold-climate picks, ductless 2.5–3 tons

Only units that keep at least 70% of their heat at 5°F, ranked on heat kept, efficiency at 5°F and seasonal efficiency (HSPF2), against units their size.

873 of 1,140 models in this size class qualify. 210 keep less than 70% of their heat at 5°F and 55 have no 5°F heat output rating, so they cannot show it.
