All-around best heat pumps by size
Heat pumps that are good at everything, ranked against units their size: half the score is heating (how much heat they keep at 5°F, how efficient they are at 5°F and over a winter), half is cooling (seasonal and hot-day efficiency).
Covers heat pumps sold new today (R-454B and R-32 refrigerant). See older R-410A models · Updated
Showing Ductless, 2.5–3 tons (27,000–38,999 Btu/h cooling). What size is my system?
All-around best, ductless 2.5–3 tons
Balances heating (5°F output and efficiency, HSPF2) and cooling (SEER2, EER2), each rating against units their size.
1,084 of 1,141 models in this size class have all five ratings.
