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 Oct 10, 2026

Showing Ducted, 2.5–3 tons (27,000–38,999 Btu/h cooling). What size is my system?

All-around best, ducted 2.5–3 tons

Balances heating (5°F output and efficiency, HSPF2) and cooling (SEER2, EER2), each rating against units their size.

1,896 of 2,185 models in this size class have all five ratings.
