Showing the top 20 by SEER2. All 50 certified units in this group are filterable in the full database — we rank here rather than dump, because a table nobody can read is not a resource.

Capacity and efficiency are AHRI-certified values; $/MMBtu is computed by us from EIA energy prices — see methodology. Heat at 5°F is the number that decides whether a heat pump keeps up in real cold, and most listings omit it.
