Ranked by COP at 5°F only, for their size and type

Heating efficiency at 5°F outdoor temperature: units of heat delivered per unit of electricity. This board ranks by that one rating; it is not the overall cold-climate verdict, which is the cold-climate board. Small units rate higher than large ones and ductless units higher than ducted ones, so this board does not rank raw numbers across sizes. Each model is ranked by the share of comparable models (same size and duct type) it beats, one model per manufacturer. Only manufacturers with a QMID (IRS Qualified Manufacturer ID) on file are ranked.

Top 25 ranked by COP at 5°F only, against their peers

Where each leader sits in its own peer groupCOP at 5°F of every model, one row per size and duct type · dots are the leaderboard below · Low-GWP (R-454B, R-32)Each row is one size and duct type. Leaders are ranked by how far they stand out in their own row, not by the raw number. The #1, Mitsubishi Electric PUZ-AK42NL***, beats 100% of 564 non-ducted, 3.5–4.5 tons models.

Ranked by the share of comparable models (same size and duct type) each model beats on COP at 5°F, using each model’s best certification; equal shares go to the model further above its group’s typical value. The raw COP at 5°F is shown but not compared across sizes.
