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

Heating capacity at 5°F as a percentage of rated heating capacity at 47°F. 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 Capacity retention at 5°F only, against their peers

Where each leader sits in its own peer groupCapacity retention 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, Carrier 37MPRAQ06AA3, beats 100% of 3,410 non-ducted, up to 1.5 tons models.
