Ranked by EER2 only, for their size and type

Cooling efficiency at a 95°F design day. 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 EER2 only, against their peers

Where each leader sits in its own peer groupEER2 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 MUZ-FX06NLHZ***, beats 100% of 3,563 non-ducted, up to 1.5 tons models.
