Ranked by SEER2 only, for their size and type

Seasonal cooling efficiency (2023 DOE test procedure). 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 SEER2 only, against their peers

Where each leader sits in its own peer groupSEER2 of every model, one row per size and duct type · dots are the leaderboard below · R-410AEach 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 MCY-MAP0607HS-UL*, beats 100% of 32 non-ducted, 5 tons and up models.
