Top cold-climate picks: ducted systems, by size

Qualifies when its capacity retention at 5°F (capacity at 5°F as a share of capacity at 47°F) is at least 70% and Capacity retention at 5°F, COP at 5°F, HSPF2 are all rated. Score = the equal-weight mean of its peer percentiles on Capacity retention at 5°F, COP at 5°F, HSPF2 (share of the other models in its peer group it beats, 0–100), all from one certified pairing: in each duct type a model is sold in, its qualifying pairing of that type with the best score; equal scores (one decimal) go to the higher heating capacity at 5°F. COP at 5°F alone is not used: it is measured at whatever heat output the unit delivers at 5°F, so a unit with little output there can still post a high COP. The single-rating boards remain, each labelled as ranked by that one rating. Only manufacturers with a QMID (IRS Qualified Manufacturer ID) on file are ranked.

Top cold-climate picks: Ducted, up to 1.5 tons

1,420 of 1,824 models in this size class qualify. 361 keep less than 70% of their heat at 5°F and 42 have no 5°F heat output rating, so they cannot show it. 412 of the qualifiers are from manufacturers with a QMID on file (the ranked pool).

Ducted, up to 1.5 tons: qualifiers ranked by cold-climate score (mean of the three peer percentiles); equal scores go to the higher heat output at 5°F. Every number in a row is from the pairing the score is computed on: in each duct type, the model’s best-scoring pairing that keeps at least 70% of its heat.
