Top cold-climate picks: non-ducted, 2 tons
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: Non-ducted, 2 tons
655 of 903 models in this size class qualify. 198 keep less than 70% of their heat at 5°F and 50 have no 5°F heat output rating, so they cannot show it. 306 of the qualifiers are from manufacturers with a QMID on file (the ranked pool).
