Every certified model by size and rating11,475 outdoor models with a known size and duct type · R-410AAt 5°F, ducted and non-ducted models are close (median COP 1.95 and 1.89). On cooling they are not: median SEER2 20.5 non-ducted, 15.8 ducted. That gap is why every ranking compares a model only with models of its own size and duct type.

Dots: 1,200 of 11,475 models, a fixed sample drawn from every size and duct type in proportion; the grey shapes count all of them, half a ton at a time. A model is plotted through its representative certification; the few beyond the axis range are counted but not drawn.

Key facts

How many models meet each standard

A model counts when at least one of its certified indoor pairings meets every criterion on its own.
From duct type to cold-climate tier9,640 outdoor models; each band is the models that share a path, each model in exactly one band48.4% of models meet CEE Tier 1 (2025) and 45.5% the stricter 2026 level, but only 1.4% (137) reach the cold-climate tier: full capacity and a COP of 2.1 at 5°F. 2 of those miss Tier 1 itself, on a cooling rating.
Duct typeCEE Tier 1CEE Advanced / DOE CCHP

Cold-climate tier = CEE Advanced, which uses the same rating criteria as the DOE Cold Climate Heat Pump Challenge (HSPF2 8.5, COP 2.1 at 5°F, 100% capacity at 5°F). It has no SEER2/EER2 path, so a model can reach it without meeting Tier 1.

Cold-weather leaders

Top cold-climate picks first: 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. One model per manufacturer, among manufacturers with a QMID on file. The two single-rating boards beside it are ranked by that one rating only.

How efficient is a typical heat pump at 5°F?

Half of the 7,758 models with a 5°F rating reach a COP of 1.93 or more, and the middle half sit between 1.80 and 2.10. CEE Tier 1 asks for at least 1.75; the cold-climate tier for 2.1.

What happens to capacity as it gets colder

Among the models listed by NEEP, a typical ducted unit still delivers 62% of its 47°F capacity at 5°F, and a typical non-ducted one 62%; efficiency falls from a COP near 3.2 to 2.06 over the same range.
