Ranked by Heating capacity at 5°F only: up to 1.5 tons, by duct type

Maximum heating output at 5°F outdoor temperature. This board ranks by that one rating; it is not the overall cold-climate verdict, which is the cold-climate board. Inside one size and duct type the raw ratings are comparable, so these boards rank by the rating itself, more than one model per manufacturer when they earn it. Only manufacturers with a QMID (IRS Qualified Manufacturer ID) on file are ranked.

Ducted, up to 1.5 tons: ranked by Heating capacity at 5°F only

Ducted, up to 1.5 tons: ranked by Heating capacity at 5°F (Btu/h). Every model here is the same size and duct type, so the raw values are comparable. Ties go to the lower AHRI reference number; every number in a row is from that row’s certification.
