About shared model numbers

Model numbers that appear under both brands in the certified data.

When the same model number is listed under two brands, we compare the certified figures. Each pair above says whether they match. The figures compared are the heating capacities at 5, 17, and 47°F, the COP at 5°F, SEER2, HSPF2, the cold-climate flag, and the list of indoor units.

Brand pairs that share at least 10 model numbers in the certified data. Each brand keeps its own AHRI reference numbers for the same pairing, so the reference numbers differ whether or not the figures do.
