Heat pump manufacturers and brands

The certified data lists 265 brands; 36 have at least 50 tier-1 certified units. 78 brands each share at least 10 model numbers with another brand.

Counts use tier-1 units, one representative per set of certified figures. A unit listed under several brands counts under each. Cold-climate units carry the designation on at least one certified pairing. Mini-split share uses each unit's main type: Central (ducted split and packaged systems) or Mini-split (including ducted mini-splits).

Equal counts share a rank; tied brands appear in alphabetical order. Group links show brands listed with at least 50 of the same model numbers; a dash means no published group. The A–Z counts below include all listed model numbers.

Every brand that appears on a certified air-source heat pump in the certified data, with the units listed under each. A unit sold under several brands is counted under each, so the counts add to more than the certified data holds.

The third column names the brands whose ranges overlap this one most, with the number of model numbers they share. Ten shared model numbers is the threshold for a pair to get a page, and a dash means no brand shares ten with this one. Which brands are the same?
