343 heat pump manufacturers, compared like for like
Small units rate higher than large ones and ductless higher than ducted, so a manufacturer’s raw median mostly reflects which sizes it makes. Instead each model is compared with models of the same size and duct type, and a manufacturer’s score is the average share of those comparable models its models beat: 50 is typical, whatever the mix. Brands are grouped under the company that owns them (Bryant and Payne under Carrier, Amana and Goodman under Daikin). Only manufacturers with a QMID on file are ranked, once at least 10 of their models are scored on a rating.

Catalog size against efficiency
One dot per manufacturer: how many outdoor models it certifies, and its efficiency index (the average share of same-size, same-type models its models beat).
- QMID on file (ranked)
- No QMID (not ranked)
- 50 = typical for its sizes
Hover or focus a dot for its models' spread. Manufacturers with fewer indexed models are left out: their index would rest on a handful of listings.

Download CSV of every manufacturerEvery manufacturer, ranked or not, with scores, ranks, medians and standards.
Ranked on: index 29 · COP@5°F 29 · Cap. 5/47 29 · HSPF2 29 · SEER2 29 · EER2 29 · Btu/h @5°F 29 manufacturers. A manufacturer without a rank has fewer than 10 models scored on that rating.
How concentrated is the catalog?
Measured on certified models, not on sales. A manufacturer can certify many models and sell few, or the reverse.
- Cumulative share of models
- Every manufacturer equal
Catalog sizes are very unequal (a long tail of small manufacturers), yet the largest holds only 6.6%, so the HHI stays low.
Source: AHRI Directory · as of
187
Unconcentrated on the 2023 U.S. merger-guideline scale (0–1,000). The same score as 53 manufacturers with equal catalogs.

Top-four share (CR4) is the combined share of the four largest catalogs: 20.1% of all certified outdoor models.
HHI (Herfindahl–Hirschman Index) adds up the squared percentage shares of every manufacturer. One company with everything scores 10,000; many small, equal players score near zero. U.S. antitrust guidelines (2023) call a market above 1,800 highly concentrated. At 187, the certified catalog is unconcentrated.
Not ranked: no QMID on file (313)
These manufacturers have no IRS Qualified Manufacturer ID (QMID) on file, so they are not ranked. Their models are still in every count, in Explore and on their own pages.
