CertifiedSpecs

Heat pump directory

Every ducted heat pump on the EPA's ENERGY STAR certified list, grouped by the brand on the outdoor unit: 5,521 outdoor models from 194 brands, covering 266,456 certified pairings of outdoor unit with indoor coil.

The outdoor model number alone does not determine the efficiency. It is the pairing of outdoor unit with a specific indoor coil and air handler that carries an AHRI certificate, and 44.3% of these outdoor models appear at more than one HSPF2 rating depending on which coil is fitted. That is what this directory is for: finding out how much the choice of coil moves the number on your quote.

One model number, several brand names

Before you compare brands, it is worth knowing that many outdoor model numbers are certified under more than one brand name. Of the 3,026 distinct outdoor model numbers in this list, 846 (28%) appear under more than one brand name, and the largest case carries 17 brands on a single model number. Those shared model numbers account for 75% of the certified pairings in the list.

Each brand files its own AHRI certificate, so no certificate number is shared. The model number is what gives it away. A shared model number is strong evidence of shared equipment, not proof that manufacture, warranty or support are identical. What that means when you are comparing quotes is its own guide.

Models worth a closer look

These 16 have their own page because the indoor coil moves their running cost more than almost anywhere else in the catalogue, so pinning down the exact pairing is worth the trouble. The selection comes from the data alone — how they were chosen is written down, and no search volume or popularity figure is involved, because none is available to us.

Annual difference is between the lowest and highest HSPF2 this outdoor unit is certified at, for 40 million BTU of delivered heat at 17.11¢/kWh. It is a reference scenario for ranking, not a bill.

Brands

39 brands have a page of their own: those with at least 20 outdoor models and 1,000 certified pairings, which is enough data to describe a range rather than repeat a single certificate, plus any brand with a model page above. Together they cover most of the list. The remaining 155 are listed below with their figures, and all of them are searchable in the calculator.
