Compare ENERGY STAR heat pumps
Search every ENERGY STAR-certified heat pump system and compare up to four side by side: efficiency, heating capacity in cold weather, compressor type and refrigerant — exactly as certified.
Find certified heat pumps
How to use it
- Start with the size you need. If you do not know it, estimate it with the AC Tonnage Calculator or the Room-by-Room Load Calculator.
- Search by size and brand, or type the start of a model number from a quote or a rating plate.
- Tick up to four systems to compare them side by side. The page address then holds your comparison, so you can bookmark it or send it to your contractor.
- In a cold climate, follow “Check its balance point” to open the Heat Pump Balance Point Calculator with that system’s listed capacities, and see how much backup heat it would need at your design temperature.
What the ratings mean
- SEER2 is seasonal cooling efficiency and EER2 is cooling efficiency at one hot condition. Higher is better for both.
- HSPF2 is seasonal heating efficiency. Higher is better.
- COP at 5 °F is the heat delivered per unit of electricity when it is 5 °F outdoors.
- “Cold climate” means the system meets ENERGY STAR’s cold-climate criteria.
- The AHRI reference number identifies the certified combination in the AHRI Directory.
Frequently asked questions
Where does this data come from?
From the ENERGY STAR Certified Heat Pumps dataset published by the U.S. Environmental Protection Agency. It lists every certified system with the ratings its manufacturer reported. We download it weekly and show the date of the copy we are using.
Why is a heat pump I was quoted missing?
Only ENERGY STAR-certified systems are in the dataset. A system can be a legitimate, AHRI-rated product without being ENERGY STAR certified. Also try fewer characters of the model number: listed model numbers often contain * wildcards that stand for options such as voltage or colour.
What do the 47 °F, 17 °F and 5 °F capacities mean?
They are the heating capacity measured at those outdoor temperatures. The 5 °F figure shows how much heat the system still delivers in cold weather. In this dataset the 47 °F and 5 °F values come from different tests, so the ratio between them is only indicative — for sizing, use the maximum-capacity tables in the manufacturer’s extended performance data, as the NEEP sizing guide recommends.
Does a listing mean the indoor and outdoor units are compatible?
A listing shows a combination that was certified together. Other pairings are not covered by this data, so check them with the manufacturer or the AHRI Directory before buying.
Is this a recommendation?
No. We list certified systems exactly as reported and let you sort and compare them. Sizing comes first: estimate your heating and cooling load, then compare systems of the right capacity.
