Our take in 30 seconds
Best for: cold and very cold climatesStrengths
- Keeps 100% of its heat at 5°F, so backup heat rarely runs
- Cooling efficiency up to SEER2 22, better than 81% of models
- Variable-speed compressor: quieter, steadier temperatures and better humidity control
Good to know
- Uses R-410A, a refrigerant being phased down; future service may cost more

Heating capacity as it gets colder
A heat pump's output falls as outdoor temperature drops. This is the certified heat output of the Hisense AMW3-24U3SAA at the three ENERGY STAR test temperatures (cooling capacity is 24,000 BTU/h for reference).
Retention at 17°F: 62% · at 5°F: 100%. Learn how to use these numbers in our cold-climate guide.
