Our take in 30 seconds
Best for: cold and very cold climatesStrengths
- Keeps 83% of its heat at 5°F, so backup heat rarely runs
- Heating efficiency (HSPF2 10) beats 77% of models
- Cooling efficiency up to SEER2 26, better than 96% of models
- Variable-speed compressor: quieter, steadier temperatures and better humidity control
Good to know
- Efficiency depends on the indoor unit: SEER2 ranges 19.5–26, so ask which pairing you're quoted

Heating capacity as it gets colder
A heat pump's output falls as outdoor temperature drops. This is the certified heat output of the Gree GS24HP230V1PUO at the three ENERGY STAR test temperatures (cooling capacity is 22,000 BTU/h for reference).
Retention at 17°F: 83% · at 5°F: 83%. Learn how to use these numbers in our cold-climate guide.

Same equipment sold under other brands
These listings share the same certifying manufacturer (Gree Electric Appliances Inc. of Zhuhai) and identical certified capacities and efficiency ratings, so they are almost certainly the same hardware with a different badge. If you get quotes for any of them, you are comparing installation price and warranty, not equipment. How rebadging works.
