Our take in 30 seconds
Best for: mixed climates with occasional hard freezesStrengths
- Heating efficiency (HSPF2 11.5) beats 95% of models
- Cooling efficiency up to SEER2 22.5, better than 82% 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
- Efficiency depends on the indoor unit: SEER2 ranges 19.2–22.5, 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 Pioneer YN009GMFI22RPE at the three ENERGY STAR test temperatures (cooling capacity is 9,000 BTU/h for reference).
Retention at 17°F: 73% · at 5°F: 73%. Learn how to use these numbers in our cold-climate guide.
