Our take in 30 seconds
Best for: mixed climates with occasional hard freezesStrengths
- Heating efficiency (HSPF2 11) beats 92% of models
- Cooling efficiency up to SEER2 25.5, better than 95% of models
- Variable-speed compressor: quieter, steadier temperatures and better humidity control
- Uses newer, lower-impact R-454B refrigerant
Good to know
- Efficiency depends on the indoor unit: SEER2 ranges 19–25.5, 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 Payne 37MARAQ12AA3 at the three ENERGY STAR test temperatures (cooling capacity is 12,000 BTU/h for reference).
Retention at 17°F: 84% · at 5°F: 74%. Learn how to use these numbers in our cold-climate guide.
