Our take in 30 seconds
Best for: cold and very cold climatesStrengths
- Keeps 86% of its heat at 5°F, so backup heat rarely runs
- Heating efficiency (HSPF2 10.5) beats 85% of models
- Variable-speed compressor: quieter, steadier temperatures and better humidity control
- Uses newer, lower-impact R-454B refrigerant
Good to know
- No notable drawbacks in the certified data.

Heating capacity as it gets colder
A heat pump's output falls as outdoor temperature drops. This is the certified heat output of the Bryant 37MUHAQ24AA3 at the three ENERGY STAR test temperatures (cooling capacity is 24,000 BTU/h for reference).
Retention at 17°F: 83% · at 5°F: 86%. Learn how to use these numbers in our cold-climate guide.
