Our take in 30 seconds
Best for: cold and very cold climatesStrengths
- Keeps 82% of its heat at 5°F, so backup heat rarely runs
- Heating efficiency (HSPF2 10.5) beats 85% of models
- Cooling efficiency up to SEER2 23, better than 87% of models
- Variable-speed compressor: quieter, steadier temperatures and better humidity control
Good to know
- Efficiency depends on the indoor unit: SEER2 ranges 18–23, 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 Carrier 27VNA324A*030* at the three ENERGY STAR test temperatures (cooling capacity is 23,800 BTU/h for reference).
Retention at 17°F: 94% · at 5°F: 82%. Learn how to use these numbers in our cold-climate guide.
