Our take in 30 seconds
Best for: mixed climates with occasional hard freezesStrengths
- Cooling efficiency up to SEER2 20, better than 72% of models
- Variable-speed compressor: quieter, steadier temperatures and better humidity control
- Uses newer, lower-impact R-454B refrigerant
- Also sold under 8 other badges, so you can compare more quotes for the same unit
Good to know
- Efficiency depends on the indoor unit: SEER2 ranges 17–20, 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 Day & Night C5H3V60*K*AAA* at the three ENERGY STAR test temperatures (cooling capacity is 58,000 BTU/h for reference).
Retention at 17°F: 80% · at 5°F: 77%. Learn how to use these numbers in our cold-climate guide.
