Our take in 30 seconds
Best for: cold and very cold climatesStrengths
- Keeps 100% of its heat at 5°F, so backup heat rarely runs
- Cooling efficiency up to SEER2 23.8, better than 91% of models
- Variable-speed compressor: quieter, steadier temperatures and better humidity control
- Uses newer, lower-impact R-32 refrigerant
Good to know
- Efficiency depends on the indoor unit: SEER2 ranges 17–23.8, 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 Samsung AC018DXSCCG at the three ENERGY STAR test temperatures (cooling capacity is 18,000 BTU/h for reference).
Retention at 17°F: 82% · at 5°F: 100%. Learn how to use these numbers in our cold-climate guide.
