Cold-climate heat pumps
Cold-climate heat pumps use variable-speed compressors and refrigerant systems engineered to maintain heating capacity at low outdoor temperatures.
Equipment we install
Selected for your home. Designed to work together.
What to look for
- Published capacity at low outdoor temperatures (manufacturer data)
- Variable-speed (inverter) compressor
- Listing on recognized cold-climate product lists [to be verified per model]
- Defrost performance
Designing for the coldest days
Every heat pump's capacity falls as temperature drops. We compare your home's heat loss at the local design temperature against the unit's published capacity and plan backup heat if needed.
Frequently asked questions
Do heat pumps work at -30°C?
Some models are rated to operate at very low temperatures, but capacity and efficiency are reduced. See our article on heat pumps at -30°C.
