Common Questions

Do heat pumps work in cold weather?

Yes. Cold-climate heat pumps keep making heat well below 0°F. They lose efficiency as it gets colder, so many homes in cold regions keep backup heat.

How long does a heat pump last?

Usually 12 to 15 years. A heat pump runs year-round, so it needs maintenance twice a year rather than once.
