When It Makes Sense
- Your AC needs replacing, and you'd like cheaper heat at the same time
- The house heats with electric baseboard, oil or propane
- Energy bills are higher than you want them to be
- There's no natural gas service on your street
What Moves the Price
- Size in tons, and whether the unit is cold-climate rated
- Variable-speed (inverter) or single-stage compressor
- A ducted system or a ductless mini-split
- Backup heat, either electric strips or a gas furnace (dual-fuel)
- Electrical panel capacity and wiring
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.
