Cold-Climate Heat Pumps: What Upper Valley Homeowners Should Know
Can a heat pump really heat a Vermont or New Hampshire house in January? Here's how they work and what to ask an installer.
Key takeaways
- Cold-climate models are designed to keep heating well below zero.
- Many homes keep a backup heat source for the coldest nights.
- Proper sizing and placement matter as much as the brand.
- Check Efficiency Vermont or NHSaves for current rebates before you buy.
Do they work here?
Modern cold-climate heat pumps can provide heat at outdoor temperatures well below 0°F, though their output and efficiency drop as it gets colder. The Northeast Energy Efficiency Partnerships (NEEP) keeps a list of models that meet cold-climate performance standards.
Whole-house or partial
Some households use one or two ductless units for the main living areas and keep their boiler or furnace for backup. Others heat the whole house with ducted or multi-zone systems. Older homes that have been air sealed and insulated are usually easier to heat.
Questions to ask an installer
Bring these questions to every estimate so you can compare quotes fairly:
- Will you do a room-by-room heat-load calculation?
- How much heat does this model provide at 5°F and -5°F?
- Where will the outdoor unit go so snow, ice and roof runoff stay clear?
- Does my electrical panel need upgrades?
- How should my backup heat and the heat pump work together?
Rebates and programs
Efficiency Vermont, NHSaves and some local utilities offer heat pump incentives, and many require approved installers. Programs change, so confirm current terms before you sign a contract.
