Heat pump vs Furnace in Carroll County, New Hampshire
When a heat pump makes sense
If you want cooling as well as heating from one system, a heat pump gives you both. Get a cold-climate model, since standard heat pumps lose heating power once temperatures drop toward 12°F, which is where nights here sit all winter. Expect to pay more to heat with electricity than a neighbor heating with gas.
When a furnace makes sense
If you already have a gas line and want the lower running cost, a furnace is the one to install. It heats through those 12°F nights without losing capacity, and gas costs at least 25% less than electric heat here. The tradeoff is that it only heats. You will still need a separate system if you want cooling in summer.
