Heat pump vs Furnace in Sitka City and Borough, Alaska
When a heat pump makes sense
A heat pump makes sense if you want cooling as well as heat, or if you don't have natural gas run to your home. Look for a cold-climate model, since standard heat pumps lose heating power once temperatures drop toward the 31°F nights typical here. Even so, expect to pay well more to run it than a gas furnace at Alaska's prices, since you're heating close to year round.
When a furnace makes sense
A furnace is the right call if you have gas service to your home and want the lowest heating bill you can get. It costs at least 55% less to run than a heat pump here, and with heat needed most months of the year that adds up. The one thing it won't do is cool your home in summer.

Furnace wins in Sitka City and Borough.
