Heat pump vs Furnace in Cowlitz County, Washington
When a heat pump makes sense
If your home doesn't have a gas line, a heat pump is the straightforward choice, since it runs on electricity alone and handles both heating and cooling. Winter nights here average 33°F, which is cold but not extreme, so a cold-climate model will hold its heating power through the season instead of struggling like a standard one might. With heat needed about 10 months a year, you'll want a unit built for that stretch of use.
When a furnace makes sense
A furnace fits a home that already has a gas line run to it and where gas heat costs at least 5% less than a heat pump at Washington prices. It only heats, so you'd still need separate cooling if summers matter to you. Only 6% of homes here heat with gas, so this makes sense mainly if you're already set up for it.
