Heat pump vs Furnace in Fairbanks North Star Borough, Alaska
When a heat pump makes sense
If you want cooling in summer as well as heat, a heat pump is the only one of the two that does both. Standard models lose heating power in cold weather, and Fairbanks nights average -10°F from December through February, so that would mean a cold-climate model built for it. Even then, you would be running on electricity through about 11 months of heating a year, and gas runs at least 55% cheaper here.
When a furnace makes sense
If your home has a natural gas line, a furnace is worth choosing on cost alone. It costs at least 55% less to heat with here than a heat pump, and its output does not drop when the temperature does, which matters on nights that average -10°F from December through February. With heat needed about 11 months of the year, that gap adds up.

Furnace wins in Fairbanks North Star Borough.
At -10°F on a December night you want a furnace working, not a heat pump, and gas here costs at least 55% less to run.
If your home has no access to natural gas, a cold-climate heat pump will still heat it through a Fairbanks winter and cool it in summer besides.
