Heat pump vs Furnace in Yellowstone County, Montana
When a heat pump makes sense
A heat pump makes sense if you want cooling as well as heat and you plan to install a cold-climate model built to keep its heating power at low temperatures. Standard heat pumps lose heating power once it gets this cold, so the equipment choice matters more here than in milder places. At 16°F average winter nights, expect to run backup heat some of the time even with a cold-climate unit.
When a furnace makes sense
A furnace is the safer bet for most homes here, since natural gas costs at least 40% less to heat with than a heat pump at Montana prices, and you're paying for heat about 9 months of the year. It also holds its full output no matter how cold the night gets, which matters when winter lows average 16°F. If you don't need central air conditioning and want the lower running cost, this is the more straightforward choice.

Furnace wins in Yellowstone County.
Winter nights here average 16°F, and gas heat costs at least 40% less than a heat pump at Montana prices, so the furnace wins.
If your home has no gas line to it, a cold-climate heat pump will still heat it through a Montana winter, and it can cool the house in summer too.
