Ten months of heat a year, and nights that average 21°F
Colville needs a furnace September through June, ten months of the year. That is most months spent leaning on it, with winter nights averaging 21°F. A new furnace here has to hold up to a long, hard season, not just a cold snap.
Power matters too. Nearly a quarter of Washington households went at least a full day without power in 2024, and this area has logged 319 winter storms and 31 damaging wind events over the past ten years. With 43.2 percent of homes here heating with electricity, a furnace that depends on the grid needs a plan for when the lines go down. Any new gas furnace installed today also has to meet the federal minimum of 80 percent AFUE, so at least that much of every therm it burns goes into heating the house.

Washington requires contractors to register with the state.
Registration means the contractor's business is on file with the Department of Labor and Industries, with proof of bond and insurance behind it. It does not mean anyone tested their gas or furnace work. There is no trade exam here, so the state's record stops at who they are and whether they are covered, not whether they know how to size a flue or set a gas valve correctly.
For a furnace install, the check on the actual work happens at the local building office. Replacing a furnace in most Stevens County cities and towns needs a permit, and the finished job gets inspected before anyone can call it done. That inspection is what catches a bad gas connection or a venting mistake, not the state registration.

- What size furnace does my house need?
- The right size comes from a load calculation, not a rule of thumb. A contractor measures your square footage, your windows, your insulation, and your ceiling height, then works out how much heat your house loses on a cold night. With winter lows here averaging 21°F, that number matters more than it would somewhere milder. A furnace that's too big will short cycle and wear out faster. One that's too small will run constantly and still leave rooms cold.
- How do I know it's time to replace my furnace?
- Watch for a furnace that cycles more often than it used to, rooms that won't hold a temperature, or a heating bill that keeps climbing without a reason. Age matters too. Homes here need heat ten months a year, so a furnace in this area works harder over its life than one in most places. If yours is cutting off, restarting on its own, or needs a repair call more than once a season, replacing it is usually the sounder move.
- Is a high-efficiency furnace worth it?
- Every new non-weatherized gas furnace sold today already has to hit at least 80 percent AFUE, so the real question is whether you want to go higher than that baseline. With heat needed ten months out of the year here, a furnace that runs more efficiently is doing that work almost constantly, not just for a few cold weeks. A contractor can walk through the options for your house and price out what each one would mean for your specific setup.
