Ten months of heat puts real hours on a Sandpoint furnace
From September through June your furnace is what stands between your house and winter nights that average 22°F. That is ten months of the burner lighting, running, and shutting off, day after day. Each cycle puts wear on the igniter and the parts that control the flame, and eventually one of them fails.
The area sees frequent winter storms and damaging wind, and wind like that knocks out power. More than a third of homes here heat with electricity, and a furnace that runs on electricity for its blower and controls goes quiet the moment the power does, right when you need it most.

Idaho requires HVAC contractors to hold a state license.
The license is held by the contractor, not issued job by job. Idaho's HVAC Board tests and records the person or company before they can take furnace work, so the license follows them across every job they do, not this one alone.
For a furnace repair, that license is what stands behind the work. Gas repair is where a mistake turns dangerous, a loose fitting or a bad connection at the burner, and in Idaho the HVAC Board's license is the record that the contractor was tested to do that work correctly.

- Why won't my furnace turn on?
- Most often the thermostat isn't calling for heat the way it should, or power isn't reaching the furnace. Check that the thermostat is set below room temperature and has fresh batteries if it uses them. Next check the furnace switch, which looks like a light switch, near the unit, and the breaker at your panel. If those are fine, the igniter or a safety switch may have failed, and that calls for a licensed contractor to test.
- Why is my furnace blowing cold air?
- If air is moving but it is not warm, the furnace may be running the blower without the burners lighting. That points to an ignition problem, a dirty flame sensor, or a gas supply issue. It can also mean the thermostat fan setting is on rather than auto, which just circulates room air. With nights here averaging 22°F in winter, a furnace stuck like this needs attention fast, so have a licensed contractor check it the same day if you can.
- Why won't my furnace pilot light stay lit?
- This usually means the thermocouple has worn out and can no longer sense the flame to keep the gas valve open. A draft blowing across the pilot or a dirty pilot opening can also cause it. Relighting it yourself may hold for a day or two, but if it keeps going out, the part needs replacing. A licensed contractor can test the thermocouple and replace it, which is a straightforward repair.
