Ten months of heat, and nights near 18 degrees

Your furnace in Grangeville works from September through June. That is ten months of the year it has to be ready to fire, and on winter nights that average 18°F, it runs long and hard to keep up. Every cycle it lights, runs, and shuts off wears a little more on the igniter and the burner.

A lot of homes here heat with electricity, and when a storm knocks out power, the furnace stops with it. Idaho County sees its share of winter storms and damaging wind, and when the lights come back on, some furnaces do not restart on their own. If yours goes quiet after an outage, that is worth checking before you assume the worst.

Idaho requires HVAC contractors to hold a state license.

Idaho licenses HVAC contractors through the state HVAC Board. That license is issued to the contractor, not to each job, so the same license that covers an installation also covers a repair call like this one.

For a furnace repair, that license is the thing standing behind the work. The contractor doing the repair is the one the state has on record, whatever the job entails.

Why won't my furnace turn on?
The most common cause is the thermostat not sending power to the furnace, so check that it's set to heat and the batteries aren't dead. If the thermostat looks fine, the furnace may be getting no power at all. Check the breaker and the switch that looks like a light switch near the furnace, since either one being off will stop it cold. If power is reaching the furnace and it still won't start, a licensed contractor can find out why.
Why is my furnace blowing cold air?
If air is moving but it's not warm, the furnace may be running the blower without the burners lighting. That points to an ignition problem, a flame sensor that isn't reading the flame, or a safety switch shutting the burners down. It can also mean the furnace is in its startup delay, where the blower runs a few seconds before the burners fire, so cold air for a short time isn't always a problem. If the air stays cold the whole cycle, that's when it needs a look.
Why won't my furnace pilot light stay lit?
A pilot that won't stay lit usually means the thermocouple isn't sensing the flame, so the gas valve shuts back off to keep unburned gas from building up. It can also mean a draft is blowing the flame out, or the pilot orifice is dirty and the flame is too small to hold. A standing pilot doesn't need power to run, so this isn't an outage problem. With homes here needing heat from September through June, a pilot that won't hold is worth having a contractor look at soon rather than waiting.
