Nine months of heat, and nights near zero
Your furnace runs September through May in Devils Lake. That is nine months of the year it has to work, and on winter nights that average 0°F, it runs long and hard to keep up. The burner cycles on and off for hours at a stretch, and every cycle puts wear on the igniter and the flame sensor.
This county has seen 48 winter storms and 74 damaging wind events over the past ten years. Storms like that knock out power, and across North Dakota, 7% of households went at least 24 hours without it in 2024. A furnace that loses power mid-cycle has to restart cold, right when the house needs it most.

North Dakota requires HVAC contractors to hold a state license.
The state license is issued to the contractor, not to the individual job. It covers the business itself, so the same license applies whether the work is a furnace repair, an installation, or a service call.
North Dakota sets one exception to that rule. Work under $4,000 does not need a licensed contractor. A furnace repair can fall on either side of that line depending on the job. Where gas lines are involved, a bad connection is the dangerous part of the work, and that risk does not change based on the price of the repair.

- Why won't my furnace turn on?
- The most common cause is a control problem, not the furnace itself. Check the thermostat first, since a dead battery or a setting bumped too low will stop the call for heat before it ever reaches the furnace. After that, check the breaker and the furnace switch, which looks like a light switch near the unit and gets turned off by accident more often than people expect. If those are fine, the furnace may be stopping itself on purpose because a safety switch has tripped, and a contractor will need to find out why.
- Why is my furnace blowing cold air?
- Most of the time this means the blower is running but the burners never lit. Furnaces run the fan for a short delay before heat kicks in, so a few seconds of cool air is normal. If it keeps blowing air that never warms up, the igniter or the flame sensor is likely failing to start or hold a flame. A dirty filter can also cause this by making the furnace overheat and shut the burners off while the fan keeps running, so check the filter before calling anyone.
- Why won't my furnace pilot light stay lit?
- This usually points to the thermocouple, the small sensor that tells the gas valve a flame is present. When it wears out or sits out of position, it reads no flame even when one is lit, and the gas valve shuts off to protect the house. A draft blowing across the pilot or a dirty pilot orifice can cause the same thing. This is a gas part, so it needs a licensed contractor to test and replace rather than something to keep relighting on your own.
