Nine months of heat, nights near zero
Your furnace runs from September through May here, nine months out of the year. On nights that average 3°F, it cycles on and off for hours at a stretch to hold the house steady. Every start puts load on the igniter and the parts that get the burner lit, and that wear catches up over a winter this long.
Cass County also sees real storms, 68 winter storms and 172 damaging wind events over the last ten years. Wind like that can knock out power, and across North Dakota about 7% of households lost power for a full day or more in 2024. Furnaces need electricity to run the blower and controls even when the fuel is gas, so a power outage on a night this cold means no heat until it's back.

North Dakota requires HVAC contractors to hold a state license.
The license is issued to the contractor by the Secretary of State, not to each job. It means the state has that contractor on record, tested and accountable for the work carried out under that license. It does not mean an inspector checks the furnace once the repair is done.
That license requirement applies to work of $4,000 or more. Work under that amount does not need a licensed contractor. Whether this repair falls above or below that line depends on what the job turns out to need. The gas connection is still the dangerous part of the work, licensed or not.

- Why won't my furnace turn on?
- Start with the thermostat. Check that it's set to heat and the set temperature is above room temperature, and check the batteries if it uses them. If the thermostat looks right, check the breaker for the furnace and the switch that looks like a light switch near the unit, some homes have this off by accident. When none of that explains it, the problem is likely inside the furnace itself, a failed igniter or a safety switch that has shut the system down, and that calls for a contractor to open it up and test it.
- Why is my furnace blowing cold air?
- Most often this means the furnace is running the blower but the burners haven't lit. Furnaces blow air constantly to circulate heat, so a few seconds of cool air at startup before the burners catch is normal. If it's blowing cold the whole time it runs, the burners may not be lighting at all, or the furnace is overheating and shutting the burners off while the fan keeps going. A dirty filter can cause that overheating, so check the filter first. If the filter looks fine, this is a job for a contractor to diagnose.
- Why won't my furnace pilot light stay lit?
- This usually comes down to the thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out or sits out of position, the valve shuts the gas off soon after you let go of the button, even though the pilot lit fine a moment before. A draft blowing out the pilot is possible too, but if it happens over and over, the thermocouple is the more likely cause. Replacing it is a quick job for a contractor and not something to keep relighting on your own, especially through a Fargo winter when you cannot afford the furnace being down.
