Nine months of heat, five below on a bad night
Lisbon needs furnace heat from September through May. That is nine months of the burner cycling on and off, and on the nights it works hardest, the average low is 5°F. At that temperature the furnace runs long stretches just to hold the house steady, and every start puts load on the igniter and the blower motor.
Almost half the homes in the area heat with electricity, and this part of North Dakota sees real weather that puts power at risk. Over the past ten years the area has logged 54 winter storms and 46 damaging wind events. Statewide, 7% of households lost power for at least 24 hours in 2024. When the power drops on a cold night, an electric furnace stops producing heat, and most units start back up on their own once power is restored. If yours does not, or if it was already struggling before the outage, that is worth a look.

North Dakota requires HVAC contractors to hold a state license.
North Dakota licenses HVAC contractors through the Secretary of State. The state tests the contractor and keeps that record on file. The license belongs to the business, not to any single job, so it is the contractor who is licensed, not this particular repair.
For a furnace repair, that license is what stands behind the work in North Dakota. The state sets one exception. Work under $4,000 does not need a licensed contractor. A furnace repair can fall on either side of that line.

- Why won't my furnace turn on?
- Start with the thermostat. If the screen is blank or the setting won't hold, the batteries may be dead, and a furnace won't get the call for heat without that signal. Check the breaker next, since a tripped one will shut the whole system down. If power and thermostat both check out, the igniter or the flame sensor may have failed, and a contractor will need to test those directly.
- Why is my furnace blowing cold air?
- The furnace is likely running the blower without lighting the burners. That points to an ignition problem, a bad flame sensor, or a gas supply issue that's shutting it down before it can heat the air. A dirty filter can also choke off airflow enough to trip the limit switch, which cuts heat but leaves the fan running. Check the filter first, then call for a diagnosis if that's not it.
- Why won't my furnace pilot light stay lit?
- A pilot that won't stay lit usually means the thermocouple has worn out. That's the small sensor that tells the gas valve the pilot is burning, and once it fails, the valve shuts the gas off as a safety measure. A draft blowing across the pilot or a dirty pilot orifice can also cause this. With winter lows here averaging 5°F, this isn't something to leave for long, since a furnace stuck in safety shutoff won't run at all.
