Nine months of heat, nights near zero
Your furnace runs from September through May here. On the coldest nights it holds the house against an average low of 0°F, cycling on and off for hours at a stretch. Every one of those cycles puts a load on the igniter and the blower motor, and that adds up fast over a nine month season.
Beltrami County has seen 67 winter storms and 99 damaging wind events over the past ten years. Storms like that knock out power, and across Minnesota 13% of households lost power for 24 hours or more in 2024. When the power drops and comes back, most furnaces restart on their own, but if the ignition system was already worn down, that's often the moment it fails to relight.

Minnesota has no state license for HVAC contractors.
There is no state license and no state registration for HVAC contractors in Minnesota, including here in Beltrami County. That is true for furnace repair the same as any other HVAC job. No state board tested this contractor or put their name on file before they took the job.
Gas furnace repair is the part of this job where a mistake matters most, since a bad connection is what makes it dangerous. In Minnesota, that work is not reviewed by any state board. Nothing at the state level stands between a homeowner and the contractor doing this repair.

- Why won't my furnace turn on?
- Most often the thermostat isn't calling for heat, a safety switch has tripped, or power to the unit is interrupted. Check that the thermostat is set above room temperature and that the furnace switch and breaker are both on. A dirty filter can also block airflow enough to trip a limit switch and shut the furnace down. If those check out and it still won't start, a contractor will need to test the ignition system and safety controls to find the fault.
- Why is my furnace blowing cold air?
- If air is moving but it's not warm, the furnace may be running its fan without the burners lighting. A dirty flame sensor is a common cause of that, since it can't confirm the flame and shuts the burners off as a safety measure. It can also mean the igniter isn't lighting the gas at all. Either way the fan keeps blowing while nothing heats it, and a contractor will need to check the ignition system to tell which part has failed.
- 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 actually present. When it wears out or sits out of position, it reads no flame even when the pilot is lit and shuts the gas off. A draft blowing across the pilot can cause the same problem. Since homes here need working heat from September through May, it's worth having a contractor check the thermocouple and pilot assembly rather than relighting it over and over.
