Nine months of heat, nights near zero
Grand Rapids asks a furnace to run from September through May. That is nine months of cycling on and off, night after night, with winter lows that average 1°F from December through February. At that temperature the burner is firing almost constantly to keep up, and every start puts wear on the igniter and the flame sensor. Those are usually the first parts to fail, and when they do, the furnace either won't light or shuts itself off partway through the cycle.
This area also sees real weather. Ten years of records show 59 winter storms and 108 damaging wind events, and across Minnesota 13% of households lost power for 24 hours or more in 2024. A furnace that loses power mid-cycle needs to relight on its own, and an igniter that was already worn may not manage it. If your furnace has gone quiet during a cold snap or after the lights flickered, that is usually why.

A new furnace would cut about $140 a year off heating for a typical Itasca County home.

Repair makes sense when one part has failed and the heat exchanger is sound.
Replacement makes sense when the heat exchanger is cracked or the furnace keeps needing parts.
Minnesota has no state license for HVAC contractors.
Minnesota keeps no list of HVAC contractors and tests none of them. There is no state board checking who worked on a furnace before this one, so nothing here comes from a license because there is nothing to check.
For a gas furnace repair, the part that matters is the gas connection itself, since a bad one is what makes the job dangerous. Minnesota does not put a state inspector on that check for home HVAC work. In Itasca County, gas heat runs about 40.6% of homes, so this kind of repair is common work here, done without a state license behind it either way.

- Why won't my furnace turn on?
- Most often the thermostat isn't calling for heat the way you think it is, or power isn't reaching the furnace. Check that the thermostat is set below room temperature and has fresh batteries if it uses them. Next check the furnace switch, which looks like a light switch near the unit, and the breaker it runs on. If those are fine, the igniter or the flame sensor may have failed, and that's a repair for a contractor to diagnose.
- Why is my furnace blowing cold air?
- Air blows before the burners light, so a few seconds of cool air at startup is normal. If it stays cold the whole cycle, the burners likely aren't igniting even though the blower is running. That points to the igniter, the flame sensor, or the gas valve, and none of those are safe to test yourself. With nights here averaging 1°F in the dead of winter, a furnace stuck blowing cold air needs a same-day look.
- Why won't my furnace pilot light stay lit?
- A pilot that won't stay lit almost always means the thermocouple has worn out. That's the small sensor the pilot flame heats to prove it's burning. When it fails, it tells the gas valve no flame is present even when there is one, and the valve shuts the gas off. It's a straightforward part for a contractor to replace.
