Eight months of Midland winter wears a furnace down
Your furnace has to work from October through May here, eight months of the year. On winter nights that average 18°F, it runs long and cycles on and off again and again to hold the temperature. Every one of those starts puts wear on the igniter and the parts that get the burner going.
Most homes in Midland County heat with gas, and gas furnaces depend on power to run the blower and controls. Storms come through often enough here, 15 winter storms and 50 damaging wind events over the last ten years, and better than a third of Michigan households lost power for a day or more in 2024. When the power drops and comes back, a furnace that was already struggling can fail to relight or fail to restart at all.

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.
Michigan requires HVAC contractors to hold a state license.
Michigan tests contractors before handing out this license, and the Board of Mechanical Rules keeps the record of who holds one. The license belongs to the contractor, not to any single job, so it travels with them from house to house rather than getting issued fresh each time a homeowner calls.
For a furnace repair, that license is what stands behind the work. A gas furnace depends on a sound connection at every joint, and in Midland County most homes heat with gas, so that part of the job is exactly where a licensed contractor's training is supposed to show.

- Why won't my furnace turn on?
- Most of the time it's the thermostat, a tripped breaker, or the switch that looks like a light switch near the furnace itself. Check that switch first, since it gets bumped off by accident more than people expect. If the breaker keeps tripping or the furnace still won't respond, the igniter or the control board is a likely cause, and that's a job for a licensed contractor to check. With winter lows here averaging 18°F, it's worth getting looked at the same day rather than waiting.
- 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. That points to the igniter, the flame sensor, or a gas supply issue, none of which you can fix by adjusting the thermostat. It can also mean the furnace is in the middle of its startup cycle, which takes a minute or two before warm air comes through. If cold air keeps coming for longer than that, shut it down and have a contractor take a look.
- Why won't my furnace pilot light stay lit?
- This is almost always the thermocouple, the small sensor that sits in the pilot flame and tells the gas valve it's safe to stay open. When it wears out or sits slightly out of position, it reads the flame as out even when it isn't, and shuts the gas off. A draft blowing across the pilot can also cause the same thing. Either way, a licensed contractor can test and replace the thermocouple, and it's not something to keep relighting on your own.
