Eight months of heat puts real wear on a furnace
From October through May your furnace is the thing standing between you and a 21°F night. That is eight months of the year it has to work, and on the coldest nights it cycles on and off again and again to hold the temperature. Every one of those cycles asks the igniter to light the burner one more time, and igniters wear out from the counting, not the cold.
Most homes in Berrien County heat with gas, so when the igniter fails or the flame sensor gets dirty enough to shut the burner down, the furnace stops making heat and nothing else in the house can take its place. Power matters too. Berrien County has logged 12 winter storms and 81 damaging wind events over the past ten years, and statewide, a third of households lost power for a day or more in 2024. A furnace with no power will not run no matter what shape its parts are in.

A new furnace would cut about $140 a year off heating for a typical Berrien 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.
Michigan requires HVAC contractors to hold a state license.
The Board of Mechanical Rules tests contractors before granting this license, and it keeps a record of who holds one. That license belongs to the contractor, not to any single job, so nothing gets reissued or checked off each time someone comes out to repair a furnace. It stands behind the person doing the work, in every county, on every furnace they touch.
For a furnace repair, the part that matters most is the gas connection, since a bad one is what makes the job dangerous rather than just ineffective. In Berrien County, where 64.4% of homes heat with gas, that connection is exactly what this license holds someone accountable for. The license covers the contractor's standing to do the work at all, not a sign-off on this particular repair.

- Why won't my furnace turn on?
- Start with the thermostat. Check that it's set to heat and the temperature is above room temperature, and put in fresh batteries if it uses them. If that's not it, check the breaker for the furnace and the switch that looks like a light switch near the unit, sometimes mounted on the side or on a nearby wall. Furnaces also won't fire if the filter is badly clogged or if the drain line from a high-efficiency furnace is blocked, since both trip safety switches meant to shut the unit down. If none of that gets it running, a contractor will need to check the igniter and the control board.
- Why is my furnace blowing cold air?
- Most often this means the blower is running but the burners haven't lit. A dirty flame sensor is a common cause. It's a small metal rod near the burners that tells the furnace a flame is present, and once it's coated with residue the furnace shuts the gas off within seconds of starting, so you feel air but no heat. A clogged filter can cause the same thing by starving the burners of airflow. If your thermostat fan setting is on rather than auto, the blower runs constantly and will feel cool between heating cycles, which is normal. If the air stays cold with the fan on auto, the furnace needs a contractor to look at the ignition system.
- Why won't my furnace pilot light stay lit?
- This usually points to the thermocouple, the small sensor that sits in the pilot flame and tells the gas valve it's safe to keep the gas flowing. When it wears out or sits out of position, the flame lights, burns for a few seconds, then goes out as the gas valve closes. A draft blowing across the pilot or a dirty pilot orifice can cause the same pattern. A contractor can test the thermocouple and replace it if that's the cause.
