Nine months of heat puts a lot of wear on your furnace
From September through May, your furnace is what keeps the house warm through nights that average 13 degrees. That is nine months of cycling on and off, and every start puts load on the igniter and the blower motor. Most homes here heat with gas, so when the burner won't light, the house cools off fast.
Outagamie County has seen 22 winter storms and 79 damaging wind events over the past ten years. Across Wisconsin, 18 percent of households lost power for at least 24 hours in 2024. When power drops during a cold stretch, a furnace with a weak igniter or an aging blower motor often will not start again on its own once the power comes back.

A new furnace would cut about $110 a year off heating for a typical Outagamie 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.
Wisconsin requires contractors to register with the state.
That registration puts the business on file with the Department of Safety and Professional Services. It does not mean anyone tested the contractor's gas or furnace work, and there is no state exam behind the name. Wisconsin also does not let counties or cities layer on their own HVAC license, so what you get in Outagamie County is the same statewide record and nothing more local to check against.
For a furnace repair, the part that matters most is the gas connection, since a bad one is what makes the job dangerous. That check does not come from the state registration, and the facts here name no local inspection standing behind it either. With 70.7% of homes in Outagamie County heating with gas, that connection is the thing this repair comes down to, registration or not.

- Why won't my furnace turn on?
- The most common reason is the thermostat isn't calling for heat the way it should, but a tripped breaker or a switched-off power source at the furnace itself causes this just as often. Check the thermostat has power and is set above room temperature first. If that's fine, look for a service switch near the furnace that may have been bumped off, or a breaker that tripped. When power and thermostat both check out, the problem is likely inside the furnace, and a contractor will need to find out which part is stopping it from starting.
- Why is my furnace blowing cold air?
- Air that stays cold once the blower kicks on usually means the burners aren't lighting even though the fan is running. This can come from a bad igniter, a flame sensor that isn't reading the flame, or a gas supply problem. A dirty filter can also cause short cycling that feels like cold air blowing. With winter lows here averaging 13°F, a furnace that runs but never lights the burners is worth checking soon rather than waiting it out.
- Why won't my furnace pilot light stay lit?
- A pilot light that won't stay lit is almost always a thermocouple problem. The thermocouple sits in the pilot flame and tells the gas valve it's safe to keep sending gas. Once it wears out or sits out of position, it reads the flame as out even when it isn't, and the valve shuts the gas off. A draft blowing across the pilot can also do this, so check that nothing is disturbing the flame before ruling out the thermocouple.
