Eight months of heat wears a furnace down in Anderson
Your furnace works from October through May here. On winter nights that average 22°F, it cycles on and off for hours to keep the house warm, and every cycle puts a little more wear on the igniter and the burner.
Madison County has seen 13 winter storms and 68 damaging wind events over the past ten years, and across Indiana, 17% of households lost power for at least 24 hours in 2024. A furnace needs electricity to run even if it burns gas, so when the power goes out in a storm, the heat goes with it. Most furnaces start again on their own once power returns, but one that was already struggling may not.

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.
In Indiana, HVAC licensing for homes is left to the counties and cities.
Whether a contractor needs a license to repair a furnace here depends on the city or town the house is in, since Indiana leaves that rule to the counties and cities. Some places keep their own licensing office and some do not, so the protection a homeowner has is a matter of address, not a record that holds true everywhere in Madison County.
For a furnace repair, the gas connection is the part that matters most, since that is the dangerous part of the job. Whether anyone checks it depends on the same local rule, and in a county where 66.4% of homes heat with gas, that connection is part of most furnace repairs done here.

- Why won't my furnace turn on?
- Start with the thermostat. Make sure it is set to heat and set a few degrees above room temperature, and check that the batteries aren't dead. If the thermostat looks right, check the breaker and the furnace switch, which looks like a light switch near the unit. Many furnaces also stop for a clogged filter or a safety switch tripped by a full condensate line, and a contractor can trace it from there.
- Why is my furnace blowing cold air?
- Most often the furnace is running the blower but the burners haven't lit. That points to an igniter that isn't glowing, a flame sensor coated in residue, or a gas valve that isn't opening. It can also just be air still in the ducts at the start of a cycle, cooling before the burners catch. If cold air keeps blowing past the first minute or two, have it looked at, since a furnace that won't ignite through 22°F nights isn't something to leave alone.
- Why won't my furnace pilot light stay lit?
- A pilot that won't stay lit usually means the thermocouple isn't sensing the flame anymore, so the gas valve shuts back off. It can also be a draft blowing the flame out, or a partly clogged pilot orifice starving it of gas. A standing pilot burns gas whether the furnace is heating or not, so this isn't something to leave for later with 8 months of heating season ahead.
