Elizabethtown asks a lot of a furnace
October through April, seven months of the year, your furnace is what keeps the house livable. Winter nights average 27°F here, cold enough that the burner is cycling on and off for hours at a stretch most nights of the week. Every one of those starts puts wear on the igniter and the parts that get the burner lit. When the igniter finally gives out, the furnace won't fire at all and the house starts cooling down.
Most homes in Hardin County heat with electricity, so when the power goes, the heat goes with it. That is not rare here. Nearly a quarter of Kentucky households lost power for 24 hours or more in 2024, and the last ten years brought 17 winter storms and 74 damaging wind events to this area. A furnace that was already struggling with a weak igniter or a failing part often doesn't come back cleanly once the power is restored.

Kentucky requires HVAC contractors to hold a state license.
The license comes from the Department of Housing, Buildings and Construction, and it belongs to the contractor rather than to each job. That means the state tested this contractor and licensed the business, not this one furnace repair specifically.
For a furnace repair, that license is what stands behind the work in Hardin County. A furnace burns gas, and a bad connection at the burner or the gas line is the part of the job that can hurt someone. The license means the state has tested and keeps a record of the contractor doing that work.

- Why won't my furnace turn on?
- The most common reason is the thermostat isn't calling for heat the way it should, whether that's dead batteries, a tripped breaker, or a setting that got bumped. After that, check the furnace switch, which looks like a light switch near the unit, and the door panel, which has to be seated all the way for the furnace to run at all. If power and settings check out, the problem is likely inside the unit, in the ignition system or a safety switch that's shutting it down before it starts. A contractor can test each part and find which one is stopping it.
- Why is my furnace blowing cold air?
- Most of the time this means the blower is running but the burners haven't lit, so air is moving through the ducts without any heat added to it. A dirty flame sensor is a frequent cause, since it can't detect the flame and shuts the gas off as a safety measure. It can also mean the igniter is failing or the furnace is stuck in a startup cycle it can't complete. With nights here averaging 27°F in the winter, cold air blowing instead of heat is worth having looked at the same day.
- Why won't my furnace pilot light stay lit?
- This usually points to the thermocouple, the small part that senses the pilot flame and keeps gas flowing to it. When the thermocouple wears out or sits out of position, it can't confirm the flame is lit, so the gas valve closes and the pilot goes out. A draft reaching the pilot or a partly clogged pilot tube can cause the same thing. A contractor can tell which one it is and replace the part that's failing.
