Milford furnaces work seven months straight
October through April, your furnace is what stands between you and a 25°F night. That is seven months of the burner lighting and shutting off, over and over, every day. Each cycle puts a little more wear on the igniter and the parts that control the flame.
Clermont County has logged 13 winter storms and 143 damaging wind events over the past ten years, and 48.6% of homes here heat with electricity. When the power goes out, an electric furnace stops working the moment it does. If yours has been slow to start or shutting off on its own, that is often the first sign something is giving out.

In Ohio, HVAC licensing for homes is left to the counties.
Clermont County sets its own rule for who can do HVAC work on a house, since Ohio leaves that to the counties instead of running a state license. That means there is no single license to check here, and what applies depends on the county's own rule rather than a state test. Ohio does define a home contractor as someone carrying at least $250,000 in liability insurance. That is part of the state's definition of a home contractor, not a license or a test anyone passed.
For a furnace repair, that leaves the insurance figure as the one fixed fact from the state itself. Ohio requires it as part of what a home contractor is, wherever the job is done. Everything beyond that, whether someone can do this work at all, comes from Clermont County's own rule rather than anything set in Columbus.

- Why won't my furnace turn on?
- Start with the thermostat. Make sure it's set to heat and the temperature is set above the room temperature, and check that it has power or fresh batteries. If the thermostat looks fine, check your breaker panel, since a tripped breaker will cut power to the whole system. Furnaces also won't start if the air filter is badly clogged or if a safety switch on the furnace itself has been triggered. If none of that brings it back on, a contractor can test the ignition system and controls to find out what's failing.
- Why is my furnace blowing cold air?
- Most often this means the furnace is running the blower but the burners haven't lit. That can happen because of a dirty flame sensor, a failed igniter, or a gas supply issue. It can also mean the thermostat fan setting is on "on" instead of "auto", which pushes air through the vents even when the burners aren't firing. If your air stays cold for more than a few minutes after the furnace starts, turn it off and have a contractor look at the ignition components before running it again.
- Why won't my furnace pilot light stay lit?
- This usually points to the thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out or sits out of position, it shuts the gas off even though the flame is lit. A draft in the area or a dirty pilot orifice can also blow the flame out or keep it too weak to hold. Since this involves the gas valve, it's worth having a contractor check it rather than repeatedly relighting it yourself.
