Seven months of work takes its toll
Your furnace in Springfield runs October through April, seven months of the year. On nights that average 30°F through December through February, it cycles on and off for hours at a stretch, and every start puts wear on the igniter and the parts that get the burner lit.
Most homes here heat with electricity, so when the power goes out, the furnace stops with it. Robertson County has seen 11 winter storms and 126 damaging wind events over the past ten years, and 20% of Tennessee households went at least 24 hours without power in 2024. A furnace that was already struggling can fail to restart once the power comes back on.

- Why won't my furnace turn on?
- Most often the thermostat isn't calling for heat the way it should, or power isn't reaching the furnace. Check that the thermostat is set below room temperature and has fresh batteries if it uses them. Next check the furnace switch, the one that looks like a light switch near the unit, and the breaker for it in the panel. If those are fine, the igniter or the flame sensor may have failed, and a contractor will need to test them to know for sure.
- Why is my furnace blowing cold air?
- Cold air usually means the blower is running but the burners haven't lit. That points to a failed igniter, a dirty flame sensor, or a gas supply problem. It can also mean the furnace is in the middle of its normal cycle, running the blower a few seconds before or after the burners fire. If the air stays cold for more than a few minutes, the burners aren't lighting and a contractor should look at it, especially with winter lows here averaging 30°F.
- Why won't my furnace pilot light stay lit?
- A pilot light that won't stay lit is almost always a worn thermocouple. That's the small metal rod that sits in the pilot flame and tells the gas valve the flame is real. Once it wears out it can't hold the signal, so the valve shuts the gas off even though the pilot was burning fine a moment before. It can also mean a draft is blowing the flame out or the pilot orifice is dirty, but a thermocouple is the more common cause and a contractor can replace one directly.
