Springfield Furnace Repair
Flame Sensor Cleaning & Replacement in Springfield, TN
A furnace that lights, runs for a few minutes, and then shuts off is often telling you one thing: the flame sensor cannot prove the flame is there, so the furnace shuts itself down for safety. Cleaning the sensor fixes many of these calls; when the coating will not come back, replacement is a small, quick job.

What’s included in this visit
Inspect and clean
We remove the sensor, clean it properly, and check the flame signal with a meter — not just by eye.
Replace when needed
If cleaning does not restore a strong signal, we fit the correct replacement sensor for your model.
Check what sooted it
A sensor that soots up again quickly usually has a burner or airflow cause behind it. We check that too, so the fix lasts.
Why Springfield homeowners call us first
- Safety-first gas work. Every gas furnace call includes a heat-exchanger and carbon-monoxide safety check. It is built into the visit, not an upsell.
- Upfront pricing. You approve the price before we touch a wrench. If a repair does not make financial sense, we will tell you that too.
- Same-day and 24/7 response. January cold snaps do not wait for business hours. We run emergency calls around the clock across ZIP 37172 and Robertson County.
- Clean, careful techs. Shoe covers, drop cloths, and a workspace left cleaner than we found it.
Repair or replace? An honest way to decide
| Situation | Our recommendation | Why |
|---|---|---|
| Under ~12 years old, one failed part | Repair | Plenty of life left; repair is the cheaper path |
| Cracked heat exchanger | Replace | A safety issue: cracked exchangers are not repaired |
| 15+ years with frequent breakdowns | Replace | Repair costs stack up fast on an aging unit |
| Sensor soots up again within weeks | Evaluate | We test before guessing, then give you both options |

Frequently Asked Questions
What does a flame sensor actually do?
It proves to the control board that the burner is lit. If it cannot sense the flame, the board shuts the gas off to prevent unburned gas building up.
Can I clean the flame sensor myself?
It is a small part in a gas appliance, and a wrong move can create a gas or electrical risk. It is a quick job for a tech, and we check the flame signal properly while we are there.
How often should a flame sensor be cleaned?
As part of an annual tune-up is a good rule. Homes with dusty air or poor filtration may need it checked more often.
Is a dirty flame sensor dangerous?
The shutdown itself is a safety feature working as designed. The danger is ignoring repeated shutdowns, or bypassing safety controls, instead of fixing the cause.
