Pilot Light Out? Ignitor Failed? Furnace Repair in Hartsville, TN Fixes It Right

We service both gas and electric furnace systems with manufacturer-trained technicians.

Flat-rate pricing quoted after diagnosis, no pressure toward a premature system replacement.

If you're dealing with a pilot light that won't stay lit, an ignitor that clicks but never catches, or a furnace that runs but blows cold air, you already know furnace failures carry a safety dimension — carbon monoxide and gas leaks — that most other HVAC repairs don't, so the diagnostic has to start there.

Usually a failing ignitor or a fouled flame sensor — both are testable with the right equipment rather than replaced blind.

Could be a delayed ignition fault, a failed gas valve, or a limit switch issue — a full diagnostic narrows it down.

Do you service both gas and electric furnaces?+

Yes — our technicians are trained and certified on both fuel types.

How urgently should I call if I smell gas near my furnace?+

Immediately — leave the area and call, don't attempt to diagnose it yourself.
