Pilot Light Out? Ignitor Failed? Furnace Repair in Round O, SC Fixes It Right

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

Heat exchanger cracks, ignitor failures, and gas valve issues all fall within our scope.

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, which is exactly why furnace repair calls in Round O, SC get treated with urgency, not a next-available-Tuesday slot.

Before You Call: Furnace Repair Answers

Why does my furnace click but never actually light?+

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

Is a cracked heat exchanger dangerous?+

Yes — it's a genuine carbon monoxide risk and we treat it as a safety issue, not a routine repair line.

Why is my furnace running but blowing cold air?+

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?+

Electric resistance furnaces fail differently than gas units, and we diagnose accordingly.

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

Gas odor calls receive top dispatch priority.

How fast can a furnace tech reach Round O during a cold snap?+
