Furnace Repair Done Right, Every Time

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 Duncanville during a cold snap?+

Call dispatch for a live arrival estimate based on current demand.
