Before You Call: Furnace Repair Answers

Why does my furnace click but never actually light?+

A clicking-but-not-lighting pattern is one of the most common furnace complaints we diagnose.

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?+

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

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

No-heat calls during freeze warnings are prioritized across Festus, MO.
