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?+

This symptom shouldn't be ignored since it sometimes points to a safety-related fault.

Do you service both gas and electric furnaces?+

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

Gas odor calls receive top dispatch priority.

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