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.

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