Furnace Repair in Charleston: Questions We Hear

Why does my furnace keep shutting off?

Is a cracked heat exchanger dangerous?

Yes. It can leak carbon monoxide into the home. We inspect it on every furnace repair in Charleston.

How long do furnaces last?

Gas furnaces typically run 15 to 20 years with annual service. Electric furnaces can go longer.
