Furnace Repair in Lexington: Questions We Hear

Why does my furnace keep shutting off?

Short cycling is usually a dirty filter, a failing flame sensor, an oversized furnace or a limit switch tripping from restricted airflow.

Is a cracked heat exchanger dangerous?

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

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