When You Need Furnace Limit Switch Service

You need limit switch service when your furnace shuts off on its own, runs for a short time and then stops, or will not stay on. A limit switch can fail from age. It can also trip if the furnace is overheating because of a dirty filter, a blocked vent, or a bad blower. We check both the switch and the cause. If the furnace is overheating, we need to fix that too. Otherwise the new switch will trip again. Deer Park homes with older furnaces may have switches that are worn out.

Our Furnace Limit Switch Service Process

We test the limit switch to see if it is working correctly. We also check airflow, the filter, and the blower to make sure the furnace is not overheating. If the switch has failed, we replace it with one that matches your furnace. If overheating is the cause, we fix that first. You get a written estimate before we start. After the repair, we run the furnace and confirm it stays on and heats correctly.

Furnace Limit Switch Cost in Deer Park

The cost depends on whether we replace just the switch or also fix an overheating issue. We give you a written estimate before we start. No hidden fees.
