Common Furnace Problems
Most furnace repair in Fort Worth traces back to one of these.
- Clicks but won't light: often a cracked ignitor.
- Lights, then shuts off: usually a dirty flame sensor or a tripped limit switch.
- Runs but blows cold: a pilot or ignition problem, or a clogged filter tripping the limit switch.
- Loud squeal or no airflow: the blower motor or its capacitor.

Why Winter Repairs Pile Up
Fort Worth heats for a short season, so furnaces sit idle for months and problems show up on the first cold night. In February 2021, DFW Airport hit -2°F during the historic winter storm, according to the National Weather Service. A fall check of the ignitor, flame sensor and venting is cheaper than a call during a freeze.
