Furnace Repair

A furnace blowing cold air can be caused by a failed igniter, a bad control board, a tripped safety switch, or a malfunctioning blower motor. A professional technician can diagnose the exact cause and recommend the right repair.

Signs of a failing blower motor include weak airflow, unusual noises like squealing or rattling, the motor running but not blowing air, or the system overheating and shutting down frequently.

It depends on the issue. If you smell gas, hear unusual noises, or see the system cycling on and off rapidly, shut it off and call a professional immediately. Running a malfunctioning furnace can be a safety hazard.

A loud bang when the furnace starts usually means delayed ignition caused by dirty burners or a faulty igniter. This can be dangerous and should be addressed by a professional right away.

A hot surface igniter is the component that lights the gas in your furnace. It glows red-hot to ignite the burners. They are fragile and wear out over time, making them one of the most common furnace repairs.

Most gas furnaces in North Texas last 15 to 20 years with proper maintenance. Since Texas winters are relatively mild, furnaces here often last longer than in colder climates.

A furnace control board typically lasts 10 to 20 years, but power surges, moisture, and general wear can shorten its lifespan. If your furnace shows error codes or behaves erratically, the control board may need replacement.

Standard 1-inch filters should be replaced every 1 to 3 months. Thicker media filters can last 6 to 12 months. A dirty filter restricts airflow and makes your system work harder, leading to higher bills and faster wear.
