Common Furnace Problems We Repair
No heat or insufficient heat, often caused by ignition failure, a faulty flame sensor, or a tripped limit switch.
Short-cycling, where the furnace turns on and off rapidly, frequently linked to overheating, a dirty flame sensor, or an airflow restriction.
Blower motor issues, including a blower that runs continuously or fails to start.
Unusual noises such as banging, rattling, or screeching, which can indicate a cracked heat exchanger, loose components, or a failing inducer motor.
Pilot and ignition problems on older furnaces, and intermittent ignition on newer electronic models.
What Our Furnace Repair Service Includes
A technician performs a full diagnostic of the furnace, identifies the failed component, and explains the repair scope before any work begins. You approve the repair before the technician proceeds.
Common repairs include flame sensor cleaning or replacement, igniter replacement, limit switch and pressure switch replacement, blower motor and capacitor service, thermostat communication checks, and airflow verification.
When to Call for Professional Furnace Repair
Call for service if the furnace is not producing heat, is short-cycling, is making loud or unusual noises, or is showing error codes on the control board.
If you smell gas or suspect a carbon monoxide leak, leave the building immediately, call your gas utility or 911, and do not attempt to operate the furnace. After the immediate hazard is cleared, request professional furnace repair.
