Furnace Repair
Expert furnace repair services to restore heating quickly and safely, with proper diagnosis of gas and electric systems.
Common furnace problems
Furnace issues can leave your home cold and uncomfortable, especially during extreme winter weather. Common problems include the furnace failing to start, blowing cold air, short cycling, running constantly without satisfying the thermostat, and unusual noises or odors. Our technicians diagnose and repair all types of gas and electric furnaces.
Some furnace problems pose safety risks that require immediate attention. Gas odors, signs of carbon monoxide, and visible flames or smoke are emergencies that should be addressed immediately. If you suspect a gas leak or carbon monoxide issue, evacuate the building and call for emergency service.
Diagnostic process
Our furnace diagnostic process begins with a visual inspection of the equipment, checking for signs of damage, corrosion, or improper operation. We verify gas pressure, check electrical connections, measure temperature rise across the heat exchanger, inspect the burner assembly, and test safety controls.
For gas furnaces, we check the heat exchanger for cracks that could allow carbon monoxide to enter the home. This is a critical safety check that should be performed annually. We also inspect the venting system for blockages or improper installation that could affect safe operation.
Common repairs
Ignition system failures are among the most common furnace problems. Whether your furnace uses a standing pilot, intermittent pilot, or hot surface igniter, we can diagnose and repair ignition issues to restore reliable starting. Flame sensor problems are also common and can cause the furnace to cycle on and off repeatedly.
Other frequent repairs include replacing failed blower motors, capacitors, limit switches, pressure switches, and gas valves. We carry a comprehensive inventory of parts to complete most repairs on the first visit, minimizing your time without heat.
Preventive maintenance
Regular furnace maintenance prevents many common problems and extends equipment life. Annual inspection and cleaning includes checking and cleaning the burner assembly, replacing the air filter, lubricating the blower motor, testing safety controls, and verifying proper operation.
Changing your air filter regularly is the single most important maintenance task you can perform between professional service visits. A dirty filter restricts airflow, reducing efficiency and potentially causing the furnace to overheat. We recommend checking filters monthly and replacing them every one to three months.
