About Us

What Furnace Repairs Do We Handle?

Our Rockford HVAC team is fully equipped to repair any furnace issue, including:

  • Ignitor & Flame Sensor Issues: Failed ignitors are the most common furnace problem we see. When your ignitor stops working, your furnace won't heat. We replace worn ignitors and clean dirty flame sensors that prevent your burners from lighting, restoring heat quickly and safely.

  • Thermostat Problems: From dead batteries to faulty wiring and calibration issues, thermostat problems prevent your furnace from responding to temperature adjustments. We diagnose and repair all thermostat issues to restore proper temperature control throughout your home.

  • Blower Motor & Fan Repairs: When your blower motor fails, you'll have no airflow from your vents even if the furnace is running. We repair or replace worn blower motors, failed capacitors, and broken blower belts in older models. Our repairs restore proper airflow and even heating throughout your home.

  • Gas Valve & Pilot Light Repairs: For older furnaces with pilot lights, we repair faulty thermocouples, clean dirty pilot orifices, and adjust gas pressure. Gas valve problems require professional attention, we ensure your furnace operates safely and efficiently.

  • Control Board Replacement: The control board is your furnace's brain. When it fails, your furnace won't turn on or may shut off unexpectedly. We diagnose control board failures and replace them with manufacturer-approved parts to restore reliable operation.

  • Heat Exchanger & Safety Issues: Cracked heat exchangers pose serious carbon monoxide risks and typically mean furnace replacement. We inspect heat exchangers thoroughly, test all safety controls, and provide honest recommendations about repair versus replacement.

  • Ductwork & Airflow Problems: Uneven heating, poor airflow, and excessive noise often indicate ductwork issues. We inspect your entire system to identify disconnected ducts, leaks, or blockages affecting your furnace's performance.

Common Signs You Need Furnace Repair

If you notice any of these warning signs, don't wait, call Gilley's for professional diagnosis and repair:

  • Weak or No Airflow: Rooms staying cold while furnace runs indicates blower motor problems, clogged filters, or ductwork issues requiring professional attention.

    Strange Noises: Banging at startup, screeching from worn bearings, or rattling sounds all signal component failures that will worsen without repair.

    Frequent Cycling: Your furnace turning on and off every 5-10 minutes instead of running steady cycles shows thermostat or flame sensor problems.

    Rising Energy Bills: Heating costs increasing 20%+ compared to previous winters without temperature changes indicates efficiency loss from failing components.

    Uneven Heating: Some rooms staying significantly colder despite thermostat settings suggests ductwork leaks, blower issues, or system imbalances.

Ignoring these warning signs can lead to complete system failure during the coldest nights. Our technicians can inspect, diagnose, and fix the issue before it turns into an emergency.
