Furnace Repair in Rockford, IL

When your furnace won’t start, it can feel overwhelming. But troubleshooting your furnace doesn’t have to be intimidating! With a few simple steps, you may resolve minor issues without calling an HVAC professional.

Common Furnace Issues You Can Troubleshoot

If your furnace won’t turn on, won’t stay on, or won’t ignite, try these steps before calling a professional:

Check the thermostat: Make sure it’s set to “heat” and the temperature is higher than the current room temperature.
Inspect the power: Ensure your furnace has power and circuit breakers haven’t tripped.
Replace the filter: A clogged filter can block airflow and trigger safety switches.
Check the pilot or ignition system: Some furnaces have a pilot light or electronic ignition that may need attention.

These simple checks often fix common issues and may save you a service call.

Furnace Repair Checklist

1. Check the Thermostat

Digital Thermostat:

Replace batteries if the display is blank.
Ensure the switch is set to “heat.”
Confirm the program displays the correct day and time. Use the “hold” function to force the furnace on if needed.
Set the temperature 5 degrees above room temperature.

Smart Thermostat:

Model-specific troubleshooting may be required. Check the manufacturer’s website. If it still doesn’t work, call (815) 914-6197.

2. Examine Breakers and Switches

Locate your main electrical panel (gray metal box in basement, garage, or closet).
Make sure hands and feet are dry before touching breakers.
Reset the furnace breaker if it’s tripped. If it immediately trips again, call a professional.
Confirm any furnace wall switch is in the “on” position.

3. Replace the Air Filter

A dirty filter can cause overheating, higher energy bills, and premature furnace failure.

Locate your filter (blower compartment, attached filter case, or wall-mounted return air grille).
Turn off the furnace, remove the filter, and check it against a light. Replace if it’s dirty.
Flat filters: replace monthly. Pleated filters: every 3 months. Washable filters: every 10 years.

4. Inspect the Condensate Pan

Check for water buildup or overflowing pan.
For PVC drain pipes, ensure they’re clear; use pan-cleaning tablets if needed.
If equipped with a pump, ensure the float switch isn’t stuck. Call (815) 914-6197 if you suspect a faulty pump.

5. Check for Furnace Error Codes

Look for blinking or unusual lights on the furnace.
Any code other than normal indicates a need for professional service.

6. Check Your Fuel Source

Test other gas appliances to ensure your natural gas or propane supply is active.
