Before cold weather sets in, check your furnace. Finding out whether you need furnace repairs and getting it done now helps avoid heating system problems later. You can handle some issues below yourself, while others require a heating contractor’s services.

How to Tell You Need Furnace Repairs

1. Unlit Pilot Light

A pilot light that doesn’t come on or stay lit prevents the furnace from operating. The cause could be a draft, clogged system, faulty ignition, or damaged thermocouple—a safety device.

2. Loud Noises

Your furnace should deliver warmth quietly. Rumbles and rattles can mean a clogged burner, reduced airflow, or mechanical problems.

3. Scraping Sounds

A scraping sound is your signal to turn off the furnace and call a professional heating contractor. The ball bearings are likely worn and can cause severe damage to the furnace.

4. Dirty Filter

A dirty filter means less air flows through the system, which forces the furnace to work harder. If the screen looks gray and you can’t see through it, install a new one.

5. Continuous Blowing

When the blower doesn’t shut off, a faulty limit switch might be the culprit. A professional heating contractor should check it out.

6. No Heat

When the pilot light works but there’s no heat, check the thermostat. You might need a new device, but try installing a fresh battery first.

7. Not Enough Heat

If the system isn’t generating enough warmth, ensure the thermostat is set to “heat.” If the settings are correct, the furnace may be too small for your space and not deliver the heat you want.

8. Furnace Works But Stops

When your furnace starts working but stops, and the thermostat display blanks out, check the power cord for a secure connection. Other possible problems could be a blown fuse or a tripped circuit breaker.

9. Yellow Pilot Light

A yellow or flickering pilot light flame in a gas furnace means too much carbon monoxide is in the mix. Call a furnace repair expert to make an adjustment.

10. Normal Wear & Tear

With regular maintenance, a furnace can last between 16 and 20 years. If your unit is approaching that age, consider investing in a new energy-efficient system.
