Troubleshooting Furnace Noises in South Jordan, UT

If your furnace is making strange or loud noises in South Jordan, UT, don’t ignore it — unusual sounds can be signs of serious HVAC issues. From rattling and banging to screeching or clicking, different furnace noises often point to different problems. Here’s what you should know about the most common furnace sounds and when it’s time to call for furnace repair.

Common Furnace Noises & What They Mean

1. Banging or Popping

Often caused by dirty burners or delayed ignition. Gas buildup can create a small explosion when the furnace finally lights. This can be dangerous and should be checked immediately.

2. Rattling

Loose panels, screws, or ductwork can rattle as the furnace runs. While sometimes minor, consistent rattling should be inspected to avoid long-term wear.

3. Screeching or Squealing

This high-pitched sound is usually due to a worn blower belt, bad motor bearings, or issues with the fan. These parts may need lubrication or replacement.

4. Clicking

Clicking during startup can be normal, but constant clicking may indicate a faulty igniter, relay, or control board. If your furnace clicks but doesn’t ignite, call a pro.

5. Booming

A loud boom or thud when the furnace turns on could signal a dangerous ignition delay or ductwork expansion. This should be diagnosed by a licensed technician.

What You Can Do

Before calling for help, you can:

• Check your furnace filter — a clogged filter can cause airflow issues and noise
• Inspect vent covers and duct openings for obstructions
• Ensure all access panels are tightly secured

If the noise continues or worsens, it’s time for professional service.
