🔴 If you have an older furnace, strange banging, clanking, and whistling sounds are no strangers to your home. However, if your furnace is relatively new, your unit should be almost completely silent while it operates. Either way, it is not a good sign when your heating unit produces strange sounds. But what is your furnace trying to say?
✔️ Booming: It could indicate the buildup of gas from a delay in the ignition.
✔️ Clicking: This is typically an indication of a faulty flame sensor or a problem between the ignition and the gas. This requires immediate
attention.
✔️ Squealing: Not unlike a car, squealing could indicate a faulty belt or a failing fan motor. Both fixes are usually fairly routine but do require a certified HVAC service technician.
✔️ Rattling: It can come from worn or broken components in the motor or fan. If the rattling worsens, you could be hearing the sound of a complete system failure.
✔️ Chirping: If you hear chirping and it's the beginning of the furnace season, wait a bit. If the chirping doesn't go away, you may need your fan belts replaced or some similar routine maintenance performed.
☎️ If you hear these noises, you should have your furnace inspected by our professional HVAC technicians!
