5 Furnace Noises You Shouldn’t Ignore

 

Do you hear a strange noise coming from your furnace? This unit normally produces sound when it is turned on and off, but the rumbling, rattling or clicking sounds are not part of your furnace’s normal operation. Make sure to look into these five (5) furnaces noises that should be addressed immediately.

Clicking

If you hear a clicking noise from the furnace, it explains one thing – a faulty flame sensor. In some instances, the problem might be caused by the vibration of the ducts and other parts of the system. The noise may also indicate an issue in the oil or gas ignition.

Rattling

Does your furnace produce a rattling sound when it turns on? This is an indication of a damaged or worn-out component on the fan or motor of the unit. In other cases, this noise is a sign of carbon monoxide issue. Ask your HVAC contractor to conduct an assessment on every part of your heating system including the heat exchanger.

Booming

Older furnaces commonly produce a booming sound due to gas build-up. When the ignition process is interrupted, most likely, the air ducts are contracting or expanding. Delayed ignition is common on gas furnaces which can lead to a mini-explosion effect if not handled carefully. A delay in the ignition is commonly caused by insufficient gas, impaired pilot light, and dirty or blocked gas burners.

Chirping

If your furnace has not been used for a long time, the unit may start producing a chirping noise. And it is something you do not want to hear in the middle of the cold nights. The strain in the blower wheel possibly causes the high-pitched chirping sound in your furnace. Get this problem fixed as soon as you notice it.

Squealing

The high-pitched and repeated squeal in your furnace is an indication of worn-out belts. If the issues are the belts or bearings, they only need lubrication to function properly. Make sure to provide the belts, bearings and other internal parts the right amount of lubrication to avoid friction.
