Common Furnace Noises in Puyallup and What They Say About Your HVAC

common furnace noises puyallupNo HVAC is completely silent during operation, not even modern ductless heaters. In newer models, the sound is a quiet and even hum. If you notice irregular furnace noise, should you be alarmed? Familiarize yourself with the different sounds and what they say about the furnace’s health. Rest assured that common furnace noises are normal.

Be Mindful of These Furnace Noises

Grinding – A grinding sound of metal to metal may be a sign of an internal part coming loose. This can lead to further damage if not addressed.

Squeal – If you hear a squeaking sound or a continuous screech, there may be a cracked belt below the blower assembly. A worn belt can result in significant loss of heating power.

Rumbling – If you hear a loud bang in a gas furnace, the fuel is likely not burning properly. The gas is igniting all at once instead of steadily and evenly. This is a safety hazard; we suggest shutting off the system and calling an inspector ASAP. Though rare, the gas not igniting properly can cause a fire or an explosion.

Rattling – The furnace rattling and vibrating may be an indicator of a loose blower motor. There may also be one or more loose bolts in the access hatch. The bolts may not have been properly tightened the last time the hatch was opened and then shut.

When to Replace Your Furnace

The above noises are more common in older gas furnaces. While we can diagnose and repair most issues, we usually recommend replacement if the furnace is more than 20 years old. If repairing an older furnace, it’s usually only a matter of a few years before another problem creeps up.
