Different noises coming from a furnace may be the unit’s standard start-up and shut-down sounds. However, they may also indicate something is wrong. In either case, it’s essential to know what each sound means to take care of any issues quickly and make your home comfortable again as soon as possible. This blog discusses all of these and provides information on working with residential and commercial air conditioning repair contractors in Peoria, Arizona.

Common Furnace Noises and What They Mean
Whirring
This is usually the most common sound you’ll hear from your furnace, which means the blower motor has turned on. The whirring should be quiet and last 30-60 seconds before shutting off.

Squealing
If you hear a high-pitched squeal coming from your furnace, it could mean that one of its belts or bearings needs to be replaced. It’s essential to get this looked at as soon as possible since these components are integral in keeping your system running efficiently and safely.

Popping
If you’re hearing popping noises from the furnace, it may indicate an issue with how much gas is supplied during combustion. An inadequate gas supply can cause incomplete burning, leading to dangerous carbon monoxide buildup in your home. Make sure you have an HVAC technician inspect this immediately.

Banging and Clanking
Banging and clanking noises signify that something isn’t functioning correctly within the burner assembly. These could be due to debris buildup or loose parts rattling around inside when the furnace is starting up or shutting down. Be sure to have an expert take care of this quickly so there won’t be further damage done to the unit itself. If neglected, it can lead to dirt accumulation near sensitive components like thermocouples or thermopiles.

Rattling
Rattling sounds typically signal a loose part inside the system. For example, one of the screws might have become undone during operation, causing vibration when spinning at high speeds for extended periods. Ensure all bolts are tightened securely according to their manufacturer specs before operating again if necessary.

Troubleshooting Tips for HVAC Noise Issues
When trying to troubleshoot any HVAC noise issue, make sure you start by cleaning or replacing the filters first. Then check for any moving parts that need lubrication, tightening loose parts and securing or replacing belts if required. Finally, inspect your ductwork for any blockages or damage causing the sound. Having a professional take care of this type of maintenance is always a good idea.
