5 HVAC System Sounds You Don’t Want to Hear

Are you hearing strange noises from the HVAC system in your American Fork, Utah, home? While some noise is typical as your unit ages, there are some noises that can spell trouble for your system. If you hear any of the HVAC noises listed below, it could be time to place a call to your HVAC technician. 

1. Rumbling

Rumbling noises coming from your furnace are often a sign that there is a problem with the burner. Typically, this noise occurs when the burner is dirty. As your HVAC system works to push out heat, it will begin to build up dirt and soot on the burners. When this buildup occurs, it can cause restrictions in the airflow, leading to a rumbling noise when it is running. 

2. Booming

While a booming sound in any appliance is never a good sign, with an older HVAC system, it could be a warning of a dangerous situation. Unfortunately, this noise is often ignored as it usually happens once or twice and then stops. The booming you are hearing is likely a delay with the ignition, which is causing the gas to accumulate. This situation can turn dangerous rather quickly and requires immediate investigation by an HVAC specialist.

3. Squealing

Squealing noises can be very irritating, but they are a good warning sign that your unit is in need of repair. Most often, a squealing noise is associated with a worn or frayed belt or damaged motor bearings. It also could be a sign that the unit is in need of lubrication. These issues are critical to address immediately as a broken belt can quickly stop your blower, resulting in a breakdown. 

4. Banging or Thumping

Any type of metal-on-metal noise or thumping is often related to the blower assembly in your unit or the system motor and indicates that parts of these components have become loose. If the noises are left unaddressed and continue to get louder, then it is likely that one of the parts has broken or is disconnected and is loose in the system. Eventually, your system will shut itself off if not repaired. 

5. Clicking

When your unit turns on and off, it will typically be accompanied by a few clicks. Yet, if the clicking continues or suddenly begins repeating, you could either have a problem related to a defective relay or the electrical controls that have led to the relay failure.
