Why Are Strange Sounds Coming from My Commercial HVAC?

Why Are Strange Sounds Coming from My Commercial HVAC?

December 15, 2022

Most commercial HVAC systems operate quietly. If yours starts producing strange sounds, there is a high likelihood that something is wrong. Below are unusual sounds that could come from your commercial HVAC system and what they mean in Boston, MA.

Screeching and Squealing

Your HVAC system contains multiple moving parts, such as motor bearings and belts. You may hear squealing and screeching when these parts start wearing out. Worn-out parts reduce efficiency and may cause your system to run without stopping.

Consider scheduling a maintenance appointment to keep your HVAC system running optimally. A technician will lubricate all moving parts and replace worn-out components during the appointment.

Banging Noises

When one of your HVAC components becomes loose, it’ll start hitting against the moving parts. Consequently, you and your employees may hear loud banging or metal-on-metal noises. Consider shutting down your system to prevent further damage and expensive repairs.

Whistling Noises

Your ductwork and vents help to distribute cool and heated air into your commercial facility. If you place machines or office furniture too close to the vents, it will restrict airflow.

The same can be said for excess dirt and debris. Consequently, you may hear whistling noises as air struggles to enter your building. Consider moving any objects away from the vents.

Hissing and Gurgling Sounds

If your HVAC system uses an R-410a refrigerant, the fluid could leak, causing other unusual sounds. Refrigerant helps to transfer heat. A leakage causes its levels to drop, making it difficult for your HVAC system to move heat efficiently.

The system may start running continuously, increasing wear and tear and your monthly energy bills. Allow a trusted HVAC company to repair the leaks, as this particular fluid could harm you or your co-workers if anyone comes in contact with it.
