Troubleshooting Noisy Commercial Exhaust Hoods

Uh-oh. Something sounds off in your commercial kitchen. And while a busy kitchen can certainly get loud from time to time, there is one thing no restaurant owner wants to hear – a noisy commercial exhaust hood. Don't let those clanks and rattles disrupt your dinner service. Here, we'll walk you through the essential steps to troubleshoot and address the issue, to keep things running smoothly - and quietly!


Identify the Source of the Noise

The first step in silencing your noisy exhaust hood is pinpointing the source of the problem. Often, the noise stems from components that have loosened over time or debris that's found its way into the system. Carefully inspect the fan blades, motor, and ductwork for any signs of damage, misalignment, or foreign objects.


Check for Loose Parts

Loose parts can create some alarming sounds in your kitchen. Give your exhaust hood a thorough examination, paying close attention to screws, bolts, and brackets. Tighten any components that seem to have come loose. A simple adjustment might be all it takes to restore peace and quiet.


Clean and Lubricate

Regular cleaning and lubrication can work wonders in reducing noise. Over time, grease and dirt can accumulate in the fan and motor assembly, causing friction and vibrations. Disconnect the power, and with a gentle touch, clean the fan blades, motor, and surrounding areas. Once clean, apply a suitable lubricant to minimize friction and noise.


Inspect the Ductwork

Damaged or improperly installed ductwork can contribute to disruptive noise. Check for any visible cracks, gaps, or loose connections along the ducts. Seal any openings with appropriate materials and ensure the ductwork is securely fastened.


Schedule Professional Maintenance

If the noise persists despite your efforts, it might be time to call in the professionals. Regular maintenance by experienced technicians can prevent issues and keep your exhaust hood operating smoothly. It also ensures compliance with your local health and safety inspectors.


Preventing Future Noise

Once your exhaust hood is has been quieted, take preventive measures to avoid future disturbances. Regularly inspect and tighten components, maintain cleanliness, and schedule routine professional maintenance to keep your kitchen environment peaceful and productive.


Don't let a noisy exhaust hood disrupt the harmony of your kitchen. By identifying the source, performing maintenance, and seeking professional help when needed, you can enjoy a quiet and efficient culinary space once again.
