Exhaust Fan Cleaning

Exhaust Fan Cleaning

Restore Proper Airflow • Reduce Fire Risk • Improve Kitchen Safety & Efficiency

Your kitchen’s exhaust fan is the driving force behind your entire ventilation system. Without it, smoke, heat, steam, and airborne grease have nowhere to go, causing them to linger inside your kitchen and create an uncomfortable—and potentially unsafe—environment. The exhaust fan plays a vital role in removing contaminated air and pushing it safely outside, keeping your kitchen cool, clean, and compliant with ventilation standards.

However, because the exhaust fan is located at the end of your ventilation pathway—typically on the rooftop or an exterior wall—it receives some of the heaviest grease accumulation in the entire system. As grease, dust, and airborne fats make their way up through the hood and ductwork, they settle on the fan blades, fan housing, and motor components. Over time, this buildup becomes thick, sticky, and hazardous, putting strain on the fan’s performance and increasing your risk of mechanical failure or fire.

At Aurora Kitchen Hood Cleaning, our Exhaust Fan Cleaning service is designed to ensure your fan operates safely, efficiently, and reliably. We use specialized tools, professional-grade degreasers, and NFPA 96–compliant cleaning methods to remove grease buildup, restore airflow, and extend the lifespan of your equipment. Whether your fan is rooftop-mounted, wall-mounted, or part of a more complex ventilation system, we clean it thoroughly and correctly—every time.

Why Exhaust Fan Cleaning Is Essential

Many commercial kitchen operators focus primarily on hood canopies and filters, but the exhaust fan is just as important—if not more. This is the final point where grease lands before air is expelled outside, making it one of the dirtiest and most grease-prone components of your ventilation system.

When the exhaust fan is neglected, it can lead to a variety of problems:

Loss of Airflow and Reduced Ventilation Efficiency

Grease buildup on blades and inside the housing weighs the fan down, reducing RPMs and decreasing the amount of air it can move.

Overheating of the Fan Motor

When the fan works harder due to blockage or grease weight, the motor can overheat and fail prematurely.

Loud Vibrations and Noise

Unbalanced blades caused by uneven grease deposits can lead to rattling, shaking, and excessive noise.

Increased Energy Consumption

A struggling fan uses more power, leading to higher utility bills.

Fire Hazards

Dense grease deposits inside the fan can ignite instantly if exposed to high heat or flames traveling up the duct system.

Shortened Equipment Lifespan

Unmaintained fans wear out faster, leading to costly replacements or repairs.

A clean exhaust fan ensures proper ventilation, reduces hazards, and keeps your kitchen working at peak performance. This is why NFPA 96 includes the exhaust fan in its mandatory cleaning standards.

Our Exhaust Fan Cleaning Process

We follow a detailed, multi-step cleaning process to ensure your exhaust fan is thoroughly cleaned, inspected, and restored to optimal performance. Our technicians are trained to handle all types of fan systems, ensuring safe and compliant service.

Initial Inspection

We begin by examining the fan’s overall condition to identify grease accumulation, mechanical issues, or structural concerns. This step helps us determine whether the fan needs balancing, repair, or deeper cleaning.

Safe Shutdown & Disassembly

When accessible, we loosen or remove the fan from its housing to allow full cleaning of the blades, housing, motor area, and fan shroud. We ensure all electrical components are safely protected during the cleaning process.

Grease Removal & Deep Cleaning

We remove heavy grease deposits manually, then apply industrial-strength degreasers to break down stubborn residue. The fan blades, housings, and accessible motor components are cleaned to bare metal, restoring proper airflow and balancing.

Motor & Component Cleaning

We clean accessible motor areas, cooling vents, and wiring housings to prevent overheating caused by grease and dust buildup.

Inspection of Belts, Bearings, and Hardware

We examine belts for wear, check bearings for smooth rotation, and inspect all mounting hardware. Identifying early signs of mechanical issues can prevent unexpected breakdowns.

Alignment & Balancing (When Applicable)

If the fan shows signs of wobbling or vibration, we perform balancing checks to ensure smooth operation. Proper balancing prevents motor strain and reduces noise.

Cleaning of Rooftop or Wall-Mounted Bases

We remove grease from the mounting base, hinge kit area, and surrounding surfaces to prevent roof damage, corrosion, and environmental hazards.

Reassembly & Performance Testing

Once fully cleaned and reassembled, we test the fan to ensure it operates correctly, runs quietly, and moves air efficiently.

This comprehensive process ensures your exhaust fan is not only clean, but functioning better than before.

Signs Your Exhaust Fan Needs Cleaning

You may need exhaust fan cleaning if you notice:

• Excessive smoke lingering in the kitchen

• Loud noises or vibrations from the fan

• Poor airflow, even with the fan running

• Strong cooking odors that don’t dissipate

• Fan turning slowly or struggling to start

• Heat buildup in the cooking area

• Frequent motor failures or electrical issues

• Visible grease dripping from the fan or housing

If your fan shows any of these symptoms, cleaning is urgently needed to prevent damage or safety risks.
