What’s included in our Commercial Kitchen Exhaust Fan Clean
We don’t just wipe down the outside of your kitchen exhaust fan and move on. We take the unit apart, clean each internal part, and then put it back together. This is the only way to clean an exhaust fan correctly and meet the requirements of AS 1851.
Fan Blades / Impeller
The rotating blades are the primary grease collection surface in the fan unit. Grease builds up on blade surfaces, leading edges, trailing edges, and in the gaps between blades. This buildup creates an imbalance that causes vibration and puts mechanical stress on every connected component. We degrease every blade surface completely, restoring balance and eliminating the vibration that damages your fan over time.
Kitchen Exhaust Fan Housing and Casing
The housing encloses the fan blades and collects grease on all interior surfaces as grease-laden air passes through the unit. Grease on the housing interior restricts the air channel and contributes to reduced airflow. We degrease the entire interior and exterior of the housing, restoring the full air passage.
Kitchen Exhaust Fan Motor
The motor is the most critical component in the fan and the most dangerous when coated in grease. Grease on the motor exterior insulates it, trapping operational heat and causing the motor to run at progressively higher temperatures. This is the primary mechanism by which exhaust fans become fire ignition points. We clean the motor exterior and all surrounding surfaces, restoring proper heat dissipation. We also inspect the motor for signs of overheating, strain, or wear and flag any concerns in your service report.
Kitchen Exhaust Drive Belt and Pulleys
Belt-drive exhaust fans use belts and pulleys to transfer power from the motor to the fan impeller. Grease on belts causes slipping, which reduces the fan's air-moving efficiency and accelerates belt deterioration. Grease on pulleys compounds the problem. We clean and inspect all belts and pulleys, noting any that are worn, cracked, or stretched and need replacement.
Kitchen Exhaust Fan Shaft and Bearings
The shaft connects the motor to the impeller, and the bearings allow it to rotate freely. Grease and debris around these components increase friction, generate heat, and cause premature bearing failure. We clean around the shaft and bearings and check for signs of wear, roughness, or play that indicate bearing deterioration.
Kitchen Grease Cup and Drain
The grease cup collects liquid grease that drains from the fan during operation. If it is not emptied and cleaned regularly, it overflows, sending grease across the rooftop, back into the fan housing, or dripping down through the duct system. We empty, clean, and inspect the grease cup and drain on every service.
Kitchen Exhaust Fan Access Panels and Fan Top
We remove the fan top and all access panels to reach every internal component. For fan units that are not hinged, meaning the fan top must be physically lifted off for access, we can install a hinge fan kit that makes future access significantly easier and faster, reducing service time and cost on every subsequent cleaning.
Commercial Kitchen Rooftop Grease Containment Area
The rooftop area immediately surrounding the exhaust fan accumulates grease spillover from the fan during operation. This grease can spread across the roof surface, creating a slip hazard for anyone accessing the roof and a potential fire risk. We clean the grease containment area around the fan on every service.

Types of Commercial Kitchen Exhaust Fan We Clean
There are differences between exhaust fans. Different types of fans are needed for different types of kitchens, and each type needs a different way to be taken apart, cleaned, and put back together.
Kitchen rooftop exhaust fans (upblast)
are the most common commercial kitchen exhaust fan type, mounted on the roof directly above the duct riser. They pull grease-laden air upward through the duct system and expel it above the roofline. We access these units on the roof, remove the fan top, and clean every internal component.
Inline kitchen exhaust fans and booster fans
are installed within the duct run itself to increase airflow in longer or more complex duct systems. They accumulate grease just like rooftop fans, but are located inside the duct path, often in ceiling spaces or mechanical shafts. We access, disassemble, and degrease inline fans as part of our service.
Utility set exhaust fans
are belt-driven fan and motor assemblies typically used in larger commercial and industrial kitchens. They have additional mechanical components, belts, pulleys, and motor mounts that all require cleaning and inspection. We clean the full assembly and check all drive components.
Direct-drive exhaust fans
have the motor connected directly to the fan impeller with no belt or pulley. They are mechanically simpler but still accumulate heavy grease on blades, motor, and housing that must be removed to prevent overheating and fire risk.
Centrifugal exhaust fans
are used in some commercial configurations for high-volume air movement. Their unique blade geometry, curved blades inside a scroll housing, requires specific cleaning techniques to reach all grease-trapping surfaces.
Hooded exhaust fans
have built-in weather hoods for outdoor rooftop installations. The weather hood and all internal components accumulate grease and require full degreasing during every service.
Our Commercial Kitchen Exhaust Fan Cleaning Process
Cleaning an exhaust fan is more than just cleaning the outside. Before the job is done, the fan must be taken apart, each part cleaned of grease, the mechanical condition checked, and everything put back together and tested. We clean every fan in a certain order.
Step 1: Fan Inspection and Assessment
We thoroughly inspect the fan unit, including blades, motor, housing, and components. Evaluate grease buildup and check for motor strain, bearing wear, and damage. Document the condition with photos and note any necessary repairs.
Step 2: Area Protection
Before cleaning, we cover the rooftop and nearby areas with protective sheeting to prevent grease from contaminating surfaces or drainage systems.
Step 3: Fan Disassembly and Access
We disassemble the fan by removing the top, access panels, guards, and grease cup to access all internal components. For non-hinged fans, we can install a hinged fan kit for easier future cleanings. Complete disassembly is crucial as grease builds up in hard-to-reach areas.
Step 4: Chemical Degreasing
We use a commercial-grade alkaline degreaser on all fan components, allowing it to effectively break down hardened grease. For fans with heavy buildup, we apply extra treatment and longer dwell time before mechanical cleaning. All products are food-safe, eco-friendly, and biodegradable.
Step 5: Scrubbing, Pressure Cleaning, and Extraction
We scrub fan surfaces with stiff-bristle brushes and scraping tools to remove stubborn grease. Then, we use hot water pressure cleaning to eliminate any remaining residue from blades, housing, and motor areas. We thoroughly clean the grease cup, drain, and rooftop containment area, ensuring all grease waste is removed from your property.
Step 6: Reassembly and Function Test
We reassemble the fan components and perform a function test to ensure the fan operates smoothly, with no noise or vibration, and proper airflow. For belt-drive fans, we check belt tension and alignment. If applicable, we confirm the hinge fan kit functions correctly and seals properly.
Step 7: Documentation and Certification
We take before and after photos of all components cleaned. A compliance certificate and service report are provided, detailing what was cleaned, the condition before and after, any mechanical issues found, and the suggested date for your next service based on usage.

Frequently Asked Questions
What are the signs that my exhaust fan needs cleaning?
Common signs your exhaust fan needs cleaning include unusual noises, grease dripping, reduced airflow, increased energy bills, overheating motor, and complaints about heat. Contact us for an inspection if you notice any of these.
Can a dirty exhaust fan cause a kitchen fire?
Yes. Grease on the fan motor can cause overheating and potentially ignite, leading to a fire that spreads through the ductwork. The exhaust fan is the only part where flammable grease meets a heat source.
What is the difference between exhaust fan cleaning and canopy cleaning?
Canopy cleaning covers the visible hood, filters, grease gutters, and lights. Exhaust fan cleaning specifically addresses the mechanical fan unit blades, motor, housing, drive components, grease cup, and rooftop containment. AS 1851 requires both as part of full system maintenance.
Do you clean rooftop exhaust fans?
Yes. We clean all exhaust fan types: rooftop upblast fans, inline fans, utility set fans, centrifugal fans, direct-drive and belt-drive configurations. Rooftop access and fan top removal are included as standard in our service.
Do you provide a compliance certificate after fan cleaning?
Yes. Every service includes a written AS 1851 compliance certificate, a detailed service report, and before-and-after photographs of all fan components. This documentation is ready to present to your insurer, council inspector, or auditor.
Is exhaust fan cleaning included in your duct cleaning service?
Yes. Our full system duct cleaning service covers the ductwork, plenum, and the exhaust fan as part of a complete rooftop-to-cooktop clean. Exhaust fan cleaning can also be booked as a standalone service if your fan needs attention between full system cleans.
Can you clean exhaust fans outside business hours?
Yes. We offer evening, overnight, and weekend scheduling as standard. Your kitchen needs to be offline for safe fan cleaning, so we always work outside your operating hours.
Will cleaning my exhaust fan reduce my energy bills?
Yes. A clean fan operates more efficiently, uses less energy, and reduces electricity costs. In kitchen cleaning, the heavily greased fans can lead to substantial energy savings.
