Call (256) 488-3578What Exhaust Fan Cleaning Covers
Fan Wheel (Impeller)
The fan wheel is the primary component that moves air through the exhaust system. Grease builds up on the blades, reducing airflow and adding weight that stresses the motor bearings. We degrease every blade surface.
Scroll Housing
The curved housing surrounding the fan wheel accumulates grease on all interior surfaces. Cleaned using hot water and chemical degreasers to restore smooth airflow.
Intake Screen & Drain
The intake screen prevents larger debris from entering the fan. The drain at the fan base prevents grease from pooling and overflowing onto the rooftop.
Hinge Kit Installation
Fans without hinge kits cannot be tilted away from the duct opening, limiting access for cleaning. We install hinge kits on fans that require them as part of a comprehensive service.
What does exhaust fan cleaning include?
Fan wheel (impeller) degreasing, scroll housing cleaning, motor compartment exterior wipe-down, intake screen cleaning, and drain check. If a hinge kit is installed, the fan tilts away from the duct opening for full internal cleaning.
What is a hinge kit and does my fan need one?
A hinge kit is a mounting bracket that allows the exhaust fan to tilt away from the duct opening, giving technicians clear access to the duct inlet and the fan's internal components. Without one, cleaning is limited to what can be reached through the fan's access screen. NFPA 96 Section 11.4 requires that exhaust fans be capable of being positioned to allow adequate cleaning.
How often should the exhaust fan be cleaned?
The exhaust fan is part of the complete exhaust system and should be cleaned at the same frequency as the hood: monthly for solid-fuel operations, quarterly for high-volume kitchens, and semi-annually for most restaurants. The fan accumulates grease quickly because all grease-laden air passes through it on the way to the atmosphere.
What happens if the exhaust fan is not cleaned?
A grease-coated fan wheel loses efficiency over time, reducing airflow through the exhaust system. Reduced airflow means more grease reaches the duct walls rather than being captured by filters. In severe cases, a grease-saturated fan can ignite from motor heat or a spark from the duct below.
