made practical.
A plain-language overview of the commercial kitchen exhaust system, why inspection timing matters, and what useful service documentation should show.
The complete system
Clean beyond what the customer can see.
The visible hood is only the beginning. Grease-laden vapor travels through an interconnected exhaust path, so the accessible system must be evaluated as a whole.

Why access matters: Panels, fan access, equipment condition, and site limitations can affect which portions can be reached and documented during service.
General inspection timing
The kitchen determines the interval.
Cooking fuel, volume, menu, operating hours, and the rate of grease accumulation all affect how often a system should be inspected.

Important distinction
Inspection timing is not an automatic cleaning promise.
These are general inspection categories commonly associated with NFPA 96. When an inspection identifies contamination that requires removal, the affected accessible portions should be cleaned. The applicable edition, local requirements, system condition, and direction from the authority having jurisdiction control.
After the work
Documentation should explain more than “completed.”
A useful closeout record helps the operator understand what was serviced, what was observed, and what requires attention next.
- Agreed scope and accessible components
- Before-and-after photo record
- Observed system conditions
- Inaccessible or uncompleted areas
- Completion labeling and next service window
Questions worth asking
Before your next exhaust-system service.
What is included?
Confirm the hood, filters, accessible ductwork, exhaust fan, rooftop area, and any stated exclusions.
What cannot be reached?
Ask how access limitations will be identified, photographed, and reported.
What record will I receive?
Know whether the closeout includes photos, observations, labeling, and the recommended next service window.
