Kitchen Exhaust System vs. Hood Cleaning — UnderstaNDING THE
A Full Kitchen Exhaust System Cleaning
In many kitchens, "HOOD CLEANING" focuses on what’s visible — pressure washing or applying degreaser to hood surfaces.
A complete KECS goes beyond that and addresses the full system — hood interior, baffle filters, ductwork, and rooftop exhaust fan.
A proper cleaning means going through the entire system — the hood, the ductwork, and the exhaust fan on the roof.
When parts of the system are skipped, grease stays behind where you can’t see it — and that’s where problems start.
Commercial Kitchen Exhaust System Cleaning are generally expected to cover the following as part of a thorough, industry-aligned cleaning:
- Preparing and protecting the kitchen before work begins
- Removing, cleaning, and properly reinstalling grease baffle filters
- Cleaning the interior of the hood and plenum — not just exterior surfaces
- Accessing and cleaning ductwork (horizontal and vertical runs)
- Cleaning the rooftop exhaust fan, including blades and housing
- Removing grease buildup from accessible areas throughout the system
- Testing system operation after cleaning
- Cleaning the work area and handling waste properly
- Providing clear documentation of the work performed
Cutting corners might make a service quicker, but it can leave parts of the system unaddressed. A more complete approach helps keep things cleaner, safer to operate, and better prepared for routine inspections.
Hood Cleaning Alone
In many cases, service is focused on visible hood surfaces, typically involving pressure washing or degreaser application to exterior areas.
TYPICAL SCOPE MAY INCLUDE:
- Surface cleaning of hood canopy
- Basic filter rinse or wipe-down
- Limited or no access to ductwork
- Exhaust fan often not serviced
This type of service may improve appearance but can leave portions of the system unaddressed.
