Exhaust Duct Cleaning
NFPA 96 Compliant • Fire-Safety Focused • Complete System Cleaning from Hood to Fan
Your kitchen’s exhaust ducts are one of the most crucial components of your entire ventilation system, yet they are often the most overlooked. While the hood canopy and baffle filters catch the visible grease you can see, the ductwork hidden behind walls, ceilings, and structural components collects the heaviest and most dangerous grease buildup. Because the ducts are out of sight, they are frequently neglected—until a major issue occurs.
Grease inside the exhaust ducts is highly flammable. Even a small flare-up at the cookline can ignite residues inside the ductwork, allowing flames to spread rapidly throughout the system. This is how many commercial kitchen fires expand beyond control. Exhaust ducts that are not cleaned regularly pose serious risks to your building, staff, equipment, and business operations. That’s why professional exhaust duct cleaning is not only recommended—it is required by NFPA 96 fire code.
At Aurora Kitchen Hood Cleaning, we offer comprehensive Exhaust Duct Cleaning services designed to eliminate grease accumulation, restore proper ventilation, and ensure full compliance with national fire-safety standards. Our team uses specialized equipment and industry-approved methods to clean every accessible inch of ductwork, from the hood to the exhaust fan, leaving your system safe, efficient, and inspection-ready.
⭐ Why Exhaust Duct Cleaning Is Essential
Grease accumulation inside exhaust ducts is not something you can simply wipe away or treat with surface cleaning. The deposits inside these ducts are often thick, hardened, and layered. Over time, this buildup:
Increases fire hazards
Restricts airflow, forcing fans to work harder
Allows smoke and odors to linger
Leads to overheating of the exhaust fan motor
Reduces energy efficiency
Violates NFPA 96 compliance requirements
Fire safety organizations, insurance providers, and local health departments all require regular exhaust duct cleaning, and failing to maintain the system can result in fines, increased liability, or even temporary closure of a commercial kitchen.
Proper duct cleaning is crucial for maintaining a safe, healthy work environment and protecting your business from preventable hazards.
⭐ Our Exhaust Duct Cleaning Process
Our cleaning process is designed to ensure that every section of your ductwork—whether horizontal, vertical, long-run, or multi-level—is thoroughly cleaned. We go beyond the surface to deliver a true top-to-bottom, end-to-end cleaning.
✔ Inspection & Access Point Identification
We begin by inspecting your entire exhaust system to locate access points, evaluate the type of ductwork, and determine the level of grease accumulation. NFPA 96 requires specific types of access panels to be installed throughout the duct system, and we ensure these are properly used or recommend installation where needed.
✔ Accessing the Ductwork
Depending on your setup, we access the ducts through:
Existing openings
Baffle filter openings
Access panels
Fan housing
Rooftop or exterior entry points
This allows us to reach areas that are typically hidden and difficult to clean using traditional methods.
✔ Scraping & Mechanical Grease Removal
Before degreasing begins, we manually scrape away thick, hardened grease deposits inside the duct. This step removes the bulk of the buildup and exposes the remaining residue for deeper cleaning.
✔ Degreasing with NFPA-Approved Chemicals
Once the majority of grease is removed, we apply commercial-grade, fire-code–approved degreasers throughout the ducts. These break down stubborn residues that scraping alone cannot remove.
✔ Hot Water Rinse & Final Washdown
After the degreaser has done its job, we rinse the ducts with hot water to flush away loosened grease and restore clean metal surfaces. This step ensures all residue is removed, not simply pushed around.
✔ Fan to Hood Total System Cleaning
Our process covers the entire system:
The hood canopy
The plenum area
Vertical ducts
Horizontal ducts
Elbows and transitions
Fan housing and blades
Rooftop components
This ensures the system is cleaned completely—not partially.
✔ Final Inspection & Verification
We complete the service with a final inspection to ensure all grease has been removed and airflow has been restored. This includes checking the exhaust fan performance, airflow consistency, and general ventilation health.
