Exhaust systems pull grease, smoke, fumes and moisture out of your building. When they load up, they become a fire hazard, an odor source and a code problem. We clean the whole system to bare metal and document it — from commercial kitchens to industrial process exhaust.
A commercial kitchen exhaust system captures grease-laden vapor at the hood and carries it up through ductwork to a fan on the roof. Every foot of that path collects a flammable grease film. NFPA 96 — the national standard for commercial cooking ventilation — treats that buildup as a fire hazard and requires the entire system to be cleaned on a set schedule, from the hood to the fan to the rooftop discharge.
It is not only kitchens. Industrial process exhaust, laboratory and fume exhaust, parking-garage and general building exhaust all load with contaminants that degrade air quality, spread odor and reduce the airflow the system was designed to move. Left alone, exhaust fans lose capacity, grease drips onto roofs, and inspectors write violations.
IAQ Restoration cleans commercial and industrial exhaust systems to the measurable standard the code expects — hood, ductwork, fan and discharge cleaned to bare metal where required, with photo documentation and a dated service report your AHJ, insurer and health inspector will accept.
Grease buildup in kitchen exhaust is a leading cause of restaurant fires. NFPA 96 makes cleaning mandatory — and makes the building owner and operator responsible for it. A documented cleaning is your proof.
From the capture point to the rooftop discharge — every part of the exhaust path, cleaned and documented.
Hoods and capture areas are degreased to bare metal, including the plenum behind the baffles where grease hides.
Baffle filters are removed, cleaned or replaced so they capture grease instead of passing it into the duct.
The full duct run and vertical risers are scraped and cleaned to bare metal — the section most cleaners skip.
Rooftop and inline exhaust fans are cleaned, hinged back safely, and returned to full airflow.
Grease boxes and containment are serviced and the rooftop discharge area is cleaned to prevent drips and slips.
Process, lab, restroom and garage exhaust systems are cleaned to restore airflow and remove contaminants and odor.
Kitchen or industrial, one hood or a whole campus — cleaned to the right standard and documented.
A documented, code-aligned process from inspection to the dated service sticker.
We inspect the hood, duct run and fan, note access points and grease depth, and photograph the baseline.
Kitchen surfaces, equipment and floors are masked and contained so cleaning never contaminates the space below.
Hoods, plenums and baffle filters are scraped and washed to bare metal with hot water and degreasers.
The full duct run and vertical risers are cleaned to bare metal — hand-scraped where power methods cannot reach.
The exhaust fan is cleaned, its base and roof discharge degreased, and the fan returned to full airflow.
We apply a dated service sticker and hand you a photo-documented report for your AHJ, insurer and health inspector.
Cleaning grease out of the hood, duct and fan removes the fuel that turns a flare-up into a structure fire — and satisfies NFPA 96.
A clean exhaust system pulls smoke, grease, heat and odor out the way it was designed to, instead of pushing it back into the space.
A dated sticker and photo report give your health inspector, fire marshal and insurer exactly the proof they require.
Two or more of these and the system is a hazard, not just dirty.
Exhaust, supply and equipment all work together. Explore the connected services — or the commercial air duct cleaning pillar.
NFPA 96 sets frequency by cooking volume: monthly for solid-fuel and high-volume operations, quarterly for high-volume, semi-annually for moderate-volume, and annually for low-volume. We assess your operation and put you on the correct schedule, and clean the whole system — hood, duct and fan — each visit.
The full system. NFPA 96 requires the hood, the entire duct run and risers, and the exhaust fan to be cleaned to bare metal where accessible. Hood-only cleanings leave the most dangerous grease in the ductwork. We clean and photograph the entire path.
Yes. Every cleaning ends with a dated service sticker on the system and a photo-documented report showing before-and-after condition — exactly what your fire marshal, health inspector and insurance carrier require.
Yes. Alongside NFPA 96 kitchen work, we clean industrial and process exhaust, laboratory and fume exhaust, parking-garage CO exhaust, and general building and restroom exhaust — restoring airflow and removing contaminants. Call 800-883-6040.
