A professional kitchen exhaust cleaning typically includes the hood canopy, grease filters, plenum, accessible ductwork, and the rooftop exhaust fan. The goal is to remove grease throughout the entire exhaust system, not just the visible hood.

Grease naturally builds up inside commercial kitchen exhaust systems over time. Regular cleaning helps improve ventilation, reduce grease accumulation, support fire safety, and keep your kitchen operating efficiently.

NFPA 96 is the industry standard that provides guidelines for the inspection, maintenance, and cleaning of commercial kitchen exhaust systems. Many businesses use these recommendations to help determine appropriate cleaning intervals.

Many exhaust cleaning services are scheduled after business hours or during slower periods to minimize disruptions. The schedule depends on your kitchen’s operating hours and cleaning needs.

Yes. The rooftop exhaust fan is an important part of the kitchen exhaust system and is included as part of a complete exhaust cleaning whenever applicable.

No. Much of the grease accumulates inside the plenum, ductwork, and rooftop exhaust fan where it can’t be seen during normal operations. A professional cleaning focuses on the entire exhaust system, not just the visible hood.

Excessive grease can restrict airflow, reduce ventilation efficiency, and increase the amount of combustible material inside the exhaust system. Regular professional cleaning helps remove this buildup before it becomes a larger problem.
