Choose a service below for full details, typical inclusions, and how we approach the work. Every option is built for restaurants and other commercial kitchens—not residential HVAC.
Commercial exhaust hoods
Professional cleaning of commercial kitchen exhaust hoods, plenums, and related grease-capture components for restaurants and foodservice kitchens.
Rooftop exhaust fans
Cleaning of commercial kitchen exhaust fans and housings so grease does not overload fan surfaces that move air out of the kitchen.
Commercial kitchen grease ducts
Cleaning of commercial kitchen grease ducts that carry exhaust from the hood toward the rooftop fan—not residential or generic HVAC duct cleaning.
Commercial grease filters
Cleaning of commercial kitchen grease filters that sit in the hood and help capture grease before it moves farther into the exhaust system.
Cleaning & documentation readiness
Exhaust cleaning and documentation support so commercial kitchens can present recent maintenance before a planned review—not an official inspection service.
