Is duct cleaning different from hood cleaning?
Yes. Hood cleaning focuses on the canopy and plenum area, while duct cleaning addresses the horizontal and vertical pathways that move grease-laden air toward the fan.
Exhaust Duct Cleaning
R & G removes grease deposits from accessible horizontal and vertical ductwork between the hood and rooftop fan for commercial kitchens across Phoenix Metro and Maricopa County.

Grease-laden vapor moves from the cook line through the hood, plenum, ductwork, and fan. Because ducts are often hidden, surface-only hood cleaning can leave a significant portion of the exhaust system untreated. Duct cleaning supports a complete hood-to-roof maintenance program.
Proper access panels allow technicians to inspect and clean areas that cannot be reached from the hood or roof opening. The agreed scope should identify accessible horizontal ducts, vertical risers, elbows, transitions, access panels, and connections to the rooftop fan.
R & G documents inaccessible areas, damaged components, and observed maintenance concerns for the facility operator. For overdue buildup, an inspection concern, or a time-sensitive reopening, call to confirm emergency hood cleaning availability.
Restaurants, cafeterias, ghost kitchens, schools, hospitals, hotels, churches, correctional facilities, and production kitchens across Maricopa County. Residential duct or range hood cleaning is not available.
