Kitchen Hood Exhaust System


Consistent maintenance of the kitchen hood exhaust system in your restaurant or facility remains one of the primary defenses against fire hazards. Regularly performed, professional cleaning of the kitchen exhaust system has the following additional benefits:
• Minimized product contamination
• Improved health standards
• Enhanced public image
• Improved ventilation for smoke and odor removal
• Compliance with local and national fire and health codes
• Improved government ratings
• Increased energy savings
• Enhanced working environment for kitchen staff

Our established cleaning methods remove the grease and flammable residues from the interior surfaces of the hood, filters, duct work and exhaust fans ensuring compliance with all applicable municipal, state and NFPA codes. Upon completion of the cleaning process, a Proof of Performance decal is posted on the hood canopy in plain view of the Fire Marshall, Department of Health or Insurance Agent.

Our professional scope of work involves cleaning all components and ductwork in the kitchen exhaust system for proper maintenance and to prevent fires. Furthermore, by cleaning the entire system, we are able to check for possible system blockage, and visually verify that the louver and dampers are working properly.
