Kitchen Hood Fire Suppression Systems

Commercial kitchens are the highest fire-risk occupancy most cities have, and codes treat them that way: NFPA 96 requires the wet-chemical suppression system protecting your hood, ducts, and cooking appliances to be inspected and serviced every six months by a qualified company. Our directory connects restaurants, cafeterias, and commissaries with licensed hood suppression contractors.

Semiannual service isn't optional — an out-of-date system tag can shut down your kitchen during a health or fire inspection, void your insurance in a fire, and put your staff at risk. Modern systems must also meet the UL 300 standard; if your kitchen still runs an older dry-chemical system, insurers and AHJs increasingly require an upgrade.

Semiannual service typically runs $150–$400 per system depending on size and link count. New UL 300 system installations generally range from $3,000 to $7,000+ depending on hood length and appliance coverage.

No. Hood and duct cleaning (grease removal) and suppression system service are separate NFPA 96 requirements performed by different specialists. You need both, each on its own schedule.
