Commercial kitchen exhaust hoods serve three functions: ventilation, grease capture, and fire suppression linkage. A failed exhaust hood fan creates an immediately unsafe kitchen environment — heat, smoke, and grease vapor accumulate rapidly. We treat commercial hood calls as priority service.
LAFD regulations require commercial exhaust hood systems to be maintained and cleaned at regular intervals based on cooking volume. We inspect grease duct condition on every exhaust hood service call and advise on cleaning compliance. A hood that passes the electrical test but has a grease-clogged duct is still a fire hazard.
