Compliance requirements
NFPA 96 requires hood cleaning frequency based on cooking volume: monthly for high-volume operations, quarterly for moderate, and semi-annually for low-volume. LA County Environmental Health inspectors cite dirty hoods as a top violation.
Required frequency: Every 3 months (quarterly), per NFPA 96 — more frequently for high-volume or solid-fuel operations.
Boh tracks your compliance schedule and reminds you before your next window.
Why Boh, not a standalone vendor
Every job is dispatched to a specialist in our vetted network. Here's why that's better for you than managing vendors yourself.
Specialists, not generalists
Vendors in our network focus on a single service type. They're faster, more thorough, and more familiar with compliance requirements than any multi-service in-house team could be.
Every job is documented and reviewed
Before and after photos, service reports, and compliance tags are required on every visit. Vendors know each job is tracked and reviewed by Boh. That visibility keeps quality high.
Underperformance has consequences
If a vendor misses a visit, cuts corners, or fails to document properly, they're removed from the network. You never have to manage that conversation. Boh holds them accountable so you don't have to.
Broader coverage, more availability
A network of specialists covers more neighborhoods, more service windows, and more kitchen types than any single in-house team - meaning faster response and more scheduling flexibility for your operation.
Local conditions that affect this service
Environmental factors in Southern California cities can significantly change how often this service is needed - and what happens if you skip it.
Elevated AQI adds external particulate to hood buildup
Worth notingIn high-AQI cities, airborne particulate matter drawn through kitchen exhaust systems mixes with cooking grease in hood ducts and filters - accelerating buildup beyond what cooking volume alone would produce. This can push kitchens past their compliance cleaning interval faster than operators expect, particularly during wildfire smoke events.

Issues this service resolves
Grease Fire in the Duct or Hood
A grease fire in your exhaust duct is a serious safety event. The kitchen must be inspected and the duct system professionally cleaned before you can reopen.
→ See how we help
routineHood Fan Making Noise or Vibrating
Rattling, banging, or vibrating from your exhaust hood fan often points to a worn belt, failing motor bearing, or debris caught in the fan assembly.
→ See how we help
routineStrange Smell Coming From the Hood
Burning, rancid, or chemical smells from the exhaust hood usually mean accumulated grease is overheating, or that mold and bacteria have built up inside the duct system.
→ See how we help
routineHood Cleaning Tag Expired or Missing
LA County and NFPA 96 require a dated service tag on every hood after each cleaning. A missing or expired tag is a compliance violation and can trigger a re-inspection.

urgentKitchen Filling With Smoke During Service
Smoke backing up into the kitchen during cooking usually means your exhaust hood is no longer pulling air effectively — often due to grease buildup blocking airflow.
→ See how we help
urgentHood Not Draining Grease Properly
Grease pooling in the hood or dripping onto equipment means your hood's drainage channels are blocked — a sign the system is overdue for cleaning.
→ See how we help
urgentHood Not Pulling Air / Weak Suction
A hood that isn't drawing smoke and fumes away from the line is a ventilation and compliance issue. Grease-blocked filters or ducts are the most common cause.

urgentCited for Grease Buildup at Health Inspection
LA County health inspectors cite restaurants for visible grease accumulation on hood surfaces, filters, and ducts. This requires documented professional cleaning to clear.
