What is included in a hood cleaning service?
The hood-cleaning process typically includes degreasing and polishing the kitchen hood, cleaning the filters, and scraping or washing the ductwork and exhaust fan. It’s a comprehensive process where pros use food-safe chemicals and pressure washing to remove grease from the entire system, including everything from the cooktop to the rooftop fan. Always confirm what's included before hiring a pro, as specific services may differ.
What questions should I ask before hiring a hood cleaning pro?
Before hiring a cleaner for your hood, be sure to ask your pro these questions:
Are you licensed and insured to perform commercial kitchen exhaust cleaning?
Do you follow NFPA 96 standards, and will you provide a service report after the job is complete?
What does your cleaning process include? Does it cover the hood, ducts, filters, and the rooftop exhaust fan?
How do you protect kitchen equipment and surfaces during the cleaning process?
Can you provide references from other restaurants you’ve serviced in the area?
How long will the service take, and what do we need to do to prepare the kitchen beforehand?
How do you determine your pricing, and can you provide a detailed, itemized quote?
Do pros have to be certified to clean restaurant hoods?
While certification isn't a universal legal requirement, most local fire marshals and insurance providers do require it. Certified professionals are trained on NFPA 96 standards, which helps them ensure your kitchen's ventilation system is cleaned correctly and safely to prevent fire hazards.
How often should you clean a restaurant range hood?
Most restaurants need their range hoods cleaned quarterly, but the exact frequency depends on your cooking volume. High-volume operations using woks or charbroilers typically require quarterly service. Moderate-volume kitchens can often go six months between cleanings. If your restaurant's kitchen volume is low, you may only need to clean it once a year. Always check your local fire codes for specific requirements. An experienced pro should be able to provide guidance on the appropriate cleaning schedule.
What happens if you don't clean a restaurant's kitchen hood?
If you don’t clean a commercial kitchen hood, grease and debris can build up quickly, creating serious risks. For example:
Fire hazard: Grease accumulation in the hood and ductwork can ignite and spread rapidly.
Poor ventilation: Smoke and odors won’t vent properly, affecting air quality.
Equipment strain: Fans and motors work harder, leading to breakdowns.
Insurance issues: Claims may be denied if required cleanings aren’t documented.
Regular professional hood cleaning can help reduce fire risk and keep your kitchen compliant and safe.
What factors affect the cost of cleaning a restaurant hood?
There are several factors that might impact the cost of this service, including:
System size and type: The total number of hoods and the length of the ductwork are big factors. More complex systems, like those for solid-fuel cooking, can also require more work, therefore driving up the cost.
Grease buildup: A system with heavy grease accumulation will take more time and effort to clean than one that’s regularly maintained, which can affect the price.
Accessibility: If your exhaust fan or ductwork is hard to reach (for example, on a high or pitched roof), the pro may need extra time and equipment.
Cleaning frequency: You might get a better rate for setting up a recurring cleaning schedule, like quarterly or semi-annually, versus a single, one-off cleaning.
Additional services: The cost can also change if you need extra services like replacing filters, checking fan belts, or cleaning the rooftop around the fan.
