Exhaust, Hood & Complete Ventilation System Cleaning By Kitchen Guard of Phoenix
Kitchen exhaust cleaning in Phoenix has to keep pace with kitchens that run hot year-round. Grease builds faster here than most operators expect. Kitchen Guard of Phoenix cleans the entire exhaust system, not just the visible stainless. That means hood plenums, filters, grease troughs, horizontal and vertical duct runs, access panels, and the rooftop exhaust fan. Anything less leaves fuel in the system and leaves you exposed on your next fire inspection.
What NFPA 96 Actually Requires, and How Often
NFPA 96 is the national standard for commercial kitchen ventilation. Your fire inspector and your insurance carrier both work from it. It does not set one date for everyone. It sets frequency by what and how much you cook:
- Monthly — systems serving solid-fuel cooking operations such as wood, charcoal or mesquite.
- Quarterly — high-volume operations, including 24-hour kitchens, charbroiling and wok cooking.
- Semi-annually — moderate-volume operations, which covers most sit-down restaurants.
- Annually — low-volume operations such as churches, seasonal businesses and senior centers.
Not sure which tier you fall into? Our frequency chart by restaurant type walks through it, or call (602) 536-4663 and we will tell you in about two minutes.
What a Kitchen Guard Cleaning Includes
Every visit follows the same documented sequence. The result holds whether it is your first clean or your thirtieth:
- Walk the kitchen and the roof, confirm hood type and access points, and flag anything that needs repair before we start.
- Mask and protect cooklines, floors and equipment with plastic sheeting and drop cloths.
- Remove and clean the baffle filters — or swap them out if you are on our filter exchange program.
- Hand-scrape heavy grease deposits from the plenum and grease trough.
- Pressure-wash the hood interior, plenum and accessible ductwork with hot water and commercial degreaser.
- Open access panels and clean the horizontal and vertical duct runs to bare metal wherever access allows.
- Clean the rooftop exhaust fan — housing, blades and hinge — and check the belt and rooftop grease containment.
- Polish the hood exterior, reinstall filters and panels, and clean up so the kitchen is ready for service.
- Photograph the finished work and leave documentation you can hand an inspector.
Where access is limited by the original installation, we note it in writing rather than quietly skipping it. NFPA 96 requires that any area not cleaned be documented, and that note is what protects you if a claim is ever filed.
One Price on Your Hood Cleaning, No Add-Ons
Rooftop cleaning is part of every visit, including the hard-to-reach areas around the fan curb — it is not billed as an extra. There is no heavy-buildup surcharge if your system has been neglected, no minimum charge, and nothing added to the invoice after the fact. The number we give you after the inspection is the number you pay.
Rooftop grease containment systems are a separate product rather than a hidden fee. If grease is escaping your fan and damaging the roof, we install and service them. The inspection will tell you whether you need one.
Recurring filter exchange is also its own service with its own pricing, so it is quoted separately rather than folded into your cleaning.
Documentation That Holds Up in an Inspection
You get before-and-after photos of every service. You also get a written report covering what was cleaned and anything that was not accessible. A dated service label on the hood itself — which is the first thing a fire inspector looks for. If your fire marshal or your insurer asks for cleaning history, you should not have to go hunting for it.
Kitchens We Clean Across the Valley
Restaurants and bars, hotel and resort kitchens, hospital and senior-living kitchens, school and university dining, corporate cafeterias, grocery prepared-foods departments, food trucks and commissary kitchens, breweries and taprooms, casinos, and quick-service chains. Pizza hoods, up-blast rooftop fans and multi-hood cooklines are routine work for us, not exceptions.
Kitchen Exhaust Cleaning Across the Phoenix Metro
Phoenix, Scottsdale, Tempe, Mesa, Chandler, Gilbert, Glendale, Peoria, Surprise, Goodyear, Avondale, Paradise Valley, Fountain Hills, Cave Creek, Queen Creek, Sun City, Anthem, Laveen and Ahwatukee. Our shop is at 2739 W Palm Ln in central Phoenix, just off I-17, which is how we get a truck to most Valley kitchens quickly.
Cleaning Around Your Service Hours
Most of our work happens after close or before open, because the only way to clean a system properly is with the cooking equipment cold. Tell us your hours and we will schedule around them.
A Free On-Site Inspection, Not a Phone Estimate
We will not price your kitchen over the phone. Hood count and cooking type tell us something, but they do not tell us how much grease is sitting inside a horizontal duct run or pooled around the fan curb on your roof, and those are the places that fail inspections. If grease has already made it onto the membrane, that becomes a rooftop containment question as well as a cleaning one. So we come out and look at all of it first. The inspection is free, it takes one visit, and the price we hand you afterward is firm.
Kitchen Guard of Phoenix is commercial only: restaurants and bars, hotels and resorts, schools, hospitals, senior living and institutional kitchens. Our technicians are trained in house to NFPA 96 guidelines, and they are W2 employees rather than subcontracted day labor, so the crew in your kitchen works the same way on every visit. We are locally owned and operated, backed by a brand that has specialized in commercial kitchen exhaust since 2009.
Grease does not stop at the hood. If it is showing up on your dumpster pad, your drive-thru or the walk out front, that is the same system telling you where it is going. See commercial pressure washing in Phoenix, which we can run on the same overnight visit.
Kitchen Guard of Phoenix Answers All Your Hood Cleaning Questions
Here are answers to some of the most common questions about our hood cleaning services, designed to keep your kitchen safe, compliant, and running smoothly.
Almost always yes. NFPA 96 applies to any kitchen with a Type 1 commercial hood, the kind installed over equipment that produces grease or smoke. If grease-laden vapor passes through your hood, the fire code applies regardless of how little you think you cook, and both your fire inspector and your insurance carrier will ask for proof of service. The good news is that low-volume kitchens fall into the annual tier, which is the least expensive interval we offer.
It depends on what and how much you cook, not on the calendar. NFPA 96 sets four tiers: monthly for solid-fuel cooking, quarterly for high-volume operations such as 24-hour kitchens, charbroiling and wok cooking, semi-annually for moderate-volume kitchens, and annually for low-volume operations. Most Valley sit-down restaurants land on a semi-annual or quarterly schedule. Tell us your menu and your hours and we’ll confirm the right tier for your kitchen.
NFPA 96 is the national standard for commercial kitchen ventilation and fire prevention, and local fire codes point to it. In the City of Phoenix, the Phoenix Fire Department enforces the Phoenix Fire Code, where kitchen exhaust is its own inspection category. Scottsdale, Tempe, Mesa, Chandler, Gilbert, Glendale and Peoria each have their own fire department acting as the authority having jurisdiction, so the details vary from city to city. Maricopa County Environmental Services handles the food-safety side of your permit separately. Practically speaking, NFPA 96 determines your cleaning frequency, what has to be cleaned, and what has to be documented — and it’s what your insurance carrier will reference if you ever file a grease-fire claim.
The whole system, not just the part you can see: the hood interior and exterior, the baffle filters, the grease trough, the plenum, the horizontal and vertical duct runs, the access panels, and the rooftop exhaust fan including housing, blades and hinge. Rooftop cleaning is part of every visit, including the hard-to-reach areas around the fan curb, and we check the fan belt and grease containment while we’re up there. A cleaning that stops at the hood leaves behind the grease that matters most, because duct and fan buildup is how a fire spreads from the cookline into the building.
No. Rooftop cleaning is included at every visit rather than billed as an add-on. There is no heavy-buildup surcharge if your system has gone a year or more without service, no minimum charge, and nothing added to the invoice after the fact. The price we give you after the free inspection is the price you pay for the cleaning. Rooftop grease containment systems and recurring filter exchange are separate services, quoted on their own rather than folded into the cleaning.
Most single-hood kitchens take about four hours. Larger cooklines with multiple hoods, long duct runs or heavy buildup take longer, and a system that has gone a year or more without service usually needs the most time on the first visit. We’ll give you a realistic window when we quote the job so you can plan around it.
You almost never lose a shift. Most of our work happens overnight or before open, because the equipment has to be cold and the kitchen empty for the system to be cleaned properly. Daytime service does work for some operations: a closed day, a pre-opening cleaning on a new build, or a school, church or corporate cafeteria that doesn’t run dinner. Tell us your hours and we’ll fit the visit around them.
Before-and-after photographs of every service, a written report covering what was cleaned and the date it was done, and a dated service label affixed to the hood — which is usually the first thing a fire inspector looks for. That package is what a fire marshal, a health inspector, an insurance carrier or a franchisor will ask to see. Keep it with your permit file, or ask us and we can resend your most recent report.
Some systems were built without enough access panels to reach every section of duct. When that happens we clean everything we can reach and document in writing exactly what was not accessible and why. NFPA 96 requires that disclosure, and it’s what protects you if there is ever a claim. We’ll also tell you what access panels could be added to solve it permanently.
Our technicians are trained in house to NFPA 96 guidelines, and they’re W2 employees rather than subcontracted day labor. That matters more than it sounds: it means the crew that shows up at your kitchen follows the same documented process every visit, and we’re accountable for their work rather than passing you to whoever was available that night.
Yes. If grease is escaping your exhaust fan and pooling on the roof, that’s a roof-damage and liability problem as much as a fire-code one, and landlords increasingly write it into leases. We install and service containment systems, and we’ll tell you during the free inspection whether yours needs one.
Yes. Food trucks, commissary kitchens, concession stands, cafes with pizza or panini hoods, and single-hood quick-service kitchens are all regular work for us. A smaller system still falls under NFPA 96, and it still needs documentation. We are commercial only, though — we don’t service residential range hoods.
Yes, and it’s a common switch. Tell us your current frequency and we’ll match or improve it, put your next several visits on the calendar, and pick up the documentation trail from there. If you’re not sure when your last cleaning was, we can usually tell from the condition of the system on the first visit.
Hood cleaning is the full system service on an NFPA 96 schedule, covering the hood, duct and rooftop fan. A filter exchange swaps your dirty baffle filters for clean ones on a more frequent cycle between deep cleans, which keeps grease from migrating into the ductwork in the first place. Many Valley kitchens run both together.
Yes. Because we’re on your roof and inside your system every visit, we tend to catch failing belts, worn bearings, damaged hinges and airflow problems before they shut you down. We handle exhaust system repairs alongside the cleaning schedule.
Call (602) 536-4663 or use the form on this page and we’ll set up a free on-site inspection. We don’t quote hood cleaning over the phone, because the grease that matters is in the places nobody can describe on a call — inside horizontal duct runs, behind access panels, and up on the roof around the fan. We look at all of it, then give you a firm price. If your system is overdue or you have an inspection coming, say so and we’ll prioritize the visit.
