Kitchen Hood Cleaning Cost Guide: What Commercial Operators Should Budget
This is a commercial guide — restaurants, hospitals, campus kitchens, not residential range hoods. It explains what a complete NFPA 96 cleaning costs, what moves the quote, and how to compute your true annual number.

What Does Commercial Kitchen Hood Cleaning Cost?
Service-Tech Corporation's commercial kitchen exhaust hood cleaning starts from $599 per cleaning. That figure covers a professional cleaning of the exhaust system, performed by a crew that cleans the whole system — hood, filters, ductwork, and exhaust fan — not a wipe-down of the visible canopy.
Note the word commercial. Much of what ranks for this search is residential range-hood content from national aggregators, quoting numbers that have nothing to do with a restaurant, hospital, or cafeteria exhaust system. A commercial system is a fire-protection asset governed by NFPA 96, and it is priced by system anatomy, not by appliance.
Above the starting price, quotes scale with the system. Market pricing is commonly framed per hood, per hour, or per linear foot of duct. Service-Tech quotes per system after a free assessment, so multi-hood and multi-story systems are priced on what the work actually requires.
What Actually Moves a Hood Cleaning Quote
Two kitchens can both have "one hood" and receive very different quotes. The system behind the hood is what drives cost:
- Hood count and size. Each additional canopy adds filters, plenum area, and duct connections.
- Duct length and vertical runs. A single-story duct to a rooftop fan cleans faster than a multi-story vertical run through a high-rise or hospital, which may require scaffold-free rope or lift access.
- Fan accessibility. Rooftop fans with safe access clean quickly; fans on steep roofs, penthouses, or tight mechanical rooms take longer.
- Grease condition. A system on a regular schedule cleans predictably. A first-time or overdue cleaning with heavy, hardened grease can take multiples of the time.
- Access panels. Systems without adequate duct access panels require panel installation before the duct interior can actually be cleaned to bare metal.
- Service window. Overnight and weekend windows around continuous food service shape crew scheduling.
Your Real Number Is Annual: Frequency × Cost per Cleaning
No ranking cost page computes the number that matters to an operator: the annual budget. NFPA 96 sets cleaning frequency by cooking volume — systems serving solid-fuel cooking are on the most frequent schedule (commonly monthly), high-volume operations quarterly, moderate-volume semiannually, and low-volume annually (verify your classification against the NFPA 96 edition your local fire authority enforces). Your annual budget is your per-cleaning cost multiplied by that mandated frequency:
| Cooking volume (NFPA 96 class) | Typical venues | Cleanings per year | Annual budget |
|---|---|---|---|
| Solid fuel | Wood-fired pizza, charbroil, smokehouse | ~12 | 12 × per-cleaning cost |
| High volume | Extended-hours diners, wok, heavy fry lines | 4 | 4 × per-cleaning cost |
| Moderate volume | Standard full-service restaurants | 2 | 2 × per-cleaning cost |
| Low volume | Churches, seasonal kitchens, senior centers | 1 | 1 × per-cleaning cost |
With Service-Tech's from-$599 starting point, a moderate-volume kitchen's baseline is easy to sanity-check — and a quote dramatically below that across a full system should prompt scope questions, not celebration.
What a Complete Cleaning Includes — And What Cheap Quotes Omit
The grease that burns in an exhaust fire is rarely in the hood you can see; it is in the duct and fan you can't. A lowball quote usually pays for the visible part only. Before comparing prices, confirm every bid covers:
- 01
Hood, filters, and plenum
degreased to bare metal, filters cleaned or swapped.
- 02
The full duct run
horizontal and vertical, through every access panel, to bare metal per NFPA 96.
- 03
The exhaust fan
blades, housing, and grease containment at the roof, the most commonly skipped item.
- 04
Documentation
service sticker, before/after photos, and a written report identifying any inaccessible areas, which is what your fire inspector and insurance carrier actually look for.
Skipping items 2-4 doesn't save money; it converts a cleaning invoice into a deficiency finding — or a fire exposure. Industry and NFPA fire-loss reporting consistently ties commercial kitchen fires to grease accumulation in unclean exhaust systems, and after a grease fire, the service documentation trail is among the first things reviewed.
Ohio and Florida Market Context
National aggregator averages flatten real regional differences. In Service-Tech's home markets: Northeast Ohio winters push fan work into tighter safe-access windows and reward contractors with local crews rather than traveling franchise teams, while Florida's year-round operation and humidity keep grease systems loading continuously. Service-Tech has cleaned commercial kitchen systems from Cleveland since 1960 with IKECA-member crews, and serves Florida from its Tampa-area office. Enforcement posture also varies by local fire authority — budget to your inspector's expectations, not a national average.

Which Steps Actually Consume the Hours
Hood cleaning is priced by the difficulty of reaching bare metal, not by hood width.
- Gauge first. A comb-gauge reading of grease depth tells you whether this is a scheduled clean or a remediation, and the two are different jobs at different prices.
- Scrape before chemistry. A heavily loaded system needs mechanical scraping before any degreaser will work. That is the step cut-rate operators skip, and it is most of the labour on a neglected system.
- The full path, not the visible part. Hood interior, filters and baffles, the whole duct run, the fan housing and blades, and the rooftop termination. A quote that prices only what a customer can see is pricing a fraction of the standard.
- Access. A duct run with no access panels cannot be cleaned. Fitting compliant doors is fabrication work priced separately, and it is a one-time cost that makes every future clean cheaper.
- Containment and clean-up. Hot-washing means water and dissolved grease that has to be captured, squeegeed to containment and removed — inside someone's kitchen, usually overnight.
- Roof protection. Grease containment at the fan is a small line item that prevents a membrane repair, which is not.
Frequently Asked Questions
How Much Does Commercial Hood Cleaning Cost per Hood?
Per-hood pricing is common in the market but can mislead: the hood is the least labor-intensive part of the system to clean. Service-Tech prices per system, starting from $599 per cleaning, so the duct run and exhaust fan — where the real fire load lives — are always in scope. A free assessment sets the firm number.
How Often Am I Required to Have My Hood System Cleaned?
NFPA 96 sets frequency by cooking volume: solid-fuel operations most frequently, high-volume quarterly, moderate-volume semiannually, and low-volume annually. Your local fire authority determines which edition applies and can require inspections that reclassify your kitchen. Multiply that frequency by your per-cleaning cost to get your true annual budget.
Why Is a First-Time or Overdue Cleaning More Expensive?
Hardened, accumulated grease takes far longer to remove to bare metal than the light loading found on a maintained schedule, and overdue systems often need access panels installed before the duct can be cleaned at all. Once a system is on schedule, per-cleaning cost typically stabilizes.
What Should Be on the Report After a Hood Cleaning?
A service sticker on the hood, before-and-after photo documentation, and a written report noting any areas that could not be accessed. That paper trail is what fire inspectors and insurance carriers request. If a contractor doesn't provide documentation, the cleaning may not count when it matters.
What If I Just Take the Lowest Quote?
Confirm the quote covers the full duct run and the exhaust fan to bare metal, includes documentation, and is based on your actual system rather than a phone estimate. A cheap cleaning that skips the vertical duct leaves the fire hazard in place — and leaves you paying twice when an inspection or insurance audit flags it.
