If you’ve been searching for a hood cleaning service for your restaurant, you’ve probably noticed the terms get used almost interchangeably – hood cleaning, exhaust hood cleaning, kitchen flue cleaners, commercial kitchen exhaust cleaning. Are they the same thing? Mostly, but not entirely – and knowing the difference will help you ask the right questions before you hire anyone to work on your kitchen.

At Fast Hood Cleaners, we get asked this almost every week by restaurant owners across Ontario. Here’s the breakdown, in plain language.

“Hood Cleaning” – The Visible Part of the System

When people search hood cleaning or kitchen hood cleaning, they usually mean cleaning the stainless steel canopy that hangs above the cooking line, plus the removable grease filters inside it. This is the part your staff and health inspector see every day, so it’s the first thing that gets noticed when it’s dirty – and the first thing customers picture when they think about “hood cleaning.”

But here’s the catch: a hood that looks spotless on the outside can still have heavy grease buildup hiding in the ductwork behind it. That’s why a proper job never stops at the visible canopy.

“Exhaust Hood Cleaning” – The Whole System, Hood to Roof

Exhaust hood cleaning and commercial kitchen exhaust cleaning refer to the full path grease vapor travels – canopy, plenum, ductwork, and the rooftop exhaust fan. This is the scope required under NFPA 96, and it’s the standard we follow on every job (we covered the required cleaning frequency in detail in our NFPA 96 compliance guide if you want the specifics on how often your kitchen needs service).

If a company quotes you for “hood cleaning” but only wipes the canopy and skips the ductwork and fan, you’re not getting a code-compliant clean — and you may not pass your next fire inspection.

“Kitchen Flue Cleaning” – Same Job, Different Word

This is where canadian kitchen flue cleaners comes in as a search term. “Flue” is simply another name for the duct or chimney-like shaft that carries grease-laden air out of the building – the same component covered under exhaust hood cleaning. So if you’ve been searching for a flue cleaner, you’re looking for the same certified duct-and-fan cleaning service, just under a different name. In Ontario, this work is governed by the same NFPA 96 standard, regardless of which term the company markets itself with.

Bottom line: hood cleaning, exhaust hood cleaning, and flue cleaning aren’t three separate services – they’re three names circling the same job. The real question isn’t which term to search for, it’s whether the company you hire cleans the entire system or just the part you can see.

What to Ask Before You Book a Hood Cleaning Service

Since the terminology is inconsistent industry-wide, the safest move is to ask direct questions before booking:

• Does the service include the ductwork and rooftop fan, or just the hood and filters? (It should include all of it.)
• Are your technicians certified? Ours are trained through MFS Trade School and follow NFPA 96 code standards on every job.
• Will I get before-and-after photos and a certificate? You’ll need this for your fire marshal, health inspector, and insurance file.
• Can you work around my kitchen’s hours? A good crew should schedule around your service times, not the other way around.
• Do you service my area? We cover the Greater Toronto Area and cities across Ontario – Toronto, Mississauga, Vaughan, Brampton, Hamilton, Barrie, Kingston, London, Windsor, and many more.

Why This Matters for Fire Safety and Compliance

We’ve written before about why regular exhaust hood cleaning is essential for fire safety – grease that builds up unnoticed in ductwork is one of the leading causes of commercial kitchen fires, and it’s exactly the part of the job that gets skipped when a company only cleans “the hood” instead of the full exhaust system.
