Number of registers and runs
The count of supply and return points and how the ducting runs decide the work far more than floor area does. We note them at the inspection.
Air Duct Cleaning Company for commercial systems
Ductwork collects what the air carries: dust, lint and, where there's moisture, mould. It builds inside the ducts where you can't see it, then blows back into the space every time the system runs. Vacuuming a grille doesn't reach it. Putting the whole system under negative pressure and agitating the ducts does.
- A full crew for the whole system
- Scope and rate agreed first
- Negative-air containment
- Registers, ducts and coils
When a duct system needs cleaning
The smell and the dust are the late signs, not the first. If one of these fits, it's time.
-
Dust blows out when the system starts
A puff of dust from the vents when the AC kicks in means the ducts are holding it. What's inside the duct is being pushed into the room every cycle.
-
Grey staining around the grilles
Dark marks fanning out from the registers are dust that the airflow has driven onto the ceiling. It shows the duct behind them is loaded.
-
A musty smell when the AC runs
A damp, stale smell only when the system is on points to moisture and growth inside the ducts or on the coil. Air freshener covers it; it doesn't clear it.
-
Dust resettles fast after cleaning
If surfaces go dusty again within days of a thorough clean, the system is putting it back. The room can't stay clean while the ducts are dirty.
-
Allergy or stuffiness complaints in the space
Staff or visitors reacting more indoors than out is often the air. Ducts hold dust and allergens and recirculate them through the space.
-
No record of the last duct clean
If nobody can say when the ducts were last done, it has been a while. A new fit-out, a change of tenant or a health inspection is the usual reason to book.
What the service includes, and what it does not
The second list is the one that prevents disputes, it is usually in small print, or not written at all.
-
Duct inspection before we start
We check the system layout and look inside the ducts, so we know the buildup before the work is agreed.
-
Grilles and vents removed and washed
Vent covers and grilles come off and are washed separately, since they are where visible dust settles first.
-
Ducts cleaned from the inside
Suction and forced air inside the ductwork pull out packed dust that no amount of outside cleaning will reach.
-
Coils we can reach
The coils reachable without dismantling the unit are cleaned, because that is where moisture and dust collect together.
-
Odour treatment and sanitising
A treatment that cuts odour and mould inside the ducts, applied after the dust is out rather than before.
-
Filter housing cleaned
The box the filter sits in collects dust of its own, and we fit your replacement filter if you have one.
Not included
- Mechanical or refrigerant repair to the unit
- Ductwork replacement, resealing or modification
- Cleaning inside sealed rooftop units beyond the access panels
- Handling asbestos or hazardous insulation
If the inspection shows a repair, a sealing problem or hazardous insulation, we tell you rather than clean over it. Where a licensed trade is needed, we point you to the right one even when it isn't our work.
How duct cleaning actually runs
The order is what makes it work. Agitate before the system is sealed and you spread the dust into the room. This is the sequence.
-
1
Inspect and map the system
We look inside the ducts and at the coil, note the buildup and the access points, and agree the scope and rate before starting.
-
2
Protect the space and seal registers
Registers not being worked are sealed and the area protected, so dislodged dust has one path, into the vacuum, not the room.
-
3
Put the system under negative pressure
The vacuum holds the whole run under negative pressure first. Only then is anything disturbed, so what comes loose is pulled out, not blown around.
-
4
Agitate and dislodge the ducts
Brushes and compressed air work the duct walls to release dust and lint that suction alone won't lift, while the negative pressure collects it.
-
5
Clean registers, coils and diffusers
Grilles are washed, and the coil and diffusers reached through access panels are cleaned, since a dirty coil re-loads the ducts.
-
6
Inspect after and walk it with you
We check inside the ducts again and walk the result with your contact before leaving. Anything not right is redone on the same visit.
What decides the price
We do not publish a fixed figure, because cases genuinely differ. These are the factors we ask about, so you know where your job sits before you call.
System type and access
Ducted splits, packaged units and central systems differ in how they're reached. Access panels and their placement decide what can be cleaned and how.
Level of buildup or contamination
A system cleaned on a cycle is quicker than one that hasn't been touched in a long time. Where there's moisture or growth, the coil needs more attention, and we say so first.
Whether the space stays in use
Cleaning around occupancy or out of hours changes how the work is scheduled. An empty space is a different job from a working one.
Add-ons on the same visit
A wider facility clean done in the same visit costs less than a separate trip, because access and setup are counted once.
Send the number of vents, the system type and a few photos on WhatsApp, and you get an estimated rate and duration before you commit.
Vacuum the grille, or clean the system?
A shop vac at the grille clears what you can see. The dust that gets recirculated is further in, and that's the difference.

Why us for this work specifically
A full crew arrives together
We send a crew, so a whole system is done in one scheduled visit instead of being split across days while it keeps recirculating dust.
Negative-air containment
The system is held under negative pressure before anything is disturbed, so dislodged dust is collected rather than blown into your space.
We inspect after, not just before
We look inside the ducts again at the end and walk it with you, so the result is checked rather than assumed.
We say no when it's no
If the inspection shows a repair or a sealing problem rather than a cleaning one, we tell you. A clean over a fault helps nobody.
Our work
Photographs from real jobs carried out by the crew.
The job doesn't close before you sign off
The commitment is simple enough to keep: we don't leave before your contact has seen the result and said what they think.
- A post-clean inspection and walkthrough before the crew leaves
- Anything not right is redone on the same visit, with no new invoice
- The agreed rate is what's paid, any addition is priced before it's done
- If the inspection turns up a repair, we tell you rather than clean over it
Three written commitments
You know the price before we start
We look at the job and agree the figure before any work begins, and nothing is added to it afterwards. If the scope changes during the visit we stop and ask you before carrying on.
A handover walk before we leave
At the end of the visit we walk the place with you. Anything you point at is redone in the same visit, not booked for another one, and at no extra cost.
We keep the time, and tell you if we cannot
We arrive when we said we would. If that becomes impossible you hear it before the appointment rather than after, because waiting without knowing how long is worse than a delay you were told about.
Questions before you book
Will duct cleaning stop the dust in the space?
It removes a big source of it. Ducts hold dust and blow it back every cycle, so cleaning them and the coil cuts what keeps resettling. It won't stop dust that comes from the space itself, open doors, foot traffic, an old filter, which is why we check the filter too.
Do you clean the coil as well as the ducts?
The coil and diffusers reached through the access panels, yes, because a dirty coil re-loads clean ducts and is often where a musty smell starts. Anything sealed inside the unit that needs it opened for servicing is a mechanical job for a licensed trade, not part of the clean.
Can you clean the ducts while the space is occupied?
Often, out of hours or zone by zone, since the system is sealed and held under negative pressure so dust is contained rather than blown into the room. We plan around your occupancy at the inspection so the space keeps running.
Do you repair the ductwork or the unit?
No. We clean. Duct replacement, resealing and refrigerant or mechanical repair are separate trades with their own licensing. If the inspection shows one is needed, we tell you and point you to the right specialist rather than clean over it.
Will duct cleaning leave dust or a smell in the space?
Because the system is under negative pressure and registers are sealed, the dislodged dust goes into the vacuum, not the room, so mess is kept down. If there was a musty smell from the coil, cleaning the source usually clears it rather than masking it.
How often should commercial ducts be cleaned?
It depends on the environment, not a fixed date, dust load, occupancy, humidity and whether there's been construction nearby all decide it. A clinic or a dusty industrial area needs it sooner than a quiet office. We can suggest a cycle after the inspection.
