AHU cleaning in Oakwood
We clean air handling units for buildings in Oakwood and across Greater London, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. The work covers supply and extract fans, dampers and louvres and internal panels, and common reasons people get in touch are stale or musty smells from the ventilation and dust built up on fan impellers.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Oakwood, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Oakwood: your questions answered
Can you clean school ventilation in Oakwood during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 34 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Oakwood. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can you work in Oakwood outside opening hours?
Yes, nights and weekends are routine for us. It means the site in Oakwood keeps running as normal. Your opening times are the first thing we ask for.
Are you insured?
Yes. Full insurance covers our work, and we have been trading since 2009.
How long does it take to clean an air handling unit?
The work takes a single shift for a typical unit, longer for large or heavily soiled ones. Bigger units can be phased, and you can phone us on 0345 646 2711, or send details by email to plan it.
What should I send you?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.
Is there a report after cleaning?
Yes. You get a TR19® certificate plus before and after pictures. They’re worth keeping with the plant records.
Can you clean the ducts connected to the AHU?
Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can quote for both.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
How we price AHU cleaning
The quote reflects the site in front of us. We take into account:
- Any permits to work or inductions
- How big the system is
- The condition of the system
- The times the site is available
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.
Helping us quote
There’s no need for technical detail. It helps if you can send:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Close-ups of filters, grilles, hatches or access panels
- When the site is open and when it’s quiet
- Any previous report or certificate
For AHU cleaning in Oakwood, call 0345 646 2711 or email us. Let us know the site type and the opening hours, plus photos or the previous report if they’re to hand. A fixed quote usually follows within one working day.
What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Ventilation in Oakwood buildings
Food Standards Agency data includes about 34 schools, colleges and universities and about 38 care, childcare and hospital premises in Oakwood and the streets around it, up to about 1.5 miles out. Busy, occupied buildings like these are where clean supply air matters most. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first. Chase Farm Hospital is the nearest hospital, about 1.9 miles north-east of Oakwood. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
If you manage a school such as Wolfson Hillel Primary School, ventilation cleaning is best booked for the holidays.

Signs you need AHU cleaning in Oakwood
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
These are the problems we see most often:
- Dirty coils holding back the airflow
- Leaves and litter drawn into the unit
- Air handling units never cleaned inside
- Air handling units due a clean after building work
Healthcare ventilation, from large hospitals like Chase Farm Hospital (about 1.9 miles north-east) to small clinics, depends on clean filters, coils and ducts.

What a clean won’t put right
We will not sell you work that doesn’t address the problem, so here are the limits:
- Problems with the unit’s controls or sensors
- Ventilation that was badly designed in the first place
- Coils that are corroded or leaking and need replacing
Not sure which it is? You can call 0345 646 2711, or send details by email and we will tell you honestly before you book.

Aftercare tips
So the system stays in good health:
- Plan the next inspection before the last report gets filed away
- Keep inspection doors on the unit in good order
- Store the TR19 paperwork where auditors can find it
- Clear leaves and litter away from the intake
We recommend when the unit should next be inspected or cleaned, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
The process
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes anything from half a day for one small unit to several shifts for a plant room full of them. In Oakwood, as across London, we usually work overnight or at weekends and hand the site back ready to open.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Getting ready for the visit
- Have your last certificate or report to hand
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Name a contact who can let us in at the agreed time

Part by part
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with pictures so repairs can be planned.
Filters
Filters are the first line of defence in the unit. As part of the clean, filters are checked and cleaned or replaced as agreed, and the housing around them is cleaned too.
