How we handle AHU cleaning in Wooburn Green
Where a building in Wooburn Green has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. Typical jobs include blocked condensate drains and slimy trays and dust-coated heating and cooling coils, on drain trays, filter sections and heating and cooling coils.
Around a place like Wooburn Green, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

In-house cleaning or a specialist?
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
What we do, step by step
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes anything from half a day for one small unit to several shifts for a plant room full of them, and the area is cleaned down before we leave. A site near Wooburn Green normally has room to park, so the questions are about access to the system and your hours.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Let us know about permits to work or site inductions
- Allow time for equipment near the work to be turned off and cool down

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before any work starts.

How much does AHU cleaning cost?

Do you give a certificate after the clean?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
Can you price the work without visiting?
Yes, where the photos show enough. If not, a site survey comes first, then a fixed quote.

We will not sell you work that doesn’t address the problem, so these are the things it won’t cover:
- Breakdowns that need a mechanical engineer
- Damaged coils beyond cleaning
- Ventilation that was badly designed in the first place
Not sure which it is? You can ring 0345 646 2711 or use the quote form and we’ll tell you honestly.

Keeping the system healthy
To keep the system working properly between visits:
- Do not ignore odours coming through the grilles
- Check the drain tray is emptying during routine visits
- Keep the certificate and photo report with the plant records
- Watch for drips or damp patches near the plant
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
Do you need AHU cleaning in Wooburn Green?
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
These are the problems we see most often:
- Fan sections that haven’t been cleaned in years
- Stale or musty smells from the ventilation
- Intake sections clogged with outdoor debris
- Drain trays holding standing water
School buildings such as Wooburn Green Primary School are usually done in the holidays, so classrooms aren’t disturbed.
