AHU cleaning in Wootton, done properly
If the units serving a building in Wootton have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. The work covers drain trays, dampers and louvres and internal panels, and the jobs we see most are blocked condensate drains and slimy trays and dirty filters cutting the airflow.
For a building in or near Wootton, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
What the work involves, part by part
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
Honest limits
We’d rather tell you now than book work that will not help, so here are the limits:
- Breakdowns that need a mechanical engineer
- Damaged coils beyond cleaning
- Ductwork downstream of the unit, which is a separate clean
If you are not sure, just give us a ring on 0345 646 2711, or email photos and we will give you a straight answer.
Parts of the system we cover
- Drain trays
- Filter sections
- Internal panels
- Supply and extract fans
- Heating and cooling coils
- Dampers and louvres
What we do, step by step
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. The work itself takes anything from half a day for one small unit to several shifts for a plant room full of them. For a village or hamlet like Wootton, tell us about narrow lanes, gates and parking when you book.
- We survey the unit from pictures or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after pictures.
Preparing for the visit
- Clear the space around the work
- Make sure equipment near the work can be switched off and left to cool
- Name a contact who can let us in at the agreed time
Ask for a quote
Getting a quote does not take long. Send a few details and pictures, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

What happens if it’s left?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that does not feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. Our emergency line runs 24/7, but a planned visit to Wootton is calmer for everyone.

Aftercare tips
Looking after the system between visits is straightforward, and it helps at the next visit:
- File each AHU report in the maintenance log
- Keep the area around the fresh air intake clear
- Make sure the unit’s access doors open easily
- Report water on the plant room floor
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.

What does TR19 mean?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
How long does an AHU clean take?
As a guide, it takes anything from half a day for one small unit to several shifts for a plant room full of them. We plan the shutdown around that, out of hours if needed.
Do you give a certificate after the clean?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
Can you price the work without visiting?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
