AHU cleaning in Watlington
Our AHU cleans for sites in Watlington cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. The work covers supply and extract fans, filter sections and internal panels, and common reasons people get in touch are coils clogged with dust and debris and rooms that smell stuffy when the system runs.
Around a place like Watlington, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Even a small system collects dust in its ducts and filters.
The report is your system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Landlords, agents and facilities managers
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
What a clean will not put right
We’d rather tell you now than book work that won’t help, so these are the things it will not cover:
- A system that is undersized for the building
- Ductwork downstream of the unit, which is a separate clean
- Building management system faults
If you are not sure, just call us on 0345 646 2711 or use the quote form and we will give you a straight answer before you book.
Parts of the system we cover
- Supply and extract fans
- Internal panels
- Drain trays
- Dampers and louvres
- Heating and cooling coils
- Filter sections
When to call us in Watlington
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
Signs it’s time to call us include:
- Dirty coils holding back the airflow
- Blocked condensate drains and slimy trays
- Units that have only ever had filter changes
- Rooms that smell stuffy when the system runs
For schools like Watlington Primary School, the holidays are the usual time to inspect and clean ventilation.

Watlington: your questions answered
Do you do school ventilation cleaning in Watlington in the summer holidays?
Yes, out-of-term visits are normal for schools. There are about 3 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Watlington. Send us your term dates when you ring 0345 646 2711 or use the quote form, and we’ll fit the work in.
Do you work at weekends in Watlington?
Yes. We work evenings, overnight and at weekends. The work in Watlington can fit around your hours. When you ring 0345 646 2711, or send details by email, mention when the site is quiet.
What happens if you cannot reach some of it?
Anything we cannot reach goes on the report, with photos where possible, and we explain what access is needed, such as extra access panels in ductwork.
Can you look after several sites?
Yes. Send the list of sites and the work at each and we will quote them together.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before we start, and waste is contained as we go. At the end, the area is cleaned down.
How much notice do you need?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, and new panels can be fitted.
Will the ventilation be off while you clean?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
Part by part
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey so the quote reflects it.
Keeping the system healthy
A little care between visits keeps the system in better shape. We recommend:
- Make sure condensate is draining away
- Diary the inspection date recommended in the report
- File each AHU report in the maintenance log
- Report stiff or damaged access doors
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
How the visit works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Your opening hours decide when we come to Watlington, not ours.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Before we arrive
- Dig out any earlier paperwork for the system
- Clear loose items from the work area
- Make sure someone can let us in and lock up afterwards

Advice
In-house cleaning or a specialist?
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
