AHU cleaning in Eton Wick
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. We’re often asked to deal with air handling units never cleaned inside and air handling units with blocked filters, on supply and extract fans, drain trays and internal panels.
For a building in or near Eton Wick, 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.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What else we do in Eton Wick
Questions from Eton Wick
Do you do school ventilation cleaning in Eton Wick in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 42 schools and colleges with food registrations within roughly a mile and a half of Eton Wick. Tell us your holiday dates and we will book the visit for when the site is empty.
Can you come to Eton Wick after we close?
Yes. We work evenings, overnight and at weekends. It means the site in Eton Wick keeps running as normal. Just call us on 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
What’s included in an AHU clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
Will we get paperwork for the AHU clean?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
Do you need to switch the unit off?
Yes. We can’t clean a running unit, so it’s switched off and made safe first. The shutdown is planned with whoever runs the building.
Is Eton Wick in your area?
Yes. Our technicians work in Eton Wick, within the South East and London area we cover.
Do you clean the ductwork as well?
Yes, the ductwork, grilles and diffusers the unit serves. We will tell you after the survey whether the ducts need it.
How do you keep the site clean during the work?
By covering it before any work starts. We keep the work contained and leave the area clean.
How the job changes from site to site
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
Internal casing and panels
We open each section through its doors and close them securely when we’re done before the unit is handed back.
What a clean will not put right
Not every problem is solved by AHU cleaning, and we’ll tell you before we start. It doesn’t solve:
- Controls and BMS settings that run the unit
- Airflow problems caused by the system’s design
- Ductwork downstream of the unit, which is a separate clean
If in doubt, phone us on 0345 646 2711, or send details by email and we will say what we think.
What the work covers
- Internal panels
- Heating and cooling coils
- Drain trays
- Supply and extract fans
- Filter sections
- Dampers and louvres
What AHU cleaning looks like in Eton Wick
The FSA’s food hygiene register lists about 42 schools, colleges and universities, about 12 hospitals, care homes and childcare premises and about 5 hotels and guest houses with registered kitchens or food service within about 1.5 miles of central Eton Wick. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Eton Wick’s nearest hospital, King Edward VII Hospital, is about 1.9 miles south-east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. About 23 miles out from central London, Eton Wick is part of the South East area we work across. Visits are booked around your hours, evenings and weekends included.
If you manage a school such as Eton Wick CofE First School, ventilation cleaning is best booked for the holidays. Healthcare ventilation, from large hospitals like King Edward VII Hospital (about 1.9 miles south-east) to small clinics, depends on clean filters, coils and ducts.

Looking after it afterwards
Simple habits between visits make a real difference. Our advice:
- Watch for drips or damp patches near the plant
- Stick to the filter change plan
- Report stiff or damaged access doors
- Report musty smells from the vents right away
The report suggests a date for the next inspection or clean, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
What we do, step by step
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a single shift for a typical unit, longer for large or heavily soiled ones. In a small place like Eton Wick, the journey is planned ahead and the visit arranged around the site’s hours.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Clear loose items from the work area
- Arrange a key holder or contact on site
- Tell us the best time to work, such as after service or at a weekend
Getting a quote
There’s no standard price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then give you a fixed quote. To get going, call us on 0345 646 2711 or send us an email.
Advice
What affects the quote in Eton Wick
Some jobs are bigger than they look, and some smaller. What affects the quote:
- One-off work versus a regular cycle
- The condition we find in the survey
- The scale of the work
- Any permits to work or inductions
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
What we need to know
A few details help us quote accurately. With your enquiry, please include:
- Wide pictures of the system and the area around it
- Your opening hours and when the area is out of use
- Problems your staff have spotted
- Close-ups of filters, grilles, hatches or access panels
Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and the last certificate or report, if there is one. Then call us on 0345 646 2711 or use the quote form.
Landlords, agents and facilities managers
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
