AHU cleaning in Kencot
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. Common call-outs are for fan sections that haven’t been cleaned in years and dirty filters cutting the airflow, across drain trays, dampers and louvres and filter sections.
Work in a small place like Kencot starts with agreeing access and timings.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Aftercare tips
Here’s the after-treatment advice, in brief:
- Do not store bins or materials near the intake
- Note any water around the unit or leaks below it
- Flag stale or damp smells in the supply air
- File each AHU report in the maintenance log
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can survey both.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
Why deal with it now?
If people in a building in Kencot complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. Systems in rural buildings are often out of sight and out of mind.
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, give us a ring on 0345 646 2711, or email photos and we will give you an honest view and a fixed quote.

Your questions about AHU cleaning in Kencot
Can a school’s ventilation in Kencot be done out of term time?
Yes, and it’s the easiest time to do it. Around Kencot, the Food Standards Agency lists about 3 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
Is Kencot within the area you cover?
Yes. Kencot is within the area we cover across London and the South East. A survey first, from photos or a visit, means we arrive with the right kit.
Can you clean the AHU out of hours?
Yes. We work evenings, overnight and weekends, so the building keeps running in the day.
What’s TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
How much notice should we give?
The more notice, the better, especially for out-of-hours work. Quotes normally come back within one working day, and emergencies are covered by our 24/7 line.
Do you repair air handling units?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report for your maintenance team to follow up.
Where does the waste go?
We take it away when we go. During the work, it’s contained to keep the area clean.
Can one contract cover all our sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Every site has its own report.
What staff can safely do
Staff cleaning and specialist work aren’t the same thing. 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.
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.
Kencot buildings and their air
The FSA’s food hygiene register lists about 3 schools, colleges and universities with registered kitchens or food service in Kencot and the streets around it, up to about 1.5 miles out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. About 5.9 miles south of Kencot is Longworth Hospital, the nearest hospital. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
Healthcare ventilation, from large hospitals like Longworth Hospital (about 5.9 miles south) to small clinics, depends on clean filters, coils and ducts.
Kencot is about 2 miles south-west of Carterton, in Oxfordshire.

Common problems we fix in Kencot
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and that is where slime and odours start.
Common reasons sites call us include:
- Filters that are clogged or overdue
- Plant that has been serviced but not cleaned
- Fan sections that haven’t been cleaned in years
- Dirty coils holding back the airflow
If you manage a school such as St Peter's Church of England School, ventilation cleaning is best booked for the holidays.
What to look for in a quote
- Exactly which parts of the system are covered
- Whether inaccessible sections are listed on the report
- Whether they recommend a next date
- Proof of insurance
How it works
Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes half a day to a full day per unit, with large plant planned over several shifts. Rural roads and tight entrances are worth telling us about before a visit to Kencot.
- We survey the unit from photos 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 are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Let us know about permits to work or site inductions
- Let us know how we reach the system, including roofs, risers and plant rooms
- Find the previous report, if there is one
Get a fixed quote
To get a fixed quote, give us a ring on 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. We normally come back within one working day.
