AHU cleaning in South Stoke, done properly
We clean air handling units for buildings in South Stoke and across Oxfordshire, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. We are often asked to deal with air handling units due a clean after building work and coils clogged with dust and debris, across supply and extract fans, drain trays and dampers and louvres.
Work in a small place like South Stoke starts with agreeing access and timings.
Think of the report as the 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.

Keeping the system healthy
After the visit, a few habits help the work last:
- Keep the certificate and photo report with the plant records
- Check the drain tray is emptying during routine visits
- Clear leaves and litter away from the intake
- Keep inspection doors on the unit in good order
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.

School buildings such as South Stoke Primary School are normally done in the holidays, so classrooms are not disturbed.

Common problems we fix in South Stoke
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and slime and smells soon follow.
What we are most often called out for:
- Stale or musty smells from the ventilation
- Filters that are clogged or overdue
- Intake sections clogged with outdoor debris
- Air handling units never cleaned inside
For buildings in and around South Stoke, TR19® Air cleaning starts with an inspection.
Questions to ask before you book
- Whether they’re fully insured
- How they set the interval to the next visit
- Which accreditations they hold, and whether you can check them
- How areas they can’t reach will be recorded
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 need training, the right equipment and safe access. Leave those to us.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.

Questions from South Stoke
Do you work in villages like South Stoke?
Yes. South Stoke is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Can you come to South Stoke after we close?
Yes, nights and weekends are routine for us. That way a site in South Stoke doesn’t have to lose a day’s trading. Let us know the hours you are closed and we will book within them.
Do you offer maintenance contracts?
Yes, of course. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed quote.
Will the ventilation be off while you clean?
Yes, while the clean is under way. Out-of-hours work is available to keep disruption down.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
Can you clean the ducts connected to the AHU?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, and new panels can be fitted.
How much notice do you need?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
When should our AHU next be cleaned?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and we’ll suggest an interval after the first clean.
Why act early in South Stoke
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. Systems in rural buildings are often out of sight and out of mind.

What happens on the day
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before we start, and floors and nearby surfaces are sheeted. On site, it takes anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere like South Stoke, lanes, gates and parking are worth mentioning in advance.
- First we agree when the unit can be switched off, including evenings or weekends.
- 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.
- We take after pictures and issue the certificate and report.
How to prepare
- Tell us about site rules, permits or sign-in
- Move anything stored near the system
- Dig out any earlier paperwork for the system
How to get a quote
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.
