How we handle AHU cleaning in Shirburn
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. The work covers drain trays, internal panels and supply and extract fans, and common reasons people get in touch are dust-coated heating and cooling coils and dust built up on fan impellers.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Questions from Shirburn
Do you clean school ventilation in Shirburn in the holidays?
Yes, holiday work suits schools best. The FSA’s register shows about 3 schools and colleges with food registrations within roughly a mile and a half of Shirburn. Send us your term dates when you call us on 0345 646 2711 or send us an email, and we’ll fit the work in.
Can you get to a site in Shirburn?
Yes, we work in villages as well as towns, and Shirburn is covered. Let us know about access, parking and anything unusual about getting there when you book.
Which accreditations do you hold?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we’re fully insured.
Do you have insurance?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
How often do AHUs need cleaning?
That is set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Can you price the work without visiting?
Yes, for many jobs. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote normally follows within one working day. Some sites still need a visit, and we will say so.
How much notice should we give?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
What happens to the waste?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it does not spread.
Managing agents and facilities teams in Shirburn
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
The process
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 anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere as small as Shirburn, the date and timings are agreed with you well before the day.
- 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, 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.
How to prepare
- Name a contact who can let us in at the agreed time
- Plan for cooking equipment or plant to be off before we arrive
- Find the previous report, if there is one
Ask for a quote
Quotes are quick. Send a few details and photos, 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.
Advice
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Aftercare tips
Once we have finished, these simple steps help:
- Note any water around the unit or leaks below it
- Clear leaves and litter away from the intake
- Book the next check in line with the report
- Report stiff or damaged access doors
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
Why act early in Shirburn
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, particularly where damp has made it stick. Equipment tucked in a roof space or outbuilding near Shirburn rarely gets looked at unless someone books it.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
What you get with us
- A fixed price before any work starts
- One number for every site across the South East and London
- Work around your opening hours, with 24/7 emergency cover
- Trading since 2009
