Part by part
Fans and fan sections
Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that won’t bend or flatten the fins.
AHU cleaning for kitchens and businesses in Kiddington
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. The work covers filter sections, drain trays and supply and extract fans, and people most often call us about dirty filters cutting the airflow and odours coming through the supply air.
Somewhere as small as Kiddington, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Kiddington questions
Do you offer AHU cleaning in Kiddington?
Yes. We work across London and the South East, and Kiddington is part of that. Get in touch with the details and we will arrange a survey.
Do you work at weekends in Kiddington?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. When you call us on 0345 646 2711 or drop us a line, mention when the site is quiet.
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.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
What about areas you cannot get to?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
How often should an air handling unit be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Do you need to switch the unit off?
Yes, while the clean is under way. We can work evenings, overnight or at weekends so the building is not left without ventilation when it’s busy.
Managing agents and facilities teams in Kiddington
If you look after several sites, 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.
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
The process
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. The work itself takes half a day to a full day per unit, with large plant planned over several shifts. Pictures of the system and its access let us plan the work in Kiddington before we set off.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Have your last certificate or report to hand
- Clear loose items from the work area
- Name a contact who can let us in at the agreed time

What affects the cost of AHU cleaning
There’s no set price list, because no two systems are the same. The quote depends on:
- One-off work versus a regular cycle
- Working hours and out-of-hours timing
- The condition we find in the survey
- How big the system is
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. You will have a fixed price before work begins.
Helping us quote
Many jobs can be priced from photos and some basics. Useful things to send:
- Any symptoms, from odd noises to smells or leaks
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Photos showing the whole system and its surroundings
- Detail shots of panels, filters and grilles
We do not publish a price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, phone us on 0345 646 2711 or drop us a line.
Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.

Do you need AHU cleaning in Kiddington?
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Kiddington, that is air they breathe for hours at a time.
It’s time to book a visit if you see:
- Intake sections clogged with outdoor debris
- Filters that are clogged or overdue
- Rooms that smell stuffy when the system runs
- Air handling units due a clean after building work
Around Kiddington, as anywhere, ventilation cleaning begins with an inspection.
