Questions from Dunton
Do you work at weekends in Dunton?
Yes, we can come after you close and finish before you open. The work in Dunton can fit around your hours. Just call us on 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
Can you get to a site in Dunton?
Yes. Villages and rural sites across the South East are part of our work, Dunton included. The journey is planned ahead, so a few details about the route help.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. We’ll tell you after the survey whether the ducts need it.
How far ahead should we book?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: 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.
Can you look after several sites?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
Do you offer emergency callouts?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
AHU cleaning in Dunton, done properly
Our AHU cleaning covers sites in Dunton and the rest of Buckinghamshire, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. If you are dealing with plant that needs cleaning after a refit and leaves and litter drawn into the unit, we can help, from dampers and louvres, internal panels and drain trays onwards.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Good records are part of the job. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Different parts, different methods
Drain trays
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
Leave it or put it right?
Dirt left in an air handling unit does not stay in the unit. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. In a small place like Dunton, a system that fails can take a site out of use.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.

Take a look at what affects the cost or our accreditations and certificates.
In-house cleaning or a specialist?
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, alongside our reports.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
How it works
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. From there, it takes half a day to a full day per unit, with large plant planned over several shifts. If the van will struggle with a lane or gateway near Dunton, let us know and we’ll plan around it.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
How to prepare
- Clear the space around the work
- Mention any parking or loading restrictions
- Mention any locked doors, roof access or ceiling voids
Ask for a quote
Quotes are quick. Send a few details and pictures, 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
Signs you need AHU cleaning in Dunton
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
The symptoms we’re asked about most include:
- Dust built up on fan impellers
- Plant that has been serviced but not cleaned
- Air handling units with blocked filters
- Condensate trays that will not empty
Hospitals such as Tindal Centre (about 6 miles south) show how much a building can rely on clean ventilation, and smaller healthcare sites near Dunton are no different.
Comparing quotes
- What insurance they carry
- Whether the whole system is included, or only the parts that are easy to reach
- When the next visit should be, and why
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor

Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Change filters on schedule and log each change
- Note any water around the unit or leaks below it
- Keep inspection doors on the unit in good order
- Store the TR19 paperwork where auditors can find it
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
