AHU cleaning in Dunton Green
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from photos or a site visit, and send you a fixed quote, so you know where you stand. Common call-outs are for dust built up on fan impellers and odours coming through the supply air, on heating and cooling coils, dampers and louvres and filter sections.
Work in a small place like Dunton Green starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Looking after it afterwards
So the system stays in good health:
- Don’t store bins or materials near the intake
- Report water on the plant room floor
- Don’t ignore odours coming through the grilles
- Make sure the unit’s access doors open easily
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
When it’s something else
It’s worth knowing the limits before booking:
- Building management system faults
- A system that is undersized for the building
- Coils that are corroded or leaking and need replacing
Not sure which it is? You can ring 0345 646 2711, or send details by email and we will tell you honestly before booking.
Parts of the system we cover
- Internal panels
- Supply and extract fans
- Dampers and louvres
- Heating and cooling coils
- Filter sections
- Drain trays
The process
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. Most of the time goes on the work itself, and that takes a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere like Dunton Green, lanes, gates and parking are worth mentioning in advance.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Move anything stored near the system
- Allow time for equipment near the work to be turned off and cool down
- Let us know when the site is closed or quiet
Getting a quote
To help us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Once you have those, call 0345 646 2711, or send details by email.

What affects the cost of AHU cleaning
Before we fix a price, we need to know a few things. We check:
- Whether several sites go on one quote
- Access, including roofs, risers and ceiling voids
- How big the system is
- Working hours and out-of-hours timing
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, call us on 0345 646 2711 or use the quote form and we’ll give you an honest view and a fixed quote.
Asking for a quote
There’s no need for technical detail. It helps if you can send:
- Your last certificate, test record or report
- Any access panels or hatches you can see
- Problems your staff have spotted
- The roof, plant room or outside wall the system runs to
We don’t publish a price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, call us on 0345 646 2711 or send us an email.

What staff can safely do
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Dunton Green: your questions answered
Do you do school ventilation cleaning in Dunton Green in the summer holidays?
Yes. The holidays are the usual time for school work. There are about 12 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Dunton Green. Just call 0345 646 2711, or send details by email with your term dates and we will plan around them.
Can you come to Dunton Green after we close?
Yes. We work evenings, overnight and at weekends. That way a site in Dunton Green does not have to lose a day’s trading. Your opening times are the first thing we ask for.
Which sectors do you work in?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
When should our AHU next be cleaned?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and the report recommends a next date.
Can you price the work without visiting?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Is there a survey before the work?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Do you repair air handling units?
The clean includes noting faults, but repairs sit with your maintenance contractor, with pictures where it helps.
What if parts of the system cannot be reached?
The report shows them clearly. In ductwork, new access panels are often the answer, which we can install.
Different parts, different methods
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. Cleaning restores the open path through the fins.
