AHU cleaning in Hangleton, done properly
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. We’re often asked to deal with units needing a clean before a new tenant or handover and leaves and litter drawn into the unit, on supply and extract fans, dampers and louvres and drain trays.
For a building in or near Hangleton, access is agreed in advance and the visit is planned around the journey.
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.

What your team can do, and what needs us
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
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 will take a look and give you a fixed quote.

How the visit works
Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. The visit takes half a day to a full day per unit, with large plant planned over several shifts. We agree a date with you, plan the drive to Hangleton and turn up when the site is quiet.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Make sure equipment near the work can be switched off and left to cool
- Tell us the best time to work, such as after service or at a weekend
How to get a quote
Quoting starts with a diagnosis, 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 work begins.

Why act early in Hangleton
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. In a small place like Hangleton, a system that fails can take a site out of use.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, call 0345 646 2711 or email us for straight advice and a fixed quote.

FAQs for Hangleton
Can you clean school ventilation in Hangleton during the holidays?
Yes. The holidays are the usual time for school work. With about 13 schools and colleges on the FSA’s register within roughly a mile and a half of Hangleton, it pays to plan holiday dates ahead. Send us your term dates when you ring 0345 646 2711, or email photos, and we’ll fit the work in.
Will you come out to Hangleton?
Yes, Hangleton is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Can you clean the AHU out of hours?
Yes. The clean is planned around when the unit can be switched off. In hospitals and care homes, we agree timings with the site team.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
What’s included in an AHU clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.
What should I send you?
A short description and a few photos plus the address and your hours. We’ll ask for anything else we need.
What do you do with what you remove?
It leaves the site with us at the end of the visit. While we work, it’s kept contained so the area stays clean.
How much notice should we give?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
What affects the cost of AHU cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- Site rules, permits and inductions
- Access, including roofs, risers and ceiling voids
- A single visit or a regular plan
- How big the system is
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before we start.
Helping us quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Where the site is and what kind of site it is
- The paperwork from the last visit, if you have it
- Any access panels or hatches you can see
- A few general shots of the system
For a fixed quote, ring 0345 646 2711 or use the quote form with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.
What AHU cleaning looks like in Hangleton
There are about 13 schools, colleges and universities and about 14 caring premises (care homes, nurseries and hospitals) on the FSA’s food hygiene register in and around Hangleton, up to about a mile and a half out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Hangleton, about 49 miles from central London, is within our usual area. Visits are booked around your hours, evenings and weekends included. Zachary Merton Hospital is the nearest hospital, about 2.1 miles south-west of Hangleton. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
Wherever a school like Ferring CofE Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Between visits
No system stays clean for ever, but care slows the build-up. A few tips:
- Diary the inspection date recommended in the report
- Stick to the filter change plan
- Watch for drips or damp patches near the plant
- Look at the condensate drain whenever the unit is serviced
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
When something else is needed
To be straight with you, some problems need a different fix:
- Ventilation that was badly designed in the first place
- Building management system faults
- Breakdowns that need a mechanical engineer
If you’re not sure, just give us a ring on 0345 646 2711 or email us and we will give you a straight answer.
What the work covers
- Heating and cooling coils
- Internal panels
- Filter sections
- Supply and extract fans
- Drain trays
- Dampers and louvres
What we’re called out for in Hangleton
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Most sites get in touch after spotting one of these:
- Drain trays holding standing water
- Plant that has been serviced but not cleaned
- Dirty filters cutting the airflow
- Fan sections that haven’t been cleaned in years
If you run a surgery, dental practice or care home near Hangleton, clean ventilation matters as much to you as to a hospital like Zachary Merton Hospital (about 2.1 miles south-west).
