Air handling unit cleaning in Fiddlers Hamlet, Essex
AHU cleaning for businesses, landlords and public buildings in Fiddlers Hamlet. CHAS, SafeContractor and ISO 9001, and fully insured.
- Leaves and litter drawn into the unit
- Plant that needs cleaning after a refit
- Blocked condensate drains and slimy trays
How the job changes from site to site
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.
About our AHU cleaning in Fiddlers Hamlet
If the units serving a building in Fiddlers Hamlet have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. The work covers internal panels, supply and extract fans and dampers and louvres, and the jobs we see most are drain trays holding standing water and debris and leaves in the fresh air intake.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Good records are part of the job. Each visit is written up with photos, 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.

How it works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a single shift for a typical unit, longer for large or heavily soiled ones. Pictures of the system and its access let us plan the work in Fiddlers Hamlet before we set off.
- We look at the unit and the plant area during the survey.
- 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.
Getting ready for the visit
- Move anything stored near the system
- Agree a time when the area can be out of use
- Let us know about parking and loading

Between visits
Here’s the after-treatment advice, short and simple:
- Keep the area around the fresh air intake clear
- Report water on the plant room floor
- File each AHU report in the maintenance log
- Flag stale or damp smells in the supply air
The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
Why deal with it now?
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. A fault that closes a site in a village like Fiddlers Hamlet affects everyone who depends on it.
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before we start.

- Travel, parking and unloading
- The times the site is available
- How big the system is
- What state the system is in
You won’t find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will explain what it covers.
Asking for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- How we’d reach plant on a roof or in a plant room
- When the site is open and when it’s quiet
- Wide pictures of the system and the area around it
- Any access panels or hatches you can see
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.
Your questions about AHU cleaning in Fiddlers Hamlet
Can ventilation in schools around Fiddlers Hamlet be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 4 schools and colleges with food registrations within roughly a mile and a half of Fiddlers Hamlet. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Will you come out to Fiddlers Hamlet?
Yes. Fiddlers Hamlet is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Are you fully insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Can one contract cover all our sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Every site has its own report.
What does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote and we will typically reply within one working day.
Can you price the work without visiting?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Can you clean the ducts connected to the AHU?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can survey both on the same visit.
Will the ventilation be off while you clean?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.

When to call us in Fiddlers Hamlet
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Fiddlers Hamlet, that’s air they breathe for hours at a time.
If you notice any of these, it’s worth a diagnosis:
- Intake sections clogged with outdoor debris
- Drain trays holding standing water
- Air handling units with blocked filters
- Dirty fans and fan housings
Classrooms and halls at schools such as Ivy Chimneys Primary School are easiest to work in when pupils are away.
What your quote should include
- Whether they’re fully insured
- What happens if part of the system can’t be accessed
- How VAT is shown on the quote
- Whether the whole system is included, or only the parts that are easy to reach
