Stambourne Green AHU cleaning

Common problems we fix in Stambourne Green
Filters that aren’t changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
Signs it’s time to call us include:
- Stale or musty smells from the ventilation
- Air handling units never cleaned inside
- Dirty coils holding back the airflow
- Air handling units due a clean after building work
An inspection comes first for any ventilation job around Stambourne Green, so the cleaning matches what’s there.

How we handle AHU cleaning in Stambourne Green
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. If you’re dealing with odours coming through the supply air and blocked condensate drains and slimy trays, we can help, from heating and cooling coils, filter sections and dampers and louvres 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.
The report is your 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.

Why deal with it now?
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. A fault that closes a site in a village like Stambourne Green affects everyone who depends on it.
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and why the quote is fixed before work begins.
What you get with us
- Every job surveyed first
- A written report with pictures after each visit
- One contact for all your sites in London and the South East
- BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease

What AHU cleaning can’t fix
It’s worth knowing the limits before booking:
- Building management system faults
- Ductwork downstream of the unit, which is a separate clean
- Ventilation that was badly designed in the first place
If you are not sure, just give us a ring on 0345 646 2711, or send details by email and we’ll give you a straight answer.

What affects the quote in Stambourne Green
The quote reflects the site in front of us. We consider:
- How many systems or sites are involved
- Any permits to work or inductions
- How big the system is
- The times the site is available
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before any work starts.
Helping us quote
When you contact us, it’s useful to have:
- Problems your staff have spotted
- The site address and the type of premises
- Close-ups of filters, grilles, hatches or access panels
- Your last certificate, test record or report
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before work begins.

Related advice
Between visits
Aftercare is simple, and it makes the next visit easier:
- Don’t store bins or materials near the intake
- Diary the inspection date recommended in the report
- Keep inspection doors on the unit in good order
- Change filters on schedule and log each change
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
FAQs for Stambourne Green
Can the work in Stambourne Green be done at night or at weekends?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Stambourne Green needn’t be disturbed. Let us know the hours you are closed and we’ll book within them.
Is Stambourne Green in your area for AHU cleaning?
Yes, Stambourne Green is within the area we cover across London and the South East. Just give us a ring on 0345 646 2711 or use the quote form with a few details of the site.
What happens if you cannot reach some of it?
We record them on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Will we get paperwork for the AHU clean?
Yes. You get a TR19® certificate plus before and after photos. They’re worth keeping with the plant records.
Will the ventilation be off while you clean?
Yes, while the clean is under way. Out-of-hours work is available to keep disruption down.
Can you quote from pictures?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
What’s included in an AHU clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.
In-house cleaning or a specialist?
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
