About our AHU cleaning in Wendens Ambo
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. Typical jobs include condensate trays that won’t empty and dirty filters cutting the airflow, across internal panels, dampers and louvres and filter sections.
Work in a small place like Wendens Ambo starts with agreeing access and timings.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
Why deal with it now?
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. Equipment tucked in a roof space or outbuilding near Wendens Ambo rarely gets looked at unless someone books it.
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.
What you get with us
- Evenings, overnight and weekends, plus 24/7 emergency callout
- Fully insured
- Photo reports with every job
- Ventilation hygiene specialists since 2009

Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted.

Your questions about AHU cleaning in Wendens Ambo
Do you cover smaller places like Wendens Ambo?
Yes. Wendens Ambo is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
Can a school’s ventilation in Wendens Ambo be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. Around Wendens Ambo, the Food Standards Agency lists about 6 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you call us on 0345 646 2711 or send us an email, and we will fit the work in.
Can you price the work without visiting?
Normally, yes. Send a few wide photos plus close-ups of panels, filters or grilles, and we typically come back within one working day. If photos are not enough, we will survey first.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
What do you clean inside the unit?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
What if parts of the system can’t be reached?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
How long does an AHU clean take?
Expect it to take a single shift for a typical unit, longer for large or heavily soiled ones. The unit’s size and condition make the biggest difference, and we will confirm the time when we quote.
Looking after it afterwards
Aftercare is simple, and it helps at the next visit:
- Watch for drips or damp patches near the plant
- Plan the next inspection before the last report gets filed away
- File each AHU report in the maintenance log
- Flag stale or damp smells in the supply air
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.

Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
