- Plant that needs cleaning after a refit
- Air handling units with blocked filters
- Leaves and litter drawn into the unit
What happens on the day
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes from a few hours for a compact unit to a day or more for a large one. Somewhere like Cousley Wood, lanes, gates and parking are worth mentioning in advance.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure someone can let us in and lock up afterwards
- Have your last certificate or report to hand

Advice
About our AHU cleaning in Cousley Wood
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with photos, so the report shows exactly what was done. Common call-outs are for drain trays holding standing water and stale or musty smells from the ventilation, on heating and cooling coils, drain trays and supply and extract fans.
Somewhere as small as Cousley Wood, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
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, ready for your insurer.

Cousley Wood: your questions answered
Do you cover smaller places like Cousley Wood?
Yes. Villages and rural sites across the South East are part of our work, Cousley Wood included. Photos of the system and directions to the site help us plan the visit.
Do you work overnight in Cousley Wood?
Yes. We work evenings, overnight and at weekends. That way a site in Cousley Wood doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
What happens if you cannot reach some of it?
We record them on the report, with pictures where possible, and we tell you what would make it reachable, such as extra access panels in ductwork.
Can you price the work without visiting?
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.
How much notice should we give?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
How often should an air handling unit be cleaned?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
Where does the waste go?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
What we’re called out for in Cousley Wood
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that’s the air they breathe for hours on end.
What we’re most often called out for:
- Drain trays holding standing water
- Plant that has been serviced but not cleaned
- Air handling units with blocked filters
- Dirty fans and fan housings
Wherever a school like Uplands Community College has ducted ventilation, a half-term visit keeps the work out of lesson time.

What the work involves, part by part
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
What a clean will not put right
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning will not do:
- Ventilation that was badly designed in the first place
- Controls and BMS settings that run the unit
- Coils that are corroded or leaking and need replacing
If you’re not sure, just phone us on 0345 646 2711 or send us an email and we’ll give you a straight answer.
What the work covers
- Drain trays
- Filter sections
- Internal panels
- Heating and cooling coils
- Supply and extract fans
- Dampers and louvres
What happens if it’s left?
Standing water in a drain tray does not clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. It’s worth booking a check, because nobody sees inside a duct day to day.
The cost depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before work begins, so there are no surprises.

For landlords and multi-site operators
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
Staff cleaning versus specialist work
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
