AHU cleaning for kitchens and businesses in South Weirs
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. If you’re dealing with stale or musty smells from the ventilation and dust-coated heating and cooling coils, we can help, from supply and extract fans, dampers and louvres and filter sections onwards.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
The paperwork matters as much as the work. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Between visits
A little care between visits keeps the system in better shape. We recommend:
- Make sure the unit’s access doors open easily
- Flag stale or damp smells in the supply air
- Make sure condensate is draining away
- File each AHU report in the maintenance log
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
What we do, step by step
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere as small as South Weirs, the date and timings are agreed with you well before the day.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Arrange a key holder or contact on site
- Tell us about site rules, permits or sign-in
- Clear the space around the work

Your questions about AHU cleaning in South Weirs
Do you cover South Weirs for AHU cleaning?
Yes. Our area runs across London and the South East, South Weirs included. Just call 0345 646 2711 or email us with a few details of the site.
Will you come out to South Weirs?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
How much notice should we give?
The more notice, the better, particularly for night and weekend visits. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
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 on one programme. Every site has its own report.
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 quote for both.
Do you survey before quoting?
Yes. We always survey first, either from photos and details you send or on a site visit. Then you get a fixed quote.
What do you clean inside the unit?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.
What does TR19 mean?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
In-house cleaning or a specialist?
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 grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Different parts, different methods
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. The intake section gets particular attention.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.

When to call us in South Weirs
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and slime and smells soon follow.
Common reasons sites call us are:
- Units that have only ever had filter changes
- Drain trays holding standing water
- Dirty fans and fan housings
- Rooms that smell stuffy when the system runs
If you manage a school such as Brockenhurst Church of England Primary School, ventilation cleaning is best booked for the holidays.
