How we handle AHU cleaning in Slindon
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. Common call-outs are for units that have only ever had filter changes and air handling units due a clean after building work, across dampers and louvres, heating and cooling coils and internal panels.
Somewhere as small as Slindon, ducted ventilation is usually 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 paperwork matters as much as the work. You get a written report with pictures after each visit, 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.

What your team can do, and what needs us
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
Landlords, agents and facilities managers
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.

What the work involves, part by part
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Store the TR19 paperwork where auditors can find it
- Flag stale or damp smells in the supply air
- Watch for drips or damp patches near the plant
- Check the drain tray is emptying during routine visits
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
How the visit works
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. The middle part takes longest, which takes anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere like Slindon, lanes, gates and parking are worth mentioning in advance.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after pictures.
Preparing for the visit
- Have your last certificate or report to hand
- Let us know when the site is closed or quiet
- Plan for cooking equipment or plant to be off before we arrive

Your questions about AHU cleaning in Slindon
Is Slindon within the area you cover?
Yes, we work in villages as well as towns, and Slindon is covered. A survey first, from pictures or a visit, means we arrive with the right kit.
Do you work at weekends in Slindon?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Slindon needn’t be disturbed. When you call us on 0345 646 2711 or send us an email, mention when the site is quiet.
What if parts of the system cannot be reached?
We record them on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Can you quote from photos?
In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Does the AHU have to be shut down for cleaning?
Yes. We cannot clean a running unit, so it’s switched off and made safe first. The shutdown is planned with whoever runs the building.
Is there a report after cleaning?
Yes, both a certificate and a report with pictures. The report also suggests when the unit should next be inspected.
What happens to the waste?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
