AHU cleaning in West Hagbourne
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. If you have blocked condensate drains and slimy trays and dust built up on fan impellers, we can put it right, from drain trays, heating and cooling coils 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. You get a written report with photos after each visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Between visits
Once we’ve finished, these simple steps help:
- Plan the next inspection before the last report gets filed away
- Flag stale or damp smells in the supply air
- Make sure the unit’s access doors open easily
- Keep the certificate and photo report with the plant records
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
Staff cleaning versus specialist work
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.
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 is our job.
How it works
Night work is normal for us. 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 half a day to a full day per unit, with large plant planned over several shifts. A few pictures of the system help us make the most of a visit to a place like West Hagbourne.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Make sure equipment near the work can be switched off and left to cool
- Agree a time when the area can be out of use

Leave it or put it right?
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. If the system at a site near West Hagbourne fails, there may be nowhere nearby to move to.
The cost depends on how big the system is, what state it’s in and how easy it is to reach. You get a fixed price before we start, so there are no surprises.

Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
Which parts of an air handling unit do you clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
How do you protect the area?
Floors and surfaces near the work are sheeted before work begins, and anything we remove is contained. Before we leave, we tidy up and clean down.
What does TR19 mean?
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.
Do you need to switch the unit off?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.
When to call us in West Hagbourne
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in West Hagbourne, that is air they breathe for hours at a time.
The symptoms we’re asked about most are:
- Plant that has been serviced but not cleaned
- Intake sections clogged with outdoor debris
- Condensate trays that won’t empty
- Coils clogged with dust and debris
Wherever a school like Hagbourne Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
