About our AHU cleaning in Brightwell Baldwin
We clean air handling units for buildings in Brightwell Baldwin and across Oxfordshire, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. We are often asked to deal with units needing a clean before a new tenant or handover and air handling units never cleaned inside, across drain trays, internal panels and filter sections.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What staff can safely do
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.

Different parts, different methods
Drain trays
Older trays can corrode and start leaking. Their condition goes into the report with photos so you can decide on any repairs.
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 we do, step by step
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. From there, it takes a single shift for a typical unit, longer for large or heavily soiled ones. Photos of the system and how to reach it help us plan a visit to Brightwell Baldwin.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Mention any parking or loading restrictions
- Find the previous report, if there is one
- Mention any sign-in, permit or induction we need

Keeping the system healthy
No system stays clean for ever, but care slows the build-up. A few tips:
- Report stiff or damaged access doors
- Clear leaves and litter away from the intake
- 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. Record each change in the maintenance log.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
Common problems we fix in Brightwell Baldwin
Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Signs it’s time to call us include:
- Intake sections clogged with outdoor debris
- Stale or musty smells from the ventilation
- Blocked condensate drains and slimy trays
- Air handling units never cleaned inside
In Brightwell Baldwin, we look inside the system before deciding what needs cleaning.
