- Drain trays holding standing water
- Filters that are clogged or overdue
- Air handling units due a clean after building work
Different parts, different methods
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
How we handle AHU cleaning in Ewelme
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. The work covers drain trays, supply and extract fans and heating and cooling coils, and people most often call us about intake sections clogged with outdoor debris and drain trays holding standing water.
Somewhere as small as Ewelme, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
The sign-off is always in writing: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Signs you need AHU cleaning in Ewelme
An overdue filter loads up with dirt, 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:
- Dirty fans and fan housings
- Odours coming through the supply air
- Units needing a clean before a new tenant or handover
- Condensate trays that will not empty
Wherever a school like Ewelme CofE Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
What your quote should include
- How areas they can’t reach will be recorded
- Proof of accreditation you can verify
- Whether they recommend a next date
- When they can work, and whether that’s outside your opening hours
Why act early in Ewelme
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, particularly where damp has made it stick. It’s simpler to plan the work at Ewelme now than to arrange it in a hurry later.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, phone us on 0345 646 2711, or email photos and we will give you an honest view and a fixed quote.
What you get with us
- Work around your opening hours, with 24/7 emergency cover
- Ventilation hygiene specialists since 2009
- Full insurance on every job
- Photo reports with every job

Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.

How it works
Each visit runs to the same pattern: protect the area, isolate whatever needs isolating, do the work, clear away and hand over the paperwork. The visit itself takes one overnight shift for many single units, with bigger plant phased. Photos of the system and how to reach it help us plan a visit to Ewelme.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Before we arrive
- Find the previous report, if there is one
- Move anything stored near the system
- Mention any sign-in, permit or induction we need

What your team can do, and what needs us
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
