About AHU cleaning in Oxfordshire

Where a building in Oxfordshire has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. The work covers filter sections, supply and extract fans and drain trays, and common reasons people get in touch are debris and leaves in the fresh air intake and units that have only ever had filter changes.

Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows.

We agree a shutdown window that suits the building.
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.
After pictures are taken and the certificate issued.

AHU cleaning across Oxfordshire: local notes

Our AHU cleaning work across Oxfordshire takes in places such as Oxford, Banbury and Didcot and well beyond. We cover every place we list for Oxfordshire, 443 in all.

In England, the Fire Safety Order puts the duty on the responsible person to assess and reduce fire risk, and each certificate and photo report is a record you can keep in your log book.

Oxford: For schools like East Oxford Primary School, the holidays are the usual time to inspect and clean ventilation. If you run a surgery, dental practice or care home near Oxford, clean ventilation matters as much to you as to a hospital like Warneford Hospital (about less than half a mile east).

What we are called out for in Oxfordshire

Filters that are not 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.

Common reasons sites call us are:

Dirty filters cutting the airflow
Condensate trays that won’t empty
Fan sections that haven’t been cleaned in years
Coils clogged with dust and debris

Managing agents and facilities teams in Oxfordshire

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.

Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.

Leave it or put it right?

A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Oxfordshire simpler.

What your quote should include

Whether they recommend a next date
What happens if part of the system can’t be accessed
Whether a written report and photos are included
If they look at the system before pricing

Part by part

Fans and fan sections

Before the fan is touched, the unit is shut down and made safe in agreement with the site.

Heating and cooling coils

Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.

Honest limits

Before you book, it helps to know what’s not included:

Leaking heating or cooling coils
Dirty ducts beyond the unit itself
Building management system faults

Oxfordshire questions

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 cover Oxfordshire?

Yes. Our area takes in London and the counties of South East England, and that includes Oxfordshire.

Do you give a certificate after the clean?

Yes, both a certificate and a report with photos. The report also suggests when the unit should next be inspected.

Do you look at the system first?

Yes. Photos often do the job, and larger or hidden systems get a visit.

When should our AHU next be cleaned?

TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. Each report suggests when the unit should next be looked at.

Does the AHU have to be shut down for cleaning?

Yes. We can’t clean a running unit, so it’s switched off and made safe first. The shutdown is planned with whoever runs the building.

Which kinds of sites do you work on?

Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
