AHU cleaning in Iffley
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. The work covers heating and cooling coils, drain trays and internal panels, and common reasons people get in touch are odours coming through the supply air and plant that needs cleaning after a refit.
For a building near Iffley, the visit is planned around how it’s used, and the journey is planned ahead. The method does not change: inspect first, clean, then record what was done.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

The process
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Your opening hours decide when we come to Iffley, not ours.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- 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.
How to prepare
- Tell us about site rules, permits or sign-in
- Let us know about parking and loading
- Arrange a key holder or contact on site

Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

Aftercare tips
Results last longer with the right care. We suggest:
- Flag stale or damp smells in the supply air
- Check the drain tray is emptying during routine visits
- Report stiff or damaged access doors
- Keep the area around the fresh air intake clear
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. Keep both with the building’s maintenance records.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
What the work involves, part by part
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
When to call us in Iffley
Filters that are not changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
These are the problems we see most often:
- Dust-coated heating and cooling coils
- Odours coming through the supply air
- Air handling units with blocked filters
- Plant that needs cleaning after a refit
If you run a surgery, dental practice or care home near Iffley, clean ventilation matters as much to you as to a hospital like NHS Oxfordshire Clinical Commissioning Group (about 0.9 miles east).
What your quote should include
- Whether the price is fixed
- What records you’ll receive afterwards
- Whether the whole system is included, or only the parts that are easy to reach
- Whether inaccessible sections are listed on the report
Why deal with it now?
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. It also means the next inspection has less to find. A site near Iffley that has to close at short notice is hard to cover for.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will go through it with you.
Why book with us
- A written report with pictures after every visit
- Every job surveyed first

What to send for a quote:
- Close-ups of filters, grilles, hatches or access panels
- Any previous report or certificate

In-house cleaning or a specialist?
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to 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 they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Common questions in Iffley
Can the work in Iffley be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Your opening times are the first thing we ask for.
Can you clean school ventilation in Iffley during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 18 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Iffley. Just call us on 0345 646 2711 or email us with your term dates and we will plan around them.
How often do AHUs need cleaning?
That’s set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
What does TR19 mean?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
What does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, normally ready within one working day.
Can you set up regular visits?
Yes, of course. Send details of the systems and how they’re used, and we’ll suggest a schedule and quote for it.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
Do you cover Iffley?
Yes. Our area takes in London and the counties of South East England, and that includes Iffley.
