Oxfordshire · Air handling unit cleaning
Middle Assendon AHU cleaning
For air handling unit cleaning in Middle Assendon, one call is all it takes, from survey to sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Odours coming through the supply air
- Air handling units due a clean after building work
- Fan sections that haven’t been cleaned in years
Keeping the system healthy
So the system stays in good health:
- Do not store bins or materials near the intake
- Check the drain tray is emptying during routine visits
- File each AHU report in the maintenance log
- Plan the next inspection before the last report gets filed away
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
About our AHU cleaning in Middle Assendon
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. If you are dealing with intake sections clogged with outdoor debris and units needing a clean before a new tenant or handover, we can put it right.
Somewhere as small as Middle Assendon, ducted ventilation is usually 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.
Good records are part of the job. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Middle Assendon: your questions answered
Will you come out to Middle Assendon?
Yes. Middle Assendon is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Do you work at weekends in Middle Assendon?
Yes, evening, overnight and weekend work is normal for us. The work in Middle Assendon can fit around your hours. Just call us on 0345 646 2711 or email us with your opening times and we’ll plan around them.
How much notice do you need?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
Will the ventilation be off while you clean?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
Can you price the work without visiting?
Yes, for many jobs. Send a few wide pictures plus close-ups of panels, filters or grilles, and we usually come back within one working day. If photos aren’t enough, we’ll survey first.
Do you repair air handling units?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We’ll flag anything we notice during the clean.
How long will the unit be out of action?
Cleaning takes from a few hours for a compact unit to a day or more for a large one. Large plant can be split over several shifts, and you can call 0345 646 2711 or send us an email to plan it.
Multi-site and managed buildings
Facilities teams in offices, schools and healthcare sites book us too in Middle Assendon and across Oxfordshire. Work can be phased by floor, building or site to keep disruption down.

What AHU cleaning can’t fix
We’d rather tell you now than book work that won’t help, so here are the limits:
- Problems with the unit’s controls or sensors
- A system that is undersized for the building
- Damaged coils beyond cleaning
If in doubt, ring 0345 646 2711 or use the quote form and we’ll say what we think before booking.

How it works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before work begins, and the area around the work is covered and protected. The work itself takes half a day to a full day per unit, with large plant planned over several shifts. Pictures of the system and its access let us plan the work in Middle Assendon before we set off.

What staff can safely do
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Why deal with it now?
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, for audits, tenants or your own peace of mind. Our emergency line runs 24/7, but a planned visit to Middle Assendon is calmer for everyone.
