In-house cleaning or a specialist?
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
AHU cleaning for kitchens and businesses in Upper Arncott
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from photos or a site visit, and send you a fixed quote, so you know where you stand. We’re often asked to deal with air handling units with blocked filters and air handling units due a clean after building work, across supply and extract fans, heating and cooling coils and dampers and louvres.
For a building in or near Upper Arncott, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Landlords, agents and facilities managers
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
What happens on the day
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Seeing the system in photos first means the trip to Upper Arncott can be planned properly.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- 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.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Let us know about permits to work or site inductions
- Clear the space around the work

Signs you need AHU cleaning in Upper Arncott
Filters that are not changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
These are the problems we see most often:
- Air handling units with blocked filters
- Plant that has been serviced but not cleaned
- Odours coming through the supply air
- Units needing a clean before a new tenant or handover
Bicester Community Hospital, about 3.7 miles north-west, is the nearest hospital to Upper Arncott, and healthcare sites of every size need their supply air kept clean.

What affects the cost of AHU cleaning
You will get a fixed price before any work starts. It’s based on:
- What state the system is in
- How easy every part is to reach
- The times the site is available
- A single visit or a regular plan
You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.
What to send for a quote
Photos let us diagnose from a distance. Try to include:
- Close-ups of filters, grilles, hatches or access panels
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your last certificate, test record or report
- Where the plant sits or the system leaves the building, such as a roof or outside wall

Questions from Upper Arncott
Will you come out to Upper Arncott?
Yes, we work in villages as well as towns, and Upper Arncott is covered. Just mention lanes, gates or anything else about the site when you book.
Do you clean school ventilation in Upper Arncott in the holidays?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Upper Arncott. Tell us your holiday dates and we’ll book the visit for when the site is empty.
How long does it take to clean an air handling unit?
Typically the clean takes one overnight shift for many single units, with bigger plant phased. We plan the shutdown around that, including evenings or weekends.
What accreditations do you have?
Duct Doctor is 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.
Can you quote from photos?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
When should our AHU next be cleaned?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and we will suggest an interval after the first clean.
Do you need to switch the unit off?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
Are you insured?
Yes. We carry full insurance, and we’ve been trading since 2009.

Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Report musty smells from the vents straight away
- Do not store bins or materials near the intake
- Look at the condensate drain whenever the unit is serviced
- Book the next check in line with the report
The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
