Air handling unit cleaning in Banbury, Oxfordshire
Looking for AHU cleaning in Banbury? We diagnose first, fix the price and book the work around your hours, finishing with a written report and photos.
- Fan sections that haven’t been cleaned in years
- Coils clogged with dust and debris
- Odours coming through the supply air
What staff can safely do
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
AHU cleaning in Banbury
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. If you have dirty fans and fan housings and units needing a clean before a new tenant or handover, we can put it right, from supply and extract fans, drain trays and filter sections onwards.
Many schools and offices in a town like Banbury have a mix of older and newer ventilation. The work starts with an inspection to decide what needs cleaning, so you are not paying for more than the system needs.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

The process
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. From there, it takes from a few hours for a compact unit to a day or more for a large one. Work in Banbury is usually booked after closing, early in the morning or on a closed day.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about parking and loading
- Tell us the best time to work, such as after service or at a weekend

Advice
Ventilation in Banbury buildings
The FSA’s food hygiene register lists about 10 schools, colleges and universities, about 22 care, childcare and hospital premises and about 11 hotels and guest houses with registered kitchens or food service within roughly a mile and a half of the centre of Banbury. Busy, occupied buildings like these are where clean supply air matters most. For Banbury, the closest hospital is Horton General Hospital, roughly 0.8 miles south-east. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
If you run a surgery, dental practice or care home near Banbury, clean ventilation matters as much to you as to a hospital like Horton General Hospital (about 0.8 miles south-east). If you run an office near Banbury station, its supply ductwork can gather dust for years before anyone looks inside.

What happens if it’s left?
If people in a building in Banbury complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. A small fault found now is a quick job; the same fault found later can close the site.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.

What the work involves, part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and report anything about the tray or drain that needs fixing.
Do you need AHU cleaning in Banbury?
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and that’s where slime and odours start.
What we’re most often called out for:
- Plant that needs cleaning after a refit
- Air handling units never cleaned inside
- Filters that are clogged or overdue
- Rooms that smell stuffy when the system runs
School buildings such as St Mary's Church of England Primary School are usually done in the holidays, so classrooms aren’t disturbed.
Questions to ask before booking
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether the quote shows VAT
- Whether a survey comes first
- Whether inaccessible sections are listed on the report
Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.

Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 10 schools, colleges and universities with registered kitchens within about a mile and a half of Banbury. Booking early in the term gives the best choice of holiday dates.
Can you come to Banbury after we close?
Yes. We work evenings, overnight and at weekends. It means the site in Banbury keeps running as normal. When you phone us on 0345 646 2711 or email us, mention when the site is quiet.

What if parts of the system can’t be reached?

Will the ventilation be off while you clean?
Yes, while the clean is under way. Out-of-hours work is available so the building is not left without ventilation when it’s busy.
