AHU cleaning in South Hinksey
If the units serving a building in South Hinksey have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. Common call-outs are for debris and leaves in the fresh air intake and units that have only ever had filter changes, on internal panels, filter sections and supply and extract fans.
Somewhere as small as South Hinksey, 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.
A written report with pictures follows every visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
We also work for facilities teams across offices, schools and healthcare across Oxfordshire. Larger estates can be phased building by building around the people who use them.

What else we do in South Hinksey
What the work involves, part by part
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with photos.
What happens if it’s left?
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. A fault that closes a site in a village like South Hinksey affects everyone who depends on it.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
Why choose Duct Doctor in South Hinksey

What we’re called out for in South Hinksey
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
If you notice any of these, it’s worth a diagnosis:
- Dust built up on fan impellers
- Intake sections clogged with outdoor debris
- Condensate trays that won’t empty
- Coils clogged with dust and debris
Healthcare buildings such as Littlemore Hospital, about 1.9 miles south-east, depend on their ventilation; if you manage a surgery, clinic or care home near South Hinksey, yours matters too.
What to look for in a quote
- Proof of accreditation you can verify
- What hours they’ll be on site
- How VAT is shown on the quote
- Whether inaccessible sections are listed on the report
What affects the quote in South Hinksey
A fixed price needs a few facts first. We look at:
- Parking and loading at the site
- The condition of the system
- Whether it’s a one-off visit or part of a schedule
- Working hours and out-of-hours timing
What you pay reflects the actual work. That is why we survey first, from photos or on site, and the price is agreed before we start.
What we need to know
When you call or email, it’s useful to have:
- Problems your staff have spotted
- The postcode and the type of business
- Detail shots of panels, filters and grilles
- The paperwork from the last visit, if you have it
For a fixed quote, call 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.
Questions from South Hinksey
Can ventilation in schools around South Hinksey be cleaned out of term?
Yes, holiday work suits schools best. The FSA’s register shows about 39 schools and colleges with food registrations within roughly a mile and a half of South Hinksey. Tell us your holiday dates and we will book the visit for when the site is empty.
Will you come out to South Hinksey?
Yes, South Hinksey is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
What is TR19?
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.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
What information do you need?
A short description and a few pictures, with the address and opening hours. We will ask for anything else we need.
What do you clean inside the unit?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
Will you repair the fan or motor?
AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded for your maintenance team to follow up.
What a clean won’t put right
We will always give you a straight diagnosis, so here’s what this work can’t put right:
- Controls and BMS settings that run the unit
- Ductwork downstream of the unit, which is a separate clean
- A system that’s undersized for the building
If in doubt, call us on 0345 646 2711, or email photos and we will say what we think before you book.
