Oxfordshire · Air handling unit cleaning
AHU Cleaning in Milton Hill
One call covers cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces in Milton Hill, from survey to sign-off. CHAS and SafeContractor accredited, ISO 9001 and fully insured.
- Dirty coils holding back the airflow
- Filters that are clogged or overdue
- Air handling units due a clean after building work
What we are called out for in Milton Hill
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and slime and smells soon follow.
Most sites get in touch after spotting one of these:
- Filters that are clogged or overdue
- Debris and leaves in the fresh air intake
- Drain trays holding standing water
- Plant that needs cleaning after a refit
If you run a surgery, dental practice or care home near Milton Hill, clean ventilation matters as much to you as to a hospital like Abingdon Community Hospital (about 3.9 miles north).

AHU cleaning for kitchens and businesses in Milton Hill
We clean air handling units for buildings in Milton Hill and across Oxfordshire, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you have dirty fans and fan housings and leaves and litter drawn into the unit, we can help.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

What staff can safely do
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.
Milton Hill questions
Will you come out to Milton Hill?
Yes, Milton Hill is part of our area, however small the site. A survey first, from photos or a visit, means we arrive with the right kit.
Do you work overnight in Milton Hill?
Yes, nights and weekends are routine for us. That way a site in Milton Hill doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
How long does an AHU clean take?
It takes anything from half a day for one small unit to several shifts for a plant room full of them. The unit’s size and condition make the biggest difference, and we will confirm the time when we quote.
How often do AHUs need cleaning?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and the report recommends a next date.
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 are fully insured.
What about areas you can’t get to?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Can you fix a faulty AHU?
The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.
Is there a report after cleaning?
Yes. You get a TR19® certificate plus before and after pictures. They’re worth keeping with the plant records.
How we price AHU cleaning
The survey tells us what the work involves. We look at:
- Site requirements such as sign-in and permits
- Where the site is and how we reach it
- How many systems or sites are involved
- The times the site is available
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before we start.
What we need to know
Photos and a few facts are often enough to price the work. Useful things to send:
- Wide photos of the system and the area around it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- When the site is open and when it’s quiet
- Any access panels or hatches you can see
To help us quote: the address, the type of site and when it’s open, a few pictures and any previous report or certificate. Then ring 0345 646 2711 or drop us a line.
How it works
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes from a few hours for a compact unit to a day or more for a large one. If you can send photos, we can arrive in Milton Hill knowing what to expect.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Getting ready for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Mention any sign-in, permit or induction we need
- Make sure someone can let us in and lock up afterwards
How to get a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Honest limits
We won’t sell you work that does not address the problem, so these are the things it will not cover:
- A system that is undersized for the building
- Ductwork downstream of the unit, which is a separate clean
- Problems with the unit’s controls or sensors
If you’re not sure, just phone us on 0345 646 2711 or email us and we’ll give you a straight answer.
What we work on in Milton Hill
- Supply and extract fans
- Internal panels

Why deal with it now?
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. Equipment tucked in a roof space or outbuilding near Milton Hill rarely gets looked at unless someone books it.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we will price it together.
