About our AHU cleaning in Milland
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. We’re often asked to deal with plant that has been serviced but not cleaned and leaves and litter drawn into the unit, on dampers and louvres, drain trays and filter sections.
For a building in or near Milland, access is agreed in advance and the visit is planned around the journey.
Duct Doctor has been trading since 2009, as 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.

In-house cleaning or a specialist?
When your team notices a problem 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.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
When something else is needed
In fairness, some problems need a different fix:
- Problems with the unit’s controls or sensors
- Ductwork downstream of the unit, which is a separate clean
- A system that’s undersized for the building
If you’re not sure, just phone us on 0345 646 2711, or email photos and we will give you a straight answer.
What we work on in Milland
- Dampers and louvres
- Heating and cooling coils
- Filter sections
- Drain trays
- Internal panels
- Supply and extract fans
Common problems we fix in Milland
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
The symptoms we’re asked about most are:
- Plant that needs cleaning after a refit
- Fan sections that haven’t been cleaned in years
- Dirty filters cutting the airflow
- Air handling units never cleaned inside
School buildings such as Hollycombe Primary School are usually done in the holidays, so classrooms aren’t disturbed.
Questions to ask before booking
- If the quote is a fixed price or an estimate
- Whether inaccessible sections are listed on the report
- Proof of insurance
- Whether the quote is based on a survey or photos
Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
Milland questions
Can ventilation in schools around Milland be cleaned out of term?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Milland. Tell us your holiday dates and we will book the visit for when the site is empty.
Can the work in Milland be done at night or at weekends?
Yes, we can come after you close and finish before you open. The work in Milland can fit around your hours. Your opening times are the first thing we ask for.
Is Milland in your area?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Milland.
What should I send you?
Where the site is, what it is and when it’s open, plus pictures of the system and your last certificate or report if you have one.
What’s included in an AHU clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. We confirm the scope after looking at the unit.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. We keep the work contained and clean down when we finish.
Can you set up regular visits?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed 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. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
Fixed quotes for AHU cleaning in Milland
Sites vary more than people expect. The main factors:
- Where the site is and how we reach it
- The times the site is available
- Whether it’s a one-off visit or part of a schedule
- How big the system is
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before we start.
What to send for a quote
We can often survey from photos. Try to include:
- Photos showing the whole system and its surroundings
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The paperwork from the last visit, if you have it
- Any access panels or hatches you can see
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 we can price many jobs without a visit.
Aftercare tips
Good habits slow the build-up between visits. A few tips:
- Diary the inspection date recommended in the report
- Report stiff or damaged access doors
- Don’t ignore odours coming through the grilles
- Keep filter changes on time and recorded
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.
Keep the area around the intake clear. What’s near the intake ends up in the unit.

- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
