About our AHU cleaning in Milton Heights
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. We are often asked to deal with units needing a clean before a new tenant or handover and odours coming through the supply air, on filter sections, supply and extract fans and internal panels.
For a building in or near Milton Heights, 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.
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.

What AHU cleaning cannot fix
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- Breakdowns that need a mechanical engineer
- Airflow problems caused by the system’s design
- Leaking heating or cooling coils
Not sure which it is? You can call us on 0345 646 2711 or email us and we’ll tell you honestly before you book.

How we price AHU cleaning
We quote each job individually. This is what makes a difference:
- How big the system is
- The number of sites or systems
- One-off work versus a regular cycle
- Any permits to work or inductions
What you pay reflects the actual work. That is why we survey first, from photos or on site, and why the quote is fixed before any work starts.
What to send for a quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- Any access panels or hatches you can see
- When the site is open and when it’s quiet
- Where the site is and what kind of site it is
- The roof, plant room or outside wall the system runs to

How it works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes one overnight shift for many single units, with bigger plant phased. For a village or hamlet like Milton Heights, tell us about narrow lanes, gates and parking when you book.
- The survey covers the unit, its access and how it can be shut down.
- 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.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Plan for cooking equipment or plant to be off before we arrive
- Mention any sign-in, permit or induction we need
- Let us know when the site is closed or quiet
Ask for a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Advice
Common problems we fix in Milton Heights
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
Signs it’s time to call us include:
- Units needing a clean before a new tenant or handover
- Condensate trays that won’t empty
- Leaves and litter drawn into the unit
- Dirty filters cutting the airflow
School buildings such as St Blaise CofE Primary School are normally done in the holidays, so classrooms aren’t disturbed.

What’s TR19?

How do you protect the area?

Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and you will get one fixed quote.
Why deal with it now?
Standing water in a drain tray doesn’t clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. Out of sight is the usual reason a rural system goes too long without attention.
What you pay depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before any work starts, so you know where you stand.
What you get with us
- One contact for all your sites in London and the South East

Between visits
Looking after the system between visits is straightforward, and it helps at the next visit:
- Make sure condensate is draining away
- Report musty smells from the vents straight away
- Keep the certificate and photo report with the plant records
- Diary the inspection date recommended in the report
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
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 send the paperwork to whoever needs it.
From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
