AHU cleaning in Bow Brickhill, done properly
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. The work covers supply and extract fans, drain trays and heating and cooling coils, and people most often call us about stale or musty smells from the ventilation and leaves and litter drawn into the unit.
In a village or hamlet like Bow Brickhill, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Leave it or put it right?
Dirt left in an air handling unit does not stay in the unit. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. A planned visit to Bow Brickhill is easier to arrange than an emergency callout.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote, and the price is fixed before work begins.
Why book with us
- Work around your opening hours, with 24/7 emergency cover
- Full insurance on every job
- One number for every site across the South East and London
- Fixed quotes from a survey or pictures
How it works
Everything the job needs comes with us, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Rural roads and tight entrances are worth telling us about before a visit to Bow Brickhill.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after photos.
Getting ready for the visit
- Clear the space around the work
- Arrange a key holder or contact on site
- Tell us where we can park and unload

Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- File each AHU report in the maintenance log
- Keep inspection doors on the unit in good order
- Stick to the filter change plan
- Report water on the plant room floor
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.

Your questions about AHU cleaning in Bow Brickhill
Can you get to a site in Bow Brickhill?
Yes. Bow Brickhill is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Can ventilation in schools around Bow Brickhill be cleaned out of term?
Yes, out-of-term visits are normal for schools. With about 5 schools and colleges on the FSA’s register within roughly a mile and a half of Bow Brickhill, it pays to plan holiday dates ahead. You can give us a ring on 0345 646 2711 or drop us a line with the dates the site is empty.
How often do AHUs need cleaning?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and we’ll suggest an interval after the first clean.
Do you clean the ductwork as well?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can quote for both.
What do you clean inside the unit?
Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.
Can you clean the AHU out of hours?
Yes. We work evenings, overnight and weekends, so offices, schools and shops can carry on.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
How much does AHU cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before any work starts.
Multi-site and managed buildings
From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
We also work for facilities teams across offices, schools and healthcare across Milton Keynes. Larger estates can be phased building by building to keep disruption down.
What we’re called out for in Bow Brickhill
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and that’s where slime and odours start.
Most sites get in touch when they notice something like this:
- Air handling units due a clean after building work
- Drain trays holding standing water
- Dirty fans and fan housings
- Air handling units never cleaned inside
If you run a surgery, dental practice or care home near Bow Brickhill, clean ventilation matters as much to you as to a hospital like Bletchley Community Hospital (about 2.9 miles west).
What to look for in a quote
- Which accreditations they hold, and whether you can check them
- Whether the work can be done while the site is closed
- How areas they can’t reach will be recorded
- When the next visit should be, and why
How the job changes from site to site
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Drain trays
The drain tray collects water from the cooling coil. Standing water and slime are removed and the outlet is checked.
