AHU cleaning in Whitchurch-on-Thames
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. The work covers dampers and louvres, internal panels and filter sections, and common reasons people get in touch are odours coming through the supply air and filters that are clogged or overdue.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Good records are part of the job. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Fixed quotes for AHU cleaning in Whitchurch-on-Thames
The quote reflects the site in front of us. We take into account:
- The number of sites or systems
- Travel, parking and unloading
- One-off work versus a regular cycle
- How big the system is
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will explain each part.
Asking for a quote
There’s no need for technical detail. It helps if you can send:
- Photos showing the whole system and its surroundings
- The site address and the type of premises
- Any symptoms, from odd noises to smells or leaks
- The times we could work without disrupting the site
To get a fixed quote, give us a ring on 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. We normally come back within one working day.
Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.

What happens on the day
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes from a few hours for a compact unit to a day or more for a large one. In a small place like Whitchurch-on-Thames, the journey is planned ahead and the visit arranged around the site’s hours.
- We look at the unit and the plant area during the survey.
- 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.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Move anything stored near the system
- Find the previous report, if there is one
- Allow time for equipment near the work to be turned off and cool down

Signs you need AHU cleaning in Whitchurch-on-Thames
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. So a unit can be well maintained and still dirty.
Clients typically contact us after spotting something like this:
- Debris and leaves in the fresh air intake
- Units needing a clean before a new tenant or handover
- Condensate trays that will not empty
- Filters that are clogged or overdue
If you run an office near Pangbourne station, its supply ductwork can gather dust for years before anyone looks inside.
Questions to ask before booking
- When they can work, and whether that’s outside your opening hours
- Whether they recommend a next date
- Whether the price is fixed
- Which accreditations they hold, and whether you can check them

What else we do in Whitchurch-on-Thames
Between visits
Once we have finished, these simple steps help:
- Flag stale or damp smells in the supply air
- Make sure condensate is draining away
- Don’t store bins or materials near the intake
- Book the next check in line with the report
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
What AHU cleaning can’t fix
We’d rather tell you now than book work that will not help, so these are the things it will not cover:
- Ductwork downstream of the unit, which is a separate clean
- Faulty motors, drives or bearings
- Leaking heating or cooling coils
Not sure which it is? You can call us on 0345 646 2711 or drop us a line and we’ll tell you honestly before you book.
