How the job changes from site to site
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
AHU cleaning in Well End, done properly
A cooling coil drips condensate into a tray that should drain away. 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 drain trays, supply and extract fans and internal panels, and people most often call us about plant that needs cleaning after a refit and blocked condensate drains and slimy trays.
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. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Aftercare tips
Once we’ve finished, these simple steps help:
- Keep filter changes on time and recorded
- Keep inspection doors on the unit in good order
- Report water on the plant room floor
- Don’t ignore odours coming through the grilles
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
What happens on the day
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, and the sign-off is a written report with pictures. Most of the time goes on the work itself, and that takes half a day to a full day per unit, with large plant planned over several shifts. In a small place like Well End, the journey is planned ahead and the visit arranged around the site’s hours.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Agree a time when the area can be out of use
- Make sure equipment near the work can be switched off and left to cool
- Mention any parking or loading restrictions

Why it’s worth doing now in Well End
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Well End simpler. Equipment tucked in a roof space or outbuilding near Well End rarely gets looked at unless someone books it.
The cost depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before we start, so there are no surprises.

What your team can do, and what needs us
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
What AHU cleaning looks like in Well End
There are about 7 schools, colleges and universities and about 13 caring premises (care homes, nurseries and hospitals) on the FSA’s food hygiene register across Well End and its immediate surroundings (about a mile and a half). Where buildings like these have air handling units, filters, coils and drain trays need regular attention. About 2.4 miles west of Well End is Marlow Community Hospital, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. We cover Well End, about 27 miles from central London, as part of our work across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you.
If you run an office near Bourne End station, its supply ductwork can gather dust for years before anyone looks inside. If you run a surgery, dental practice or care home near Well End, clean ventilation matters as much to you as to a hospital like Marlow Community Hospital (about 2.4 miles west). For schools like Claytons Primary School, the holidays are the usual time to inspect and clean ventilation.
