About our AHU cleaning in Shenley
If the units serving a building in Shenley have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. If you have intake sections clogged with outdoor debris and blocked condensate drains and slimy trays, we can help, from filter sections, heating and cooling coils and dampers and louvres onwards.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Good records are part of the job. Each visit is written up with pictures, 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 ready for an insurer, fire officer or EHO.

AHU cleaning around Shenley
Food Standards Agency data includes about 16 schools, colleges and universities and about 24 hospitals, care homes and childcare premises within about 1.5 miles of central Shenley. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Shenley is about 47 miles from central London, well within the area we cover across London and the South East. The visit is fixed around your opening hours, not ours. Shenley’s nearest hospital, Bletchley Community Hospital, is about 2.6 miles south-east. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
If you run a surgery, dental practice or care home near Shenley, clean ventilation matters as much to you as to a hospital like Bletchley Community Hospital (about 2.6 miles south-east). If you manage a school such as Christ the Sower Ecumenical Primary School (VA), ventilation cleaning is best booked for the holidays.

Different parts, different methods
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
Drain trays
Drain trays can rust and leak over time. We record their condition with pictures so repairs can be planned.
When it’s something else
It’s worth knowing the limits before booking:
- Coils that are corroded or leaking and need replacing
- Mechanical faults with motors, belts or bearings
- Ventilation that was badly designed in the first place
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we will tell you honestly.

How it works
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes one overnight shift for many single units, with bigger plant phased, and the area is cleaned down before we leave. If you can send pictures, we can arrive in Shenley knowing what to expect.
- We survey the unit from pictures or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Mention any sign-in, permit or induction we need
- Clear the space around the work

Advice
In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We will take a look and give you a fixed quote.
Keeping the system healthy
To keep the system working properly between visits:
- Report water on the plant room floor
- Check the drain tray is emptying during routine visits
- Report musty smells from the vents right away
- Make sure the unit’s access doors open easily
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
