AHU cleaning in Shepperton, done properly
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. The work covers supply and extract fans, heating and cooling coils and dampers and louvres, and the jobs we see most are plant that needs cleaning after a refit and leaves and litter drawn into the unit.
In a place like Shepperton, air handling units are often tucked into roof spaces or small plant rooms, out of sight and easy to overlook. Filters, coils and drain trays need attention whatever the size of the unit.
The paperwork matters as much as the work. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Between visits
Think of this as the after-treatment advice, in brief:
- Look at the condensate drain whenever the unit is serviced
- Watch for drips or damp patches near the plant
- Diary the inspection date recommended in the report
- Report musty smells from the vents straight away
Stick to the filter change schedule, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
How the job changes from site to site
Drain trays
Older trays can corrode and start leaking. Their condition goes into the report with pictures so you can decide on any repairs.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. Access is planned during the survey so the quote reflects it.
How it works
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. For a place like Shepperton, we load the van from the survey notes so the work can be done in one visit where possible.
- 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
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us about site rules, permits or sign-in
- Let us know when the site is closed or quiet

Shepperton: your questions answered
Can you clean school ventilation in Shepperton during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Shepperton, the Food Standards Agency lists about 10 schools and colleges with registered kitchens within a mile and a half or so. Just call 0345 646 2711 or email us with your term dates and we’ll plan around them.
Do you work in villages like Shepperton?
Yes. Villages and rural sites across the South East are part of our work, Shepperton included. Let us know about access, parking and anything unusual about getting there when you book.
What happens if you cannot reach some of it?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
What does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we will usually reply within one working day.
When should our AHU next be cleaned?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and the report recommends a next date.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
How long does it take to clean an air handling unit?
Expect it to take anything from half a day for one small unit to several shifts for a plant room full of them. Size, layout and how dirty it is decide the rest, and we will confirm the time when we quote.
What information do you need?
Where the site is, what it is and when it’s open, plus pictures of the system and your last certificate or report if you have one.
What staff can safely do
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Common problems we fix in Shepperton
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.
Most sites get in touch when they notice something like this:
- Units needing a clean before a new tenant or handover
- Blocked condensate drains and slimy trays
- Filters that are clogged or overdue
- Debris and leaves in the fresh air intake
For schools like Thamesmead School, the holidays are the usual time to inspect and clean ventilation.
