About our AHU cleaning in Walham Green
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. If you have blocked condensate drains and slimy trays and rooms that smell stuffy when the system runs, we can help.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. In a building in Walham Green, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.
Think of the report as the system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Part by part
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
What AHU cleaning can’t fix
A few issues sit outside what this work can do:
- Ventilation that was badly designed in the first place
- Controls and BMS settings that run the unit
- Damaged coils beyond cleaning
If you’re not sure, just call us on 0345 646 2711 or drop us a line and we’ll give you a straight answer before booking.
Parts of the system we cover

The process
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes half a day to a full day per unit, with large plant planned over several shifts. We fit London jobs around the building rather than the other way round, so a visit in Walham Green is usually out of hours.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Clear loose items from the work area
- Mention any sign-in, permit or induction we need
- Let us know about parking and loading
Ask for a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and the last certificate or report, if there is one. Then give us a ring on 0345 646 2711, or email photos.
Advice
When to call us in Walham Green
Whatever surrounds a building in Walham Green, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
Keep an eye out for these warning signs:
- Odours coming through the supply air
- Air handling units with blocked filters
- Air handling units due a clean after building work
- Fan sections that haven’t been cleaned in years
Healthcare buildings such as Chelsea and Westminster Hospital, about 0.5 miles north-east, depend on their ventilation; if you manage a surgery, clinic or care home near Walham Green, yours matters too.
What to look for in a quote
- Whether a survey comes first
- How VAT is shown on the quote
- Exactly which parts of the system are covered
- When they can work, and whether that’s outside your opening hours
Looking after it afterwards
Aftercare is simple, and it helps at the next visit:
- Do not store bins or materials near the intake
- Do not ignore odours coming through the grilles
- Store the TR19 paperwork where auditors can find it
- Report water on the plant room floor
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
Walham Green questions
What do you need to know about parking in Walham Green?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. If the building has a loading slot system, we will book into it.
Do you work overnight in Walham Green?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Walham Green needn’t be disturbed. Your opening times are the first thing we ask for.
Will we get paperwork for the AHU clean?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
When should our AHU next be cleaned?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and we’ll suggest an interval after the first clean.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
Can you fix a faulty AHU?
AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded so your maintenance contractor can deal with it.
What about areas you cannot get to?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Which kinds of sites do you work on?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.

Why it’s worth doing now in Walham Green
Standing water in a drain tray does not clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. London sites work long hours, and the longer a job is left, the bigger it gets.
The cost depends on the size of the system, the condition it’s in and access to every part of it. We give you a fixed price before we start, so there are no surprises.

In-house cleaning or a specialist?
Logging matters as much as cleaning. 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.
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.
Ventilation in Walham Green buildings
Food Standards Agency data includes about 59 schools, colleges and universities, about 74 hospitals, care homes and childcare premises and about 47 hotels and B&Bs in and around Walham Green, up to about a mile and a half out. Busy, occupied buildings like these are where clean supply air matters most. Getting kit to a London plant room usually means lifts, stairs and an agreed loading slot. For Walham Green, the closest hospital is Chelsea and Westminster Hospital, roughly 0.5 miles north-east. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
School buildings such as Chelsea Independent College are usually done in the holidays, so classrooms are not disturbed. Workplaces around Imperial Wharf station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
