About our AHU cleaning in Kingston upon Thames
We clean air handling units for buildings in Kingston upon Thames and across Greater London, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. The work covers filter sections, drain trays and dampers and louvres, and the jobs we see most are leaves and litter drawn into the unit and coils clogged with dust and debris.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. An inspection first shows where cleaning is needed in a building in Kingston upon Thames.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Kingston upon Thames buildings and their air
There are about 40 schools, colleges and universities, about 33 care, childcare and hospital premises and about 7 hotels and B&Bs on the FSA’s food hygiene register in Kingston upon Thames and the streets around it, up to about 1.5 miles out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first. Kingston upon Thames’s nearest hospital, Kingston Hospital, is about 0.7 miles east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Kingston Hospital, about 0.7 miles east, is the nearest hospital to Kingston upon Thames, and healthcare sites of every size need their supply air kept clean. For schools like St Luke's CofE Primary School, the holidays are the usual time to inspect and clean ventilation.

What we do, step by step
Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. We fit London jobs around the building rather than the other way round, so a visit in Kingston upon Thames is typically out of hours.
- 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.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Name a contact who can let us in at the agreed time
- Mention any locked doors, roof access or ceiling voids
- Dig out any earlier paperwork for the system
How to get a quote
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before work begins.

Kingston upon Thames: your questions answered
Do you clean school ventilation in Kingston upon Thames in the holidays?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 40 schools, colleges and universities with registered kitchens within about a mile and a half of Kingston upon Thames. Booking early in the term gives the best choice of holiday dates.
Does London parking affect a job in Kingston upon Thames?
London parking can be tight, so details of loading bays and permits help. Working overnight, as we often do in London, normally makes it simpler.
What information do you need?
Some photos and a quick description of the system, with the address and opening hours. If we need more, we’ll ask.
What’s included in an AHU clean?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
How far ahead should we book?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
What about areas you cannot get to?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
Do you need to switch the unit off?
Yes, while the clean is under way. We can work evenings, overnight or at weekends to keep disruption down.
What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Looking after it afterwards
So the system stays in good health:
- Report stiff or damaged access doors
- Book the next check in line with the report
- Keep the certificate and photo report with the plant records
- Stick to the filter change plan
When we’ve closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
Leave it or put it right?
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, ready to show anyone who asks. A building in Kingston upon Thames may have flats or offices above and alongside, and a fault in the system can affect them too.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before we start.

What we are called out for in Kingston upon Thames
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
Signs it’s time to call us include:
- Plant that has been serviced but not cleaned
- Blocked condensate drains and slimy trays
- Units needing a clean before a new tenant or handover
- Rooms that smell stuffy when the system runs
Workplaces around Kingston station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.

- Whether they recommend a next date
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether the quote shows VAT
