What AHU cleaning looks like in Hounslow West
The FSA’s food hygiene register lists about 33 schools, colleges and universities, about 37 care, childcare and hospital premises and about 16 hotels and B&Bs with registered kitchens or food service within 1.5 miles or so of the middle of Hounslow West. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first. About 0.7 miles east of Hounslow West is Hounslow 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.

AHU cleaning in Hounslow West
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from photos or on site, followed by a fixed quote before any cleaning starts. The work covers dampers and louvres, heating and cooling coils and supply and extract fans, and the jobs we see most are stale or musty smells from the ventilation and intake sections clogged with outdoor debris.
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. For a building in Hounslow West, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.

Different parts, different methods
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. We clean the impeller, housing and surrounding section.
Signs you need AHU cleaning in Hounslow West
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 one of these:
- Debris and leaves in the fresh air intake
- Condensate trays that will not empty
- Plant that has been serviced but not cleaned
- Odours coming through the supply air
If you manage a school such as Hounslow Heath Infant and Nursery School, ventilation cleaning is best booked for the holidays.
Before you book anyone
- Proof of insurance
- If the quote is a fixed price or an estimate

For landlords and multi-site operators
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.

Why it’s worth doing now in Hounslow West
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. A building in Hounslow West may have flats or offices above and alongside, and a fault in the system can affect them too.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will explain each part.
