How we handle AHU cleaning in Whitton
If the units serving a building in Whitton 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. Typical jobs include air handling units due a clean after building work and air handling units never cleaned inside, across supply and extract fans, filter sections and internal panels.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. In Whitton, as elsewhere, cleaning starts with an inspection of what’s there.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Common problems we fix in Whitton
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and that is where slime and odours start.
The symptoms we are asked about most include:
- Intake sections clogged with outdoor debris
- Fan sections that haven’t been cleaned in years
- Dirty filters cutting the airflow
- Units needing a clean before a new tenant or handover
If you manage a school such as Royal Military School of Music, ventilation cleaning is best booked for the holidays.
Questions to ask before you book
- If the quote is a fixed price or an estimate
- Whether the quote is based on a survey or pictures
- When they can work, and whether that is outside your opening hours
- How VAT is shown on the quote
What affects the quote in Whitton
The price is fixed before any work begins. It’s based on:
- One-off work versus a regular cycle
- How many systems or sites are involved
- What state the system is in
- Parking and loading at the site
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.
What we need to know
There’s no need for technical detail. Just send:
- Wide photos of the system and the area around it
- Any previous report or certificate
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The site address and the type of premises
Here’s what helps us quote: where the site is, what it is and its opening hours, a few pictures and any previous report or certificate. Then give us a ring on 0345 646 2711, or send details by email.
Ventilation in Whitton buildings
There are about 22 schools, colleges and universities, about 33 care, childcare and hospital premises and about 3 hotels and B&Bs on the FSA’s food hygiene register across Whitton and its immediate surroundings (about a mile and a half). Buildings like these often rely on mechanical ventilation, which TR19® Air covers. The nearest hospital to Whitton is South Middlesex Hospital, about 0.8 miles north-east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first.
Healthcare buildings such as South Middlesex Hospital, about 0.8 miles north-east, depend on their ventilation; if you manage a surgery, clinic or care home near Whitton, yours matters too. Workplaces around Whitton station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.

Advice
Common questions in Whitton
Do you work at weekends in Whitton?
Yes, evening, overnight and weekend work is normal for us. The work in Whitton can fit around your hours. Let us know the hours you’re closed and we will book within them.
Can a school’s ventilation in Whitton be done out of term time?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 22 schools, colleges and universities with registered kitchens within about a mile and a half of Whitton. Booking early in the term gives the best choice of holiday dates.
How much notice do you need?
Earlier is better, particularly for night and weekend visits. We typically quote within one working day, and emergencies are covered by our 24/7 line.
Can you fix a faulty AHU?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report for your maintenance team to follow up.
How much does AHU cleaning cost in Whitton?
It depends on the site, so we quote each one individually. For a quote, call us on 0345 646 2711 or drop us a line and tell us about the site and its opening hours.
How long does it take to clean an air handling unit?
It takes half a day to a full day per unit, with large plant planned over several shifts. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
What information do you need?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then call 0345 646 2711 or drop us a line.
What does TR19 mean?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
In-house cleaning or a specialist?
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Why it’s worth doing now in Whitton
Tenants, auditors and owners may want proof that the air handling plant is kept clean. Our certificate and photo report give you clear evidence, ready to show anyone who asks. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.

Different parts, different methods
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
