AHU cleaning in South Acton, done properly
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. We look at the unit first, from pictures or a site visit, and send you a fixed quote before any cleaning starts. We are often asked to deal with blocked condensate drains and slimy trays and air handling units with blocked filters, on drain trays, dampers and louvres and filter sections.
Many London buildings have had their ventilation extended and altered through several fit-outs, leaving sections that are hard to reach and seldom cleaned. In South Acton, as elsewhere, cleaning starts with an inspection of what’s there.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What happens on the day
A visit follows the same order every time: protect the area, isolate whatever needs isolating, carry out the AHU cleaning, clear away and hand over the paperwork. The visit itself takes one overnight shift for many single units, with bigger plant phased. Managed blocks in London often need contractors booked in ahead, and we are happy to deal with the agent directly for a site in South Acton.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know about permits to work or site inductions
- Make sure someone can let us in and lock up afterwards
Ask for a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

Common questions in South Acton
How do you handle parking and loading in South Acton?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Night visits tend to make loading easier on London streets.
Can ventilation in schools around South Acton be cleaned out of term?
Yes, and it’s the easiest time to do it. With about 63 schools and colleges on the FSA’s register within roughly a mile and a half of South Acton, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
How do you keep the site clean during the work?
By covering it before any work starts. We keep the work contained and clean down when we finish.
What does AHU cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. We fix the price before any work starts.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Will you repair the fan or motor?
AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded so your maintenance contractor can deal with it.
Can you look after several sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Every site has its own report.
Can you clean the ducts connected to the AHU?
Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can quote for both.
What AHU cleaning cannot fix
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It will not put right:
- Faulty motors, drives or bearings
- Ventilation that was badly designed in the first place
- Damaged coils beyond cleaning
Not sure which it is? You can call us on 0345 646 2711 or email us and we’ll tell you honestly.
Parts of the system we cover
- Dampers and louvres
- Supply and extract fans
- Filter sections
- Drain trays
- Heating and cooling coils
- Internal panels
What the work involves, part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
Fixed quotes for AHU cleaning in South Acton
The survey tells us what the work involves. The main factors are:
- Whether several sites go on one quote
- What state the system is in
- Where the site is and how we reach it
- Any permits to work or inductions
We do not list prices on the website, because each job is priced on what it involves. For a fixed quote, give us a ring on 0345 646 2711 or send us an email, and we will talk you through it.
What to send for a quote
There’s no need for technical detail. Just send:
- Problems your staff have spotted
- Your last certificate, test record or report
- Your opening hours and when the area is out of use
- Close-ups of filters, grilles, hatches or access panels
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price, before work begins.
What happens if it’s left?
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, especially where there’s been moisture. Leaving it on a busy London site only adds to the work.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, call 0345 646 2711, or email photos for straight advice and a fixed quote.

Signs you need AHU cleaning in South Acton
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
Common reasons sites call us include:
- Air handling units due a clean after building work
- Filters that are clogged or overdue
- Dirty fans and fan housings
- Condensate trays that will not empty
Workplaces around South Acton station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
