Greater London · Air handling unit cleaning
Air handling unit cleaning in Eastbury, Greater London
AHU cleaning for businesses, landlords and public buildings in Eastbury. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- Plant that needs cleaning after a refit
- Units that have only ever had filter changes
- Dust-coated heating and cooling coils
How it works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes from a few hours for a compact unit to a day or more for a large one. Most London sites can’t stop for the day, so work in Eastbury is typically done overnight, early in the morning or at weekends.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Preparing for the visit
- Let us know about permits to work or site inductions
- Clear the space around the work
- Make sure equipment near the work can be switched off and left to cool
How to get a quote
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Advice
AHU cleaning in Eastbury
Our AHU cleans for sites in Eastbury cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. The work covers supply and extract fans, heating and cooling coils and drain trays, and common reasons people get in touch are dust-coated heating and cooling coils and plant that has been serviced but not cleaned.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Eastbury, dust settles in the units and ducts year after year.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

AHU cleaning in Eastbury: local notes
There are about 28 schools, colleges and universities and about 27 caring premises (care homes, nurseries and hospitals) on the FSA’s food hygiene register in and around Eastbury, up to about a mile and a half out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. The nearest hospital to Eastbury is Northwood and Pinner Cottage Hospital, about 1.2 miles south. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. Getting kit to a London plant room usually means lifts, stairs and an agreed loading slot.
If you manage a school such as Eastbury Farm Primary School, ventilation cleaning is best booked for the holidays.
Eastbury is about 3 miles south-east of Rickmansworth, in Greater London.

In-house cleaning or a specialist?
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Eastbury: your questions answered
Can you work in Eastbury outside opening hours?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Eastbury needn’t be disturbed. Just ring 0345 646 2711, or send details by email with your opening times and we will plan around them.
Can a school’s ventilation in Eastbury be done out of term time?
Yes, out-of-term visits are normal for schools. There are about 28 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Eastbury. Tell us your holiday dates and we will book the visit for when the site is empty.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Call us any time and explain what’s happened.
Can you clean the ducts connected to the AHU?
Yes, the ductwork, grilles and diffusers the unit serves. We’ll tell you after the survey whether the ducts need it.
Is there a report after cleaning?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
Is a quote from photos possible?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
Can you look after several sites?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
Will you repair the fan or motor?
Our AHU work is cleaning rather than mechanical repair. Any faults we notice are recorded so your maintenance contractor can deal with it.
Part by part
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with pictures.
Common problems we fix in Eastbury
Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
These are the problems we see most often:
- Dirty fans and fan housings
- Air handling units due a clean after building work
- Intake sections clogged with outdoor debris
- Air handling units with blocked filters
Healthcare ventilation, from large hospitals like Northwood and Pinner Cottage Hospital (about 1.2 miles south) to small clinics, depends on clean filters, coils and ducts.

How we price AHU cleaning
Before we fix a price, we need to know a few things. We look at:
- Access, including roofs, risers and ceiling voids
- Parking and loading at the site
- The times the site is available
- How many systems or sites are involved
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.
What to send for a quote
There’s no need for technical detail. It helps if you can send:
- Wide photos of the system and the area around it
- The times we could work without disrupting the site
- Problems your staff have spotted
- The roof, plant room or outside wall the system runs to
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before any work starts.
Managing agents and facilities teams in Eastbury
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
What AHU cleaning cannot fix
It’s worth knowing the limits before booking:
- The supply and extract ducts, quoted separately
- Airflow problems caused by the system’s design
- Leaking heating or cooling coils
Not sure which it is? You can phone us on 0345 646 2711 or send us an email and we will tell you honestly.
