AHU cleaning in Arkley, done properly
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. Typical jobs include air handling units with blocked filters and debris and leaves in the fresh air intake, on drain trays, heating and cooling coils and filter sections.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. An inspection first shows where cleaning is needed in a building in Arkley.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

What else we do in Arkley
Managing agents and facilities teams in Arkley
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
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.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey so the quote reflects it.
The process
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes one overnight shift for many single units, with bigger plant phased. Getting kit into a London building takes planning, so let us know where we can load and park in Arkley.
- 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 pictures are taken and the certificate issued.
How to prepare
- Move anything stored near the system
- Mention any locked doors, roof access or ceiling voids
- Make sure someone can let us in and lock up afterwards

Advice
What affects the cost of AHU cleaning
Every site gets its own quote. This is what makes a difference:
- The size of the system
- The times the site is available
- What state the system is in
- How easy every part is to reach
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.
Asking for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Problems your staff have spotted
- The paperwork from the last visit, if you have it
- When the site is open and when it’s quiet
Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before we start.
Why act early in Arkley
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. London sites work long hours, and the longer a job is left, the bigger it gets.
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.

When something else is needed
In fairness, there are a few things this work will not fix:
- Damaged coils beyond cleaning
- Faulty motors, drives or bearings
- Airflow problems caused by the system’s design
If you are not sure, just call 0345 646 2711, or email photos and we will give you a straight answer.
Where we work
- Dampers and louvres
- Filter sections
- Internal panels
- Supply and extract fans
- Drain trays
- Heating and cooling coils
What staff can safely do
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
