AHU cleaning in Roundbush Green, done properly
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. If you are dealing with fan sections that haven’t been cleaned in years and intake sections clogged with outdoor debris, we can help, from dampers and louvres, drain trays and internal panels onwards.
For a building in or near Roundbush Green, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
The report is your system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

When something else is needed
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:
- Mechanical faults with motors, belts or bearings
- Controls and BMS settings that run the unit
- Leaking heating or cooling coils
If in doubt, ring 0345 646 2711 or send us an email and we will say what we think.

- Heating and cooling coils

When to call us in Roundbush Green
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Roundbush Green, that’s air they breathe for hours at a time.
These are the problems we see most often:
- Leaves and litter drawn into the unit
- Dirty fans and fan housings
- Filters that are clogged or overdue
- Blocked condensate drains and slimy trays
Classrooms and halls at schools such as Rodings Primary School are easiest to work in when pupils are away.

What affects the cost of AHU cleaning
We quote each job individually. These are the things that affect it:
- Whether it’s a one-off visit or part of a schedule
- Any permits to work or inductions
- Access, including roofs, risers and ceiling voids
- How many systems or sites are involved
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before work begins, so you know where you stand.
What we need to know
Photos let us diagnose from a distance. Try to include:
- A few general shots of the system
- The times we could work without disrupting the site
- The roof, plant room or outside wall the system runs to
- Any previous report or certificate
Getting a quote does not take long. Call or email with a few details and you will usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
What we do, step by step
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. From there, it takes anything from half a day for one small unit to several shifts for a plant room full of them. A quick note on how to find the site and where to park makes a visit to Roundbush Green run smoothly.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare

Advice
How the job changes from site to site
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
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.
Aftercare tips
Once we have finished, these simple steps help:
- Look at the condensate drain whenever the unit is serviced
- Don’t store bins or materials near the intake
- File each AHU report in the maintenance log
- Diary the inspection date recommended in the report
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Keep the area around the intake clear. What’s near the intake ends up in the unit.

Staff cleaning versus specialist work
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
