AHU cleaning for kitchens and businesses in Bury Green
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. The work covers drain trays, supply and extract fans and internal panels, and common reasons people get in touch are rooms that smell stuffy when the system runs and condensate trays that won’t empty.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What the work involves, part by part
Drain trays
The drain tray collects water from the cooling coil. Standing water and slime are removed and the outlet is checked.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.

Managing agents and facilities teams in Bury Green
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
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.
The process
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. On site, the work takes from a few hours for a compact unit to a day or more for a large one. A few pictures of the system help us make the most of a visit to a place like Bury Green.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Before we arrive
- Name a contact who can let us in at the agreed time
- Mention any locked doors, roof access or ceiling voids
- Find the previous report, if there is one

Looking after it afterwards
So the system stays in good health:
- Change filters on schedule and log each change
- File each AHU report in the maintenance log
- Look at the condensate drain whenever the unit is serviced
- Watch for drips or damp patches near the plant
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
Signs you need AHU cleaning in Bury Green
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. So a unit can be well maintained and still dirty.
Clients typically contact us after spotting something like this:
- Dirty coils holding back the airflow
- Leaves and litter drawn into the unit
- Blocked condensate drains and slimy trays
- Air handling units due a clean after building work
Healthcare ventilation, from large hospitals like Herts and Essex Hospital (about 2.9 miles east) to small clinics, depends on clean filters, coils and ducts.
