Different parts, different methods
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
AHU cleaning in West Mersea
Our AHU cleans for sites in West Mersea 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. If you are dealing with drain trays holding standing water and fan sections that haven’t been cleaned in years, we can help.
In a place like West Mersea, air handling units are often tucked into roof spaces or small plant rooms, out of sight and easy to overlook. Filters, coils and drain trays need attention whatever the size of the unit.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What else we do in West Mersea
What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
When it’s something else
Some problems need a different service or another trade:
- The supply and extract ducts, quoted separately
- Breakdowns that need a mechanical engineer
- Problems with the unit’s controls or sensors
If you’re not sure, just ring 0345 646 2711, or send details by email and we’ll give you a straight answer before you book.

Keeping the system healthy
Aftercare is simple, and it helps at the next visit:
- Make sure condensate is draining away
- Report water on the plant room floor
- Keep inspection doors on the unit in good order
- File each AHU report in the maintenance log
Stick to the filter change schedule, 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.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
