Air handling unit cleaning in Molash, Kent
Professional AHU cleaning in and around Molash, timed so the site keeps working and finished with a written report and photos.
- Plant that needs cleaning after a refit
- Condensate trays that won’t empty
- Plant that has been serviced but not cleaned
The process
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes from a few hours for a compact unit to a day or more for a large one. If the van will struggle with a lane or gateway near Molash, let us know and we will plan around it.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Mention any parking or loading restrictions
- Make sure someone can let us in and lock up afterwards

About our AHU cleaning in Molash
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. We are often asked to deal with dirty fans and fan housings and plant that needs cleaning after a refit, across heating and cooling coils, dampers and louvres and supply and extract fans.
For a building in or near Molash, 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: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

- Which accreditations they hold, and whether you can check them
- What happens if part of the system cannot be accessed
Looking after it afterwards
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Clear leaves and litter away from the intake
- Look at the condensate drain whenever the unit is serviced
- Watch for drips or damp patches near the plant
- Keep inspection doors on the unit in good order
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to confirm water is draining away.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
Why it’s worth doing now in Molash
Standing water in a drain tray does not clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. With notice, the visit to Molash can be fitted around your bookings and events.
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before we start.

Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Every site has its own report.
How the job changes from site to site
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
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.
What your team can do, and what needs us
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.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
