AHU cleaning in Sepham Heath, done properly
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 internal panels, drain trays and heating and cooling coils, and common reasons people get in touch are filters that are clogged or overdue and air handling units due a clean after building work.
In a village or hamlet like Sepham Heath, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
The sign-off is always in writing: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

What the work involves, part by part
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, before we quote.
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.

Managing agents and facilities teams in Sepham Heath
Facilities teams in offices, schools and healthcare sites book us too across Kent. Work can be phased by floor, building or site to keep disruption down.
Records are where multi-site compliance often slips. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- File each AHU report in the maintenance log
- Report water on the plant room floor
- Plan the next inspection before the last report gets filed away
- Keep inspection doors on the unit in good order
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.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
What AHU cleaning cannot fix
We won’t sell you work that doesn’t address the problem, so here are the limits:
- Controls and BMS settings that run the unit
- Leaking heating or cooling coils
- Faulty motors, drives or bearings
If you are not sure, just ring 0345 646 2711 or email us and we will give you a straight answer.
What the work covers
- Supply and extract fans
- Heating and cooling coils
- Internal panels
- Filter sections
- Dampers and louvres

What happens on the day
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes from a few hours for a compact unit to a day or more for a large one. Rural roads and tight entrances are worth telling us about before a visit to Sepham Heath.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Let us know about permits to work or site inductions
- Let us know how we reach the system, including roofs, risers and plant rooms

Leave it or put it right?
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. Rural sites cannot always move to another kitchen or room when something fails.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before any work starts.
