About our AHU cleaning in Marden
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, so cleaning the unit matters as much as cleaning the ducts. If you have plant that has been serviced but not cleaned and drain trays holding standing water, we can help.
In a place like Marden, 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.
The paperwork matters as much as the work. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

How it works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes half a day to a full day per unit, with large plant planned over several shifts. Getting to the system matters more than parking in a place like Marden, so let us know how to reach it.
- We survey the unit from pictures or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Find the previous report, if there is one
- Tell us where we can park and unload

Different parts, different methods
Internal casing and panels
We open each section through its doors and close them securely when we are done before the unit is handed back.
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.

When it’s something else
To be straight with you, there are a few things this work will not fix:
- Faulty motors, drives or bearings
- Coils that are corroded or leaking and need replacing
- Dirty ducts beyond the unit itself
If in doubt, phone us on 0345 646 2711 or drop us a line and we will say what we think before booking.
What we work on in Marden
- Supply and extract fans
- Dampers and louvres
- Heating and cooling coils
- Internal panels
- Filter sections
- Drain trays
What we’re called out for in Marden
Filters that are not changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
If you notice any of these, it’s worth a diagnosis:
- Debris and leaves in the fresh air intake
- Air handling units never cleaned inside
- Air handling units with blocked filters
- Fan sections that haven’t been cleaned in years
For schools like Marden Primary School, the holidays are the usual time to inspect and clean ventilation.
Comparing quotes
- What insurance they carry
- If the quote is a fixed price or an estimate
- Whether they recommend a next date
- What happens if part of the system can’t be accessed
Looking after it afterwards
To keep the system working properly between visits:
- Keep the area around the fresh air intake clear
- Watch for drips or damp patches near the plant
- Keep inspection doors on the unit in good order
- Stick to the filter change plan
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. Keep both with the building’s maintenance records.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
Questions from Marden
Do you clean school ventilation in Marden in the holidays?
Yes. The holidays are the usual time for school work. There are about 3 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Marden. You can call us on 0345 646 2711 or use the quote form with the dates the site is empty.
Do you cover smaller places like Marden?
Yes. Villages and rural sites across the South East are part of our work, Marden included. Let us know about access, parking and anything unusual about getting there when you book.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
How long does an AHU clean take?
Typically the clean takes one overnight shift for many single units, with bigger plant phased. We plan the shutdown around that, out of hours if needed.
Do you need to switch the unit off?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
Do you work evenings or weekends?
Yes, wherever it helps the building. Tell us when the unit can go off and we’ll work to that.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, and any sections we cannot reach are noted in the report, and new panels can be fitted.
Do you have a 24/7 line?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
What else we do in Marden
Why deal with it now?
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. Around Marden, a kitchen or building out of action is missed straight away.

In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
