Air handling unit cleaning in Knave's Ash, Kent
AHU cleaning for Knave's Ash, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.

When to call us in Knave's Ash
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and some travels further into the unit.
Common reasons sites call us are:
- Plant that has been serviced but not cleaned
- Rooms that smell stuffy when the system runs
- Drain trays holding standing water
- Dirty coils holding back the airflow
For schools like Hoath Primary School, the holidays are the usual time to inspect and clean ventilation.
Before you book anyone

AHU cleaning in Knave's Ash
Our AHU cleans for sites in Knave's Ash cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. If you are dealing with coils clogged with dust and debris and leaves and litter drawn into the unit, we can put it right, from supply and extract fans, dampers and louvres and internal panels onwards.
Somewhere as small as Knave's Ash, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Every visit ends with a written report and photos, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Why act early in Knave's Ash
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that doesn’t feel as comfortable, and a planned clean is far less disruptive than a breakdown. It’s worth booking a check, because nobody sees inside a duct day to day.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, call us on 0345 646 2711 or drop us a line for straight advice and a fixed quote.

AHU cleaning in Knave's Ash: local notes

Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. At about 55 miles from central London, Knave's Ash sits well inside the area we cover. We work evenings, overnight and at weekends, so the visit fits around the site. Knave's Ash’s nearest hospital, St Martins Hospital, is about 4.4 miles south-west. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.

What the work involves, part by part
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
Fans and fan sections
Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.
Looking after it afterwards
So the system stays in good health:
- Plan the next inspection before the last report gets filed away
- Report water on the plant room floor
- Report stiff or damaged access doors
- Keep the area around the fresh air intake clear
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
What your team can do, and what needs us
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. That part needs specialist access and equipment.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
