- Controls and BMS settings that run the unit
- Mechanical faults with motors, belts or bearings
- Dirty ducts beyond the unit itself

How we handle AHU cleaning in Eight Ash Green
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. If you have dust built up on fan impellers and odours coming through the supply air, we can help, from dampers and louvres, heating and cooling coils and supply and extract fans onwards.
Somewhere as small as Eight Ash Green, ducted ventilation is usually 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.
A written report with pictures follows each visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What affects the cost of AHU cleaning
You’ll get a fixed price before any work starts. It takes into account:
- The times the site is available
- Whether we need access equipment or extra panels
- Whether it’s a one-off visit or part of a schedule
- The scale of the work
You will not find a price list here, because each job is priced on what it involves. For a fixed quote, call 0345 646 2711 or drop us a line, and we’ll explain what it covers.
Helping us quote
A few details help us quote accurately. When you get in touch, it helps to send:
- How we’d reach plant on a roof or in a plant room
- Problems your staff have spotted
- Photos showing the whole system and its surroundings
- The paperwork from the last visit, if you have it
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

What the work involves, part by part
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and clean the filter housing.

Advice
Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Keep the certificate and photo report with the plant records
- Look at the condensate drain whenever the unit is serviced
- Watch for drips or damp patches near the plant
- Keep the area around the fresh air intake clear
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.

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.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
