About our AHU cleaning in Onslow Village
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. The work covers filter sections, internal panels and drain trays, and people most often call us about intake sections clogged with outdoor debris and dirty filters cutting the airflow.
Around a place like Onslow Village, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Even a small system collects dust in its ducts and filters.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What we work on in Onslow Village
- Filter sections
- Drain trays
- Internal panels
- Heating and cooling coils
- Dampers and louvres
- Supply and extract fans
What the work involves, part by part
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that will not bend or flatten the fins.
Drain trays
Older trays can corrode and start leaking. Their condition goes into the report with pictures so repairs can be planned.

Common problems we fix in Onslow Village
Air handling units are typically tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.
These are the problems we see most often:
- Drain trays holding standing water
- Odours coming through the supply air
- Intake sections clogged with outdoor debris
- Dust built up on fan impellers
Wherever a school like Onslow Infant School has ducted ventilation, a half-term visit keeps the work out of lesson time.

What affects the quote in Onslow Village
You’ll get a fixed price before any work starts. It takes into account:
- Site requirements such as sign-in and permits
- How big the system is
- One-off work versus a regular cycle
- The condition we find in the survey
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, give us a ring on 0345 646 2711, or send details by email and we’ll give you an honest view and a fixed quote.
What we need to know
You don’t need the technical terms. It helps if you can send:
- Wide pictures of the system and the area around it
- Your last certificate, test record or report
- Problems your staff have spotted
- The postcode and the type of business

- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Plan for cooking equipment or plant to be off before we arrive
- Clear loose items from the work area
Getting a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
