About our AHU cleaning in South Chailey
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. The work covers filter sections, heating and cooling coils and drain trays, and common reasons people get in touch are debris and leaves in the fresh air intake and rooms that smell stuffy when the system runs.
For a building in or near South Chailey, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Why deal with it now?
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. A fault that closes a site in a village like South Chailey affects everyone who depends on it.
What you pay reflects the actual work. That’s why every job is surveyed first, and why the quote is fixed before we start.
What you get with us
- A fixed price before any work starts
- Photo reports with every job

What your team can do, and what needs us
Day-to-day cleaning is something your team can do: 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.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.

What else we do in South Chailey
Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Keep filter changes on time and recorded
- File each AHU report in the maintenance log
- Report water on the plant room floor
- Book the next check in line with the report
Stick to the filter change schedule, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
Honest limits
Not every problem is solved by AHU cleaning, and we’ll tell you before work begins. It does not solve:
- Ductwork downstream of the unit, which is a separate clean
- Coils that are corroded or leaking and need replacing
- Building management system faults
If in doubt, call us on 0345 646 2711, or email photos and we will say what we think.
Parts of the system we cover
- Dampers and louvres

How it works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes half a day to a full day per unit, with large plant planned over several shifts, and we clear up before we go. We agree a date with you, plan the drive to South Chailey and turn up when the site is quiet.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Let us know when the site is closed or quiet
- Let us know how we reach the system, including roofs, risers and plant rooms
- Allow time for equipment near the work to be turned off and cool down
