How we handle AHU cleaning in Rustington
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. 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. The work covers heating and cooling coils, dampers and louvres and drain trays, and people most often call us about air handling units due a clean after building work and dust built up on fan impellers.
In a place like Rustington, air handling units are often tucked into roof spaces or small plant rooms, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.
It’s worth checking any contractor’s accreditations. 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.

What a clean will not put right
We will not sell you work that does not address the problem, so these are the things it will not cover:
- Dirty ducts beyond the unit itself
- Coils that are corroded or leaking and need replacing
- Faulty motors, drives or bearings
If you’re not sure, just phone us on 0345 646 2711, or send details by email and we will give you a straight answer before booking.
What the work covers
- Heating and cooling coils
- Dampers and louvres
- Supply and extract fans
- Drain trays
- Internal panels
- Filter sections
Different parts, different methods
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
The process
A visit follows the same order every time: protect the area, make the system safe, do the work, tidy up and leave you the report. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. Evenings, weekends or a closed day all work for a site in a place like Rustington.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Before we arrive
- Mention any sign-in, permit or induction we need
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Move anything stored near the system
Getting a quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before work begins.
Related advice
What your team can do, and what needs us
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
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, and that is where we come in.
Rustington: your questions answered
Can a school’s ventilation in Rustington be done out of term time?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 26 schools and colleges with food registrations within roughly a mile and a half of Rustington. Just phone us on 0345 646 2711 or use the quote form with your term dates and we’ll plan around them.
Can the work in Rustington be done at night or at weekends?
Yes, nights and weekends are routine for us. The site is handed back ready to open. When you ring 0345 646 2711 or send us an email, mention when the site is quiet.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Do you clean the ductwork as well?
Yes, the ductwork, grilles and diffusers the unit serves. We’ll tell you after the survey whether the ducts need it.
Do you work in Rustington?
Yes. Our technicians work in Rustington, as part of our area across London and the South East.
Do you offer maintenance contracts?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
Do you give a certificate after the clean?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
What happens to the waste?
It leaves the site with us when we go. While we work, it’s kept contained to keep the area clean.
What happens if it’s left?
Stuffy rooms and stale smells in a building in Rustington can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. Even a site near Rustington that’s only busy part of the week needs its system checked on a schedule.
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we will price it together.

Between visits
Aftercare is simple, and it makes the next visit easier:
- Diary the inspection date recommended in the report
- Clear leaves and litter away from the intake
- Change filters on schedule and log each change
- Flag stale or damp smells in the supply air
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
