AHU cleaning for kitchens and businesses in Kilnwood Vale
We clean air handling units for buildings in Kilnwood Vale and across West Sussex, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. Typical jobs include drain trays holding standing water and dust built up on fan impellers, on internal panels, filter sections and heating and cooling coils.
Work in a small place like Kilnwood Vale starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
A written report with pictures follows each visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Keeping the system healthy
To keep the system working properly between visits:
- Plan the next inspection before the last report gets filed away
- Look at the condensate drain whenever the unit is serviced
- Watch for drips or damp patches near the plant
- Keep filter changes on time and recorded
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
Staff cleaning versus specialist work
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. Reaching it takes a specialist with the right equipment.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
How it works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes half a day to a full day per unit, with large plant planned over several shifts, and we clear up before we go. Pictures of the system and its access let us plan the work in Kilnwood Vale before we set off.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Mention any locked doors, roof access or ceiling voids
- Let us know when the site is closed or quiet
- Mention any parking or loading restrictions
Getting a quote
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To start, call us on 0345 646 2711, or email photos.

Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Kilnwood Vale’s nearest hospital, Crawley Hospital, is about 2.4 miles north-east.

Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
