AHU cleaning in Gossops Green
Our AHU cleans for sites in Gossops Green cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after photos in a report. We are often asked to deal with stale or musty smells from the ventilation and debris and leaves in the fresh air intake, across drain trays, heating and cooling coils and dampers and louvres.
Visits to a place like Gossops Green are fitted around opening hours. The method does not change: inspect first, clean, then record what was done.
The sign-off is always in writing: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

FAQs for Gossops Green
Can the work in Gossops Green be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Let us know the hours you are closed and we will book within them.
Can you clean school ventilation in Gossops Green during the holidays?
Yes. The holidays are the usual time for school work. Around Gossops Green, the Food Standards Agency lists about 20 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
Do you have insurance?
Yes. We carry full insurance and have been trading since 2009.
What do you do to protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Can we book visits on a schedule?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
What’s included in an AHU clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.
When should our AHU next be cleaned?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
Where does the waste go?
It leaves the site with us at the end of the visit. During the work, it’s contained so the area stays clean.
How the job changes from site to site
Internal casing and panels
Dust settles on every internal surface of the unit. Each section is cleaned from the intake through to the outlet.
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
What staff can safely do
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.

When to call us in Gossops Green
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
Look out for these warning signs:
- Plant that has been serviced but not cleaned
- Odours coming through the supply air
- Intake sections clogged with outdoor debris
- Drain trays holding standing water
Hospitals such as Crawley Hospital (about within half a mile north-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Gossops Green are no different.
What to look for in a quote
- How they set the interval to the next visit
- Whether a written report and photos are included
- Whether the whole system is included, or only the parts that are easy to reach
- If they look at the system before pricing
When it’s something else
We will always give you a straight diagnosis, so here’s what this work cannot put right:
- The supply and extract ducts, quoted separately
- Coils that are corroded or leaking and need replacing
- Airflow problems caused by the system’s design
Not sure which it is? You can call 0345 646 2711, or send details by email and we will tell you honestly before you book.
Parts of the system we cover
- Supply and extract fans
- Drain trays
- Heating and cooling coils
- Internal panels
- Dampers and louvres
- Filter sections
Looking after it afterwards
A little care between visits keeps the system in better shape. We recommend:
- Check the drain tray is emptying during routine visits
- Make sure the unit’s access doors open easily
- File each AHU report in the maintenance log
- Stick to the filter change plan
Once the clean is done, we send a TR19® certificate and a report with before and after photos. They belong in the plant or maintenance log.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
