FAQs for Tilgate
Can you work in Tilgate outside opening hours?
Yes. We work evenings, overnight and at weekends. It means the site in Tilgate keeps running as normal. Let us know the hours you’re closed and we’ll book within them.
Do you cover smaller places like Tilgate?
Yes. Villages and rural sites across the South East are part of our work, Tilgate included. Photos of the system and directions to the site help us plan the visit.
Can you price the work without visiting?
Usually, yes. Send a few wide pictures plus close-ups of panels, filters or grilles, and we usually come back within one working day. Some sites still need a visit, and we will say so.
How long does it take to clean an air handling unit?
The work takes one overnight shift for many single units, with bigger plant phased. Bigger units can be phased, and you can call us on 0345 646 2711, or email photos to plan it.
Does the AHU have to be shut down for cleaning?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
Can you come out in an emergency?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. We don’t leave it behind.
Are you insured?
Yes. Full insurance covers our work, and we’ve been trading since 2009.
About our AHU cleaning in Tilgate
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. The work covers heating and cooling coils, dampers and louvres and supply and extract fans, and the jobs we see most are debris and leaves in the fresh air intake and dirty filters cutting the airflow.
For a building near Tilgate, the visit is planned around how it’s used, and the journey is planned ahead. The work is the same as in any town: inspect, clean, record.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

In-house cleaning or a specialist?
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Signs you need AHU cleaning in Tilgate
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
Most sites get in touch when they notice one of these:
- Odours coming through the supply air
- Units needing a clean before a new tenant or handover
- Units that have only ever had filter changes
- Condensate trays that won’t empty
If you manage offices or shops near Crawley station, their ventilation can be inspected and cleaned out of hours.

Part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.

What else we do in Tilgate
Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare across West Sussex. Larger estates can be phased building by building around the people who use them.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
Leave it or put it right?
Standing water in a drain tray doesn’t clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. A quieter site near Tilgate still needs its system looked after.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before we start.

Between visits
Results last longer with the right care. Here’s what we suggest:
- Watch for drips or damp patches near the plant
- Clear leaves and litter away from the intake
- Report stiff or damaged access doors
- Don’t ignore odours coming through the grilles
The report suggests a date for the next inspection or clean, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
What we do, step by step
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before we start, and floors and nearby surfaces are sheeted. The work itself takes one overnight shift for many single units, with bigger plant phased. In a place like Tilgate, we fit the visit around your hours.
- 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.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Getting ready for the visit
- Have your last certificate or report to hand
- Let us know how we reach the system, including roofs, risers and plant rooms
- Agree a time when the area can be out of use
