About our AHU cleaning in Ardingly
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. If you are dealing with drain trays holding standing water and dust-coated heating and cooling coils, we can put it right, from supply and extract fans, internal panels and dampers and louvres onwards.
In a village or hamlet like Ardingly, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, 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.

Common problems we fix in Ardingly
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
If you notice any of these, it’s worth a diagnosis:
- Dirty fans and fan housings
- Filters that are clogged or overdue
- Leaves and litter drawn into the unit
- Stale or musty smells from the ventilation
If you run a surgery, dental practice or care home near Ardingly, clean ventilation matters as much to you as to a hospital like Princess Royal Hospital (about 3.9 miles south).

Why it’s worth doing now in Ardingly
If people in a building in Ardingly complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. A fault that closes a site in a village like Ardingly affects everyone who depends on it.
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before we start.
What you get with us
- A written report with photos after every visit
- Full insurance on every job
- Work around your opening hours, with 24/7 emergency cover
- Accredited under CHAS and SafeContractor, with ISO 9001

How we price AHU cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether we need access equipment or extra panels
- A single visit or a regular plan
- Where the site is and how we reach it
- The times the site is available
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.
What to send for a quote
There’s no need for technical detail. It helps if you can send:
- How we’d reach plant on a roof or in a plant room
- Close-ups of filters, grilles, hatches or access panels
- Any previous report or certificate
- Wide photos of the system and the area around it
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before any work starts.
Different parts, different methods
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with photos.
Your questions about AHU cleaning in Ardingly
Do you offer AHU cleaning in Ardingly?
Yes. We work across London and the South East, and Ardingly is part of that. To start, give us a ring on 0345 646 2711 or drop us a line with a few pictures of the system.
Do you work overnight in Ardingly?
Yes. We work evenings, overnight and at weekends. That way a site in Ardingly doesn’t have to lose a day’s trading. When you call us on 0345 646 2711, or send details by email, mention when the site is quiet.
What should I send you?
Some photos and a quick description of the system plus the address and your hours. If we need more, we will ask.
How far ahead should we book?
For planned work, earlier is better, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Do you give a certificate after the clean?
Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.
What does TR19 mean?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
Is a quote from pictures possible?
Often, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Can you clean the ducts connected to the AHU?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can survey both on the same visit.

Aftercare tips
Results last longer with the right care. Here’s what we suggest:
- Keep the area around the fresh air intake clear
- Report musty smells from the vents right away
- Look at the condensate drain whenever the unit is serviced
- Note any water around the unit or leaks below it
Restart the unit with your site team or maintenance contractor once we’ve finished. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
What we do, step by step
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Pictures of the system and its access let us plan the work in Ardingly before we set off.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
