How we handle AHU cleaning in Chilson
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. If you’re dealing with condensate trays that won’t empty and coils clogged with dust and debris, we can help.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Fixed quotes for AHU cleaning in Chilson
Before we fix a price, we need to know a few things. We check:
- Any permits to work or inductions
- The number of sites or systems
- Where the site is and how we reach it
- The scale of the work
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.
Helping us quote
You don’t need the technical terms. It helps if you can send:
- Problems your staff have spotted
- Photos showing the whole system and its surroundings
- Your last certificate, test record or report
- Close-ups of filters, grilles, hatches or access panels
Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Questions from Chilson
Can the work in Chilson be done at night or at weekends?
Yes, nights and weekends are routine for us. It means the site in Chilson keeps running as normal. Let us know the hours you’re closed and we’ll book within them.
Will you come out to Chilson?
Yes, we work in villages as well as towns, and Chilson is covered. Photos of the system and directions to the site help us plan the visit.
How much notice do you need?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
What about areas you can’t get to?
Anything we can’t reach goes on the report, with pictures where possible, and we tell you what would make it reachable, for example new access panels.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we’ll talk you through the next steps.
How long will the unit be out of action?
Cleaning takes anything from half a day for one small unit to several shifts for a plant room full of them. Bigger units can be phased, so call us on 0345 646 2711 or send us an email to talk it through.
What does AHU cleaning cost?

Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.

Why it’s worth doing now in Chilson
Stuffy rooms and stale smells in a building in Chilson can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. Somewhere as small as Chilson, losing a kitchen or building to a fault is felt by everyone who uses it.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.

Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- Check the drain tray is emptying during routine visits
- Report stiff or damaged access doors
- Plan the next inspection before the last report gets filed away
- Keep filter changes on time and recorded
The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
What the work involves, part by part
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with photos so you can decide on any repairs.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
What we do, step by step
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, 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 Chilson before we set off.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Let us know about parking and loading
- Move anything stored near the system
- Let us know about permits to work or site inductions

What staff can safely do
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
