About our AHU cleaning in Chilton
Our AHU cleans for sites in Chilton cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. Common call-outs are for air handling units due a clean after building work and condensate trays that won’t empty, on internal panels, filter sections and drain trays.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Nothing is signed off by word of mouth: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

How the visit works
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. Most of the time goes on the work itself, and that takes half a day to a full day per unit, with large plant planned over several shifts. If you can send pictures, we can arrive in Chilton knowing what to expect.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Mention any locked doors, roof access or ceiling voids
- Move anything stored near the system
- Let us know about parking and loading

Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
Advice
Aftercare tips
Here’s the after-treatment advice, short and simple:
- Clear leaves and litter away from the intake
- Keep filter changes on time and recorded
- File each AHU report in the maintenance log
- Note any water around the unit or leaks below it
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
Common questions in Chilton
Can the work in Chilton 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. Just ring 0345 646 2711, or email photos with your opening times and we will plan around them.
Do you work in villages like Chilton?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
What types of premises do you cover?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
What if parts of the system can’t be reached?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Can you come out in an emergency?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we’ll advise on what to do next.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Each site gets its own report and photos.
Do you repair air handling units?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.
How much does AHU cleaning cost in Chilton?
We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before we start.
When it’s something else
We will always give you a straight diagnosis, so here’s what this work can’t put right:
- Controls and BMS settings that run the unit
- Breakdowns that need a mechanical engineer
- Damaged coils beyond cleaning
If you are not sure, just call 0345 646 2711 or email us and we will give you a straight answer before you book.
Where we work
- Dampers and louvres
- Heating and cooling coils
- Internal panels
- Filter sections
- Supply and extract fans
- Drain trays
What the work involves, part by part
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
Leave it or put it right?
Stuffy rooms and stale smells in a building in Chilton can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. If the system at a site near Chilton fails, there may be nowhere nearby to move to.

No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Look out for these warning signs:
- Dust built up on fan impellers
- Units needing a clean before a new tenant or handover
- Blocked condensate drains and slimy trays
- Filters that are clogged or overdue
