AHU cleaning in West Chiltington Common, done properly
Our AHU cleans for sites in West Chiltington Common cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after photos in a report. Common call-outs are for condensate trays that won’t empty and intake sections clogged with outdoor debris, across filter sections, supply and extract fans and drain trays.
In a smaller place like West Chiltington Common, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Smaller systems still gather dust and need inspecting.
The report is your system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Common problems we fix in West Chiltington Common
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
Most sites get in touch after spotting one of these:
- Dirty coils holding back the airflow
- Air handling units with blocked filters
- Odours coming through the supply air
- Air handling units never cleaned inside
If you manage a school such as West Chiltington Community Primary School, ventilation cleaning is best booked for the holidays.

What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used, and we’ll suggest a schedule and quote for it.

Typically the clean takes from a few hours for a compact unit to a day or more for a large one. The shutdown is planned to fit, including evenings or weekends.
Different parts, different methods
Drain trays
The drain tray collects water from the cooling coil. Standing water and slime are removed and the outlet is checked.
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.

What staff can safely do
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
What happens on the day
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes from a few hours for a compact unit to a day or more for a large one. Because the survey comes first, a visit to West Chiltington Common can normally be finished without a second trip.
- We survey the unit from pictures or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Arrange a key holder or contact on site
- Find the previous report, if there is one
- Clear loose items from the work area
Ask for a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

When something else is needed
We will not sell you work that does not address the problem, so here are the limits:
- Damaged coils beyond cleaning
- Problems with the unit’s controls or sensors
- Faulty motors, drives or bearings
If in doubt, phone us on 0345 646 2711 or drop us a line and we will say what we think before you book.

What happens if it’s left?
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. Systems on quieter sites still build up dirt and wear, just more slowly.

Multi-site and managed buildings
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so each one has its own record.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
