How we handle AHU cleaning in Radfall
If the units serving a building in Radfall have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. The work covers drain trays, heating and cooling coils and filter sections, and the jobs we see most are debris and leaves in the fresh air intake and fan sections that haven’t been cleaned in years.
In a village or hamlet like Radfall, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

For landlords and multi-site operators
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.

Questions from Radfall
Do you work in villages like Radfall?
Yes, we work in villages as well as towns, and Radfall is covered. A survey first, from pictures or a visit, means we arrive with the right kit.
Can the work in Radfall be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. It means the site in Radfall keeps running as normal. Your opening times are the first thing we ask for.
Can you come out in an emergency?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
Can you clean the ducts connected to the AHU?
Yes, the ductwork, grilles and diffusers the unit serves. The survey shows whether the ducts need cleaning now.
Can you look after several sites?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
Will you repair the fan or motor?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We will flag anything we notice during the clean.
Do you need to switch the unit off?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
What accreditations do you have?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
What the work involves, part by part
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe with your site team.
What happens if it’s left?
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. Systems in rural buildings are often out of sight and out of mind.
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.

Looking after it afterwards
After the visit, a few habits help the work last:
- Plan the next inspection before the last report gets filed away
- Don’t ignore odours coming through the grilles
- Clear leaves and litter away from the intake
- Look at the condensate drain whenever the unit is serviced
We recommend when the unit should next be inspected or cleaned, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
How it works
Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. We agree a date with you, plan the drive to Radfall and turn up when the site is quiet.
- We agree a shutdown window that suits the building.
- 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.
- We take after pictures and issue the certificate and report.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Make sure someone can let us in and lock up afterwards
- Let us know how we reach the system, including roofs, risers and plant rooms

What we are called out for in Radfall
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
Signs it’s time to call us include:
- Air handling units due a clean after building work
- Fan sections that haven’t been cleaned in years
- Rooms that smell stuffy when the system runs
- Intake sections clogged with outdoor debris
For schools like The Whitstable School, the holidays are the usual time to inspect and clean ventilation.
