When to call us in Belvedere
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and that is where slime and odours start.
Most sites get in touch when they notice one of these:
- Dust built up on fan impellers
- Plant that needs cleaning after a refit
- Intake sections clogged with outdoor debris
- Dirty coils holding back the airflow
If you manage shops or offices close to Belvedere station, a TR19® Air inspection shows whether the ductwork needs cleaning.

How we handle AHU cleaning in Belvedere
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. Typical jobs include plant that has been serviced but not cleaned and blocked condensate drains and slimy trays, across dampers and louvres, drain trays and filter sections.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. In a building in Belvedere, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Honest limits
Some problems need a different service or another trade:
- Ventilation that was badly designed in the first place
- Mechanical faults with motors, belts or bearings
- Ductwork downstream of the unit, which is a separate clean

What we work on in Belvedere
- Internal panels
- Dampers and louvres
- Filter sections
- Supply and extract fans
- Drain trays
- Heating and cooling coils
Between visits
Here’s the after-treatment advice, short and simple:
- Stick to the filter change plan
- Keep the certificate and photo report with the plant records
- Report stiff or damaged access doors
- Report musty smells from the vents straight away
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
