How we handle AHU cleaning in Chignall Smealy
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. The work covers dampers and louvres, supply and extract fans and heating and cooling coils, and people most often call us about dirty fans and fan housings and stale or musty smells from the ventilation.
Work in a small place like Chignall Smealy starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Think of the report as the 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.

Aftercare tips
Think of this as the after-treatment advice, short and simple:
- Stick to the filter change plan
- Make sure the unit’s access doors open easily
- Watch for drips or damp patches near the plant
- Check the drain tray is emptying during routine visits
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Do not let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.

Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
