Part by part
Drain trays
Older trays can corrode and start leaking. We record their condition with photos so you can decide on any repairs.
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
AHU cleaning in Paynes Green
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from pictures or a site visit, and send you a fixed quote, so you know where you stand. If you’re dealing with air handling units due a clean after building work and debris and leaves in the fresh air intake, we can help.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

How the visit works
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes one overnight shift for many single units, with bigger plant phased. If you can send photos, we can arrive in Paynes Green 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.
Getting ready for the visit
- Tell us where we can park and unload
- Mention any locked doors, roof access or ceiling voids

Between visits
To keep the system working properly between visits:
- Keep filter changes on time and recorded
- Make sure condensate is draining away
- Watch for drips or damp patches near the plant
- Report musty smells from the vents straight away
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
