The process

In a small place like Stanford Common, the journey is planned ahead and the visit arranged around the site’s hours.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.

How we handle AHU cleaning in Stanford Common
If the units serving a building in Stanford Common have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. Common call-outs are for air handling units with blocked filters and dirty fans and fan housings, across dampers and louvres, supply and extract fans and drain trays.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Keeping the system healthy
After the visit, a few habits help the work last:
- Report musty smells from the vents straight away
- Keep the certificate and photo report with the plant records
- Watch for drips or damp patches near the plant
- Diary the inspection date recommended in the report
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
When to call us in Stanford Common
Whatever surrounds a building in Stanford Common, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and some travels further into the unit.
These are the problems we see most often:
- Dirty filters cutting the airflow
- Dirty fans and fan housings
- Dirty coils holding back the airflow
- Air handling units never cleaned inside
If you run a surgery, dental practice or care home near Stanford Common, clean ventilation matters as much to you as to a hospital like Brookwood Hospital (about 2.6 miles north-east).

What AHU cleaning cannot fix
Before you book, it helps to know what’s not included:
- Mechanical faults with motors, belts or bearings
- Ventilation that was badly designed in the first place
- Ductwork downstream of the unit, which is a separate clean
If you are not sure, just phone us on 0345 646 2711 or email us and we’ll give you a straight answer.
Where we work
- Heating and cooling coils
- Dampers and louvres
- Drain trays

For landlords and multi-site operators
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
