AHU cleaning in Maplehurst, done properly
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. Typical jobs include fan sections that haven’t been cleaned in years and air handling units never cleaned inside, on filter sections, dampers and louvres and heating and cooling coils.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

How the job changes from site to site
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.

For landlords and multi-site operators
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.
Aftercare tips
So the system stays in good health:
- Check the drain tray is emptying during routine visits
- Book the next check in line with the report
- Flag stale or damp smells in the supply air
- Clear leaves and litter away from the intake
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
AHU cleaning in Maplehurst: local notes
About 35 miles out from central London, Maplehurst is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site. Horsham Hospital is the nearest hospital, about 4.3 miles north of Maplehurst. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Healthcare ventilation, from large hospitals like Horsham Hospital (about 4.3 miles north) to small clinics, depends on clean filters, coils and ducts. School buildings such as St Andrew's CofE Primary School are typically done in the holidays, so classrooms are not disturbed.

What happens if it’s left?
Stuffy rooms and stale smells in a building in Maplehurst can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. With notice, the visit to Maplehurst can be fitted around your bookings and events.

- Internal panels
- Dampers and louvres

What staff can safely do
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
