AHU cleaning in Old Basing
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. The work covers internal panels, heating and cooling coils and supply and extract fans, and people most often call us about coils clogged with dust and debris and plant that has been serviced but not cleaned.
In a place like Old Basing, air handling units are often tucked into roof spaces or small plant rooms, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.
Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Signs you need AHU cleaning in Old Basing
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Any of these means the system needs a check-up:
- Debris and leaves in the fresh air intake
- Units that have only ever had filter changes
- Air handling units with blocked filters
- Dust built up on fan impellers
Wherever a school like Old Basing Infant School has ducted ventilation, a half-term visit keeps the work out of lesson time.

The process
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes a single shift for a typical unit, longer for large or heavily soiled ones, and we clear up before we go. Around Old Basing, access is normally simpler than in a town centre, though gates and roof access are worth mentioning.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Mention any sign-in, permit or induction we need
- Arrange a key holder or contact on site
- Agree a time when the area can be out of use

Part by part
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.

Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
