How we handle AHU cleaning in Nether Worton
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. The work covers supply and extract fans, dampers and louvres and drain trays, and the jobs we see most are stale or musty smells from the ventilation and drain trays holding standing water.
In a village or hamlet like Nether Worton, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
The paperwork matters as much as the work. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Part by part
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that won’t bend or flatten the fins.
Signs you need AHU cleaning in Nether Worton
Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
Look out for these warning signs:
- Units that have only ever had filter changes
- Dirty fans and fan housings
- Drain trays holding standing water
- Intake sections clogged with outdoor debris
In Nether Worton, we look inside the system before deciding what needs cleaning.

How it works
A visit follows the same order every time: sheeting and protection first, make the system safe, carry out the AHU cleaning, tidy up and leave you the report. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Pictures of the system and its access let us plan the work in Nether Worton before we set off.
- 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.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Agree a time when the area can be out of use
- Dig out any earlier paperwork for the system

Advice
Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Make sure the unit’s access doors open easily
- Do not ignore odours coming through the grilles
- Keep filter changes on time and recorded
- Don’t store bins or materials near the intake
Keep filter changes on schedule between cleans, 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.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
Why it’s worth doing now in Nether Worton
A clean unit feeds cleaner air into the ductwork, so the whole system stays cleaner for longer. It also means the next inspection has less to find. Rural sites can’t always move to another kitchen or room when something fails.
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, give us a ring on 0345 646 2711 or use the quote form for straight advice and a fixed quote.
