AHU cleaning in Little Waltham
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. If you are dealing with intake sections clogged with outdoor debris and odours coming through the supply air, we can help.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

How the visit works
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. From there, it takes from a few hours for a compact unit to a day or more for a large one. We agree a date with you, plan the drive to Little Waltham and turn up when the site is quiet.
- 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.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Let us know about permits to work or site inductions
- Arrange a key holder or contact on site
- Clear loose items from the work area

Why it’s worth doing now in Little Waltham
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. A fault that closes a site in a village like Little Waltham affects everyone who depends on it.
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before work begins.

What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.

What else we do in Little Waltham
What the work involves, part by part
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Keep the certificate and photo report with the plant records
- Change filters on schedule and log each change
- Do not ignore odours coming through the grilles
- Note any water around the unit or leaks below it
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
Common problems we fix in Little Waltham
Filters that are not changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
Common reasons sites call us are:
- Dirty coils holding back the airflow
- Dirty fans and fan housings
- Units that have only ever had filter changes
- Dirty filters cutting the airflow
Hospitals such as Broomfield Hospital (about 1 mile south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Little Waltham are no different.

Where does the waste go?
We take it away at the end of the visit. During the work, it’s contained to keep the area clean.
What if parts of the system can’t be reached?
Anything we cannot reach goes on the report, with photos where possible, and we explain what access is needed, such as extra access panels in ductwork.

Yes, we’re fully insured. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
