AHU cleaning in Wivelrod, done properly
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, once the unit has been shut down and isolated. We’re often asked to deal with fan sections that haven’t been cleaned in years and dust-coated heating and cooling coils, across drain trays, filter sections and internal panels.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
We have been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

How the visit works
Everything the job needs comes with us, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. The visit takes anything from half a day for one small unit to several shifts for a plant room full of them. Photos of the system and how to reach it help us plan a visit to Wivelrod.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Make sure someone can let us in and lock up afterwards
- Mention any sign-in, permit or induction we need
How to get a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before we start.

Different parts, different methods
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.

Why act early in Wivelrod
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. In a small place like Wivelrod, a system that fails can take a site out of use.

Landlords, agents and facilities managers
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
When to call us in Wivelrod
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Wivelrod, that is air they breathe for hours at a time.
Look out for these warning signs:
- Rooms that smell stuffy when the system runs
- Air handling units with blocked filters
- Coils clogged with dust and debris
- Fan sections that haven’t been cleaned in years
Around Wivelrod, as anywhere, ventilation cleaning begins with an inspection.
What your quote should include
- Whether the quote shows VAT
- Exactly which parts of the system are covered
- If the quote is a fixed price or an estimate
- What paperwork you get at the end
Keeping the system healthy
No system stays clean for ever, but care slows the build-up. A few tips:
- Keep inspection doors on the unit in good order
- Clear leaves and litter away from the intake
- Keep the certificate and photo report with the plant records
- Change filters on schedule and log each change
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
