About our AHU cleaning in Hedgerley Green
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. We are often asked to deal with dirty fans and fan housings and filters that are clogged or overdue, across drain trays, internal panels and heating and cooling coils.
In a village or hamlet like Hedgerley Green, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
The sign-off is always in writing: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What staff can safely do
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
The process
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes one overnight shift for many single units, with bigger plant phased. In a small place like Hedgerley Green, the journey is planned ahead and the visit arranged around the site’s hours.
- 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.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Let us know when the site is closed or quiet
- Make sure equipment near the work can be switched off and left to cool
- Clear the space around the work

Is AHU cleaning available in Hedgerley Green?

Are you fully insured?

Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
How do you keep the site clean during the work?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Which sectors do you work in?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
What the work involves, part by part
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
For landlords and multi-site operators
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.
Facilities teams in offices, schools and healthcare sites book us too across Slough. Work can be phased by floor, building or site around the people who use them.
Common problems we fix in Hedgerley Green
Whatever surrounds a building in Hedgerley Green, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and some travels further into the unit.
Common reasons sites call us include:
- Air handling units due a clean after building work
- Dust built up on fan impellers
- Air handling units never cleaned inside
- Stale or musty smells from the ventilation
For schools like Gayhurst School, the holidays are the usual time to inspect and clean ventilation.
Before booking anyone
- Whether the quote shows VAT
- Proof of accreditation you can verify
- Whether the work can be done while the site is closed
