AHU cleaning in Breachwood Green
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after pictures in a report. The work covers supply and extract fans, dampers and louvres and internal panels, and common reasons people get in touch are units needing a clean before a new tenant or handover and leaves and litter drawn into the unit.
Work in a small place like Breachwood Green starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What we do, step by step
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes a single shift for a typical unit, longer for large or heavily soiled ones. The timing of a visit to Breachwood Green is set by you, and the travel is our side of the planning.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.

What a clean won’t put right
To be straight with you, some problems need a different fix:
- The supply and extract ducts, quoted separately
- Coils that are corroded or leaking and need replacing
- Faulty motors, drives or bearings

What the work covers
- Heating and cooling coils
- Dampers and louvres
- Supply and extract fans
- Internal panels
- Filter sections
- Drain trays
Signs you need AHU cleaning in Breachwood Green
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and that is where slime and odours start.
It’s time to book a visit if you see:
- Rooms that smell stuffy when the system runs
- Dirty fans and fan housings
- Blocked condensate drains and slimy trays
- Intake sections clogged with outdoor debris
Classrooms and halls at schools such as Breachwood Green Junior Mixed and Infant School are easiest to work in when pupils are away.
Questions to ask before you book
- How they set the interval to the next visit
- Which accreditations they hold, and whether you can check them
- How VAT is shown on the quote
- Whether the work can be done while the site is closed
What staff can safely do
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Between visits
No system stays clean for ever, but care slows the build-up. Our tips:
- Keep inspection doors on the unit in good order
- Plan the next inspection before the last report gets filed away
- File each AHU report in the maintenance log
- Check the drain tray is emptying during routine visits
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
What affects the cost of AHU cleaning
Every site gets its own quote. These are the things that affect it:
- How big the system is
- The times the site is available
- Whether it’s a one-off visit or part of a schedule
- Access, including roofs, risers and ceiling voids
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. You get a fixed price before work begins, so there are no surprises.

Photos let us diagnose from a distance. Try to include:
- The site address and the type of premises
