AHU Cleaning in Cheeseman's Green
We cover Cheeseman's Green for cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces. Fixed quotes, work around your opening hours and photo reports on every job.
- Rooms that smell stuffy when the system runs
- Fan sections that haven’t been cleaned in years
- Dirty coils holding back the airflow
Between visits
Good habits slow the build-up between visits. Our tips:
- Look at the condensate drain whenever the unit is serviced
- Stick to the filter change plan
- Keep the area around the fresh air intake clear
- Keep inspection doors on the unit in good order
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can survey both.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
AHU cleaning in Cheeseman's Green
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. The work covers internal panels, supply and extract fans and filter sections, and common reasons people get in touch are dirty fans and fan housings and rooms that smell stuffy when the system runs.
For a building in or near Cheeseman's Green, access is agreed in advance and the visit is planned around the journey.
A written report with pictures follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Staff cleaning versus specialist work
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
The process
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. The middle part takes longest, which takes one overnight shift for many single units, with bigger plant phased. Photos of the system and how to reach it help us plan a visit to Cheeseman's Green.
- 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.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Find the previous report, if there is one
- Mention any sign-in, permit or induction we need
