Different parts, different methods
Internal casing and panels
We open each section through its doors and close them securely when we’re done, and check every one is shut.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.
AHU cleaning in Steventon, done properly
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. We’re often asked to deal with air handling units never cleaned inside and rooms that smell stuffy when the system runs, across internal panels, dampers and louvres and heating and cooling coils.
Somewhere as small as Steventon, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
The report is your 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.

When it’s something else
AHU cleaning can’t fix everything, and we’d rather say so up front. It doesn’t solve:
- Ventilation that was badly designed in the first place
- The supply and extract ducts, quoted separately
- Faulty motors, drives or bearings
If in doubt, give us a ring on 0345 646 2711 or use the quote form and we will say what we think.

Steventon questions
Is Steventon within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Steventon included. The journey is planned ahead, so a few details about the route help.
Can the work in Steventon be done at night or at weekends?
Yes, nights and weekends are routine for us. It means the site in Steventon keeps running as normal. When you phone us on 0345 646 2711 or use the quote form, mention when the site is quiet.
Can we book visits on a schedule?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
How long does an AHU clean take?
Expect it to take a single shift for a typical unit, longer for large or heavily soiled ones. Size, layout and how dirty it is decide the rest, and we will confirm the time when we quote.
Do you repair air handling units?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
Do you work with multi-site operators?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
What do you clean inside the unit?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
How do you protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Multi-site and managed buildings
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.

- Fan sections that haven’t been cleaned in years
- Plant that has been serviced but not cleaned
- Odours coming through the supply air
