- Dirty ducts beyond the unit itself
- Coils that are corroded or leaking and need replacing
- A system that is undersized for the building

How we handle AHU cleaning in Ellen's Green
If the units serving a building in Ellen's Green have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. The work covers internal panels, supply and extract fans and dampers and louvres, and common reasons people get in touch are drain trays holding standing water and air handling units due a clean after building work.
For a building in or near Ellen's Green, access is agreed in advance and the visit is planned around the journey.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What affects the cost of AHU cleaning
The price is fixed before any work begins. It’s based on:
- When the work can happen, such as evenings, overnight or weekends
- How easy every part is to reach
- Travel, parking and unloading
- Any permits to work or inductions
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, call 0345 646 2711, or email photos for straight advice and a fixed quote.
What to send for a quote
To speed up the quote, send us:
- Photos showing the whole system and its surroundings
- The paperwork from the last visit, if you have it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Where the site is and what kind of site it is
Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
What happens on the day
A visit follows the same order every time: protect the area, make the system safe, do the work, tidy up and hand over the paperwork. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. If you can send photos, we can arrive in Ellen's Green knowing what to expect.
- First we agree when the unit can be switched off, including evenings or weekends.
- 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.
Preparing for the visit
- Clear loose items from the work area
- Let us know about parking and loading
- Mention any sign-in, permit or induction we need

Related advice
In-house cleaning or a specialist?
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
What the work involves, part by part
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated with your site team.

Between visits
Think of this as the after-treatment advice, short and simple:
- Keep inspection doors on the unit in good order
- File each AHU report in the maintenance log
- Don’t store bins or materials near the intake
- Flag stale or damp smells in the supply air
We recommend when the unit should next be inspected or cleaned, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.

Anything we cannot reach goes on the report, with pictures where possible, and we tell you what would make it reachable, such as extra access panels in ductwork.
Do you work evenings or weekends?
Yes. We time the work to fit the building’s hours. Healthcare and care settings are planned with staff.
How much notice should we give?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.

What happens if it’s left?
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that does not feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. In a place like Ellen's Green, ductwork and fans are easy to forget until something goes wrong.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we will price it together.
