About our AHU cleaning in Mulberry Green
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. We look at the unit first, from pictures or a site visit, and send you a fixed quote, so you know where you stand. If you’re dealing with debris and leaves in the fresh air intake and odours coming through the supply air, we can put it right.
Somewhere as small as Mulberry Green, ducted ventilation is normally 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.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

How the visit works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. Somewhere as small as Mulberry Green, the date and timings are agreed with you well before the day.
- 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.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.

What a clean won’t put right
We will always give you a straight diagnosis, so here’s what AHU cleaning will not do:
- Airflow problems caused by the system’s design
- Breakdowns that need a mechanical engineer
- Dirty ducts beyond the unit itself
If in doubt, call 0345 646 2711, or email photos and we will say what we think.
Where we work
- Drain trays
- Dampers and louvres

What AHU cleaning looks like in Mulberry Green
Food Standards Agency records list about 3 hospitals, care homes and childcare premises registered as food businesses within roughly a mile and a half of the centre of Mulberry Green. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. For Mulberry Green, the closest hospital is Essex County Hospital, roughly 4.5 miles east. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. Mulberry Green, about 46 miles from central London, is within our usual area. The visit is fixed around your opening hours, not ours.
School buildings such as The Stanway School are normally done in the holidays, so classrooms aren’t disturbed.
Mulberry Green is about 5 miles west of Colchester, in Essex. Mulberry Green gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where needed and a written report with photos. 644 places in Essex are on our list, large and small. Our Chelmsford page covers sites nearby (16 miles or so).

Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Change filters on schedule and log each change
- Watch for drips or damp patches near the plant
- Report musty smells from the vents straight away
- Make sure the unit’s access doors open easily
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
What happens if it’s left?
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. If the system at a site near Mulberry Green fails, there may be nowhere nearby to move to.

For landlords and multi-site operators
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
Common problems we fix in Mulberry Green
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
The symptoms we’re asked about most are:
- Drain trays holding standing water
- Air handling units with blocked filters
- Dirty coils holding back the airflow
- Plant that has been serviced but not cleaned
Hospitals such as Essex County Hospital (about 4.5 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Mulberry Green are no different.

Is a quote from pictures possible?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
What the work involves, part by part
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with photos.
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
