Why it’s worth doing now in Marsh Green
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. A fault that closes a site in a village like Marsh Green affects everyone who depends on it.
Putting the work off seldom saves money. 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 and we will give you an honest view and a fixed quote.

AHU cleaning in Marsh Green, done properly
Our AHU cleans for sites in Marsh Green cover the parts that collect dirt: 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. Typical jobs include rooms that smell stuffy when the system runs and blocked condensate drains and slimy trays, on drain trays, internal panels and supply and extract fans.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What’s included in an AHU clean?
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.
What information do you need?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.

Do you clean the ductwork as well?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
What the work involves, part by part
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey so the quote reflects it.
How it works
Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. We agree a date with you, plan the drive to Marsh Green and turn up when the site is quiet.
- 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.
How to prepare
- Dig out any earlier paperwork for the system
- Move anything stored near the system
- Tell us where we can park and unload

What staff can safely do
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
What we’re called out for in Marsh Green
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
What we are most often called out for:
- Units needing a clean before a new tenant or handover
- Filters that are clogged or overdue
- Dust built up on fan impellers
- Debris and leaves in the fresh air intake
Ventilation work in and around Marsh Green is risk-based: inspect, then clean what needs it.
What your quote should include
- Whether they recommend a next date
- Whether the quote is based on a survey or photos
- Which accreditations they hold, and whether you can check them
- Whether inaccessible sections are listed on the report
Looking after it afterwards
After the visit, a few habits help the work last:
- Keep filter changes on time and recorded
- File each AHU report in the maintenance log
- Make sure condensate is draining away
- Make sure the unit’s access doors open easily
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
When something else is needed
It’s worth knowing the limits before booking:
- Leaking heating or cooling coils
- A system that’s undersized for the building
- Problems with the unit’s controls or sensors
If in doubt, call us on 0345 646 2711, or email photos and we will say what we think.
