When it’s something else
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It will not put right:
- Faulty motors, drives or bearings
- The supply and extract ducts, quoted separately
- Airflow problems caused by the system’s design

AHU cleaning in Finchingfield
No two plant rooms are the same, 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 give you a fixed quote, so you know where you stand. Typical jobs include plant that has been serviced but not cleaned and coils clogged with dust and debris, across internal panels, heating and cooling coils and dampers and louvres.
For a building in or near Finchingfield, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How it works
A visit follows the same order every time: sheeting and protection first, make the system safe, carry out the AHU cleaning, tidy up and leave you the report. On site, the work takes from a few hours for a compact unit to a day or more for a large one. If the van will struggle with a lane or gateway near Finchingfield, let us know and we will plan around it.
- We look at the unit and the plant area during the survey.
- 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.
How to prepare
- Clear loose items from the work area
- Let us know about parking and loading
- Mention any sign-in, permit or induction we need

Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Flag stale or damp smells in the supply air
- Change filters on schedule and log each change
- Plan the next inspection before the last report gets filed away
- File each AHU report in the maintenance log
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.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
What staff can safely do
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Common problems we fix in Finchingfield
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and slime and smells soon follow.
Look out for these warning signs:
- Plant that has been serviced but not cleaned
- Filters that are clogged or overdue
- Drain trays holding standing water
- Dirty fans and fan housings
Every job around Finchingfield ends with a record of what was cleaned and what was found.

Common questions in Finchingfield
Do you work at weekends in Finchingfield?
Yes, evening, overnight and weekend work is normal for us. The work in Finchingfield can fit around your hours. Your opening times are the first thing we ask for.
Do you cover smaller places like Finchingfield?
Yes. Finchingfield is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Can you price the work without visiting?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
How far ahead should we book?
For planned work, earlier is better, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Is there a survey before the work?
Yes. Photos often do the job, and larger or hidden systems get a visit.
What happens to the waste?
It leaves the site with us when we go. During the work, it’s contained to keep the area clean.
What happens if you cannot reach some of it?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
