Trottiscliffe AHU cleaning
AHU cleaning in Trottiscliffe from ventilation hygiene specialists trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Dust-coated heating and cooling coils
- Units needing a clean before a new tenant or handover
- Drain trays holding standing water
What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
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.
How we handle AHU cleaning in Trottiscliffe
Where a building in Trottiscliffe has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. We are often asked to deal with stale or musty smells from the ventilation and drain trays holding standing water, on dampers and louvres, supply and extract fans and internal panels.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Every visit ends with a written report and photos, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How it works
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. The middle part takes longest, and that takes one overnight shift for many single units, with bigger plant phased. Somewhere like Trottiscliffe, lanes, gates and parking are worth mentioning in advance.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about permits to work or site inductions
- Agree a time when the area can be out of use

Related advice
Keeping the system healthy
A little care between visits keeps the system in better shape. We recommend:
- Report stiff or damaged access doors
- Report musty smells from the vents right away
- Look at the condensate drain whenever the unit is serviced
- Keep filter changes on time and recorded
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.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
What affects the quote in Trottiscliffe
The diagnosis comes before the price. The main factors are:
- Working hours and out-of-hours timing
- Site rules, permits and inductions
- How many systems or sites are involved
- A single visit or a regular plan
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 are not sure what’s needed, give us a ring on 0345 646 2711 or drop us a line for straight advice and a fixed quote.
Asking for a quote
When you call or email, these details help:
- When the site is open and when it’s quiet
- The site address and the type of premises
- Your last certificate, test record or report
- How we’d reach plant on a roof or in a plant room
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before any work starts.

Common problems we fix in Trottiscliffe
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
Any of these means the system needs a check-up:
- Plant that needs cleaning after a refit
- Rooms that smell stuffy when the system runs
- Fan sections that haven’t been cleaned in years
- Coils clogged with dust and debris
School buildings such as Trottiscliffe Church of England Primary School are usually done in the holidays, so classrooms are not disturbed.

Trottiscliffe questions
Do you work in villages like Trottiscliffe?
Yes, we work in villages as well as towns, and Trottiscliffe is covered. A survey first, from photos or a visit, means we arrive with the right kit.
Do you work at weekends in Trottiscliffe?
Yes. We work evenings, overnight and at weekends. That way a site in Trottiscliffe doesn’t have to lose a day’s trading. Just give us a ring on 0345 646 2711 or email us with your opening times and we will plan around them.
Do you look at the system first?
Yes. Every job is surveyed first, from your photos and details, or with a visit where necessary. Then you get a fixed quote.
What if parts of the system cannot be reached?
Anything we can’t reach goes on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
How much does AHU cleaning cost?
It depends on the site, so we quote each one individually. For a quote, call 0345 646 2711 or email us and tell us about the site and its opening hours.
Will the ventilation be off while you clean?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. At the end, the area is cleaned down.
How long does an AHU clean take?
The work takes a single shift for a typical unit, longer for large or heavily soiled ones. Bigger units can be phased, and you can phone us on 0345 646 2711 or use the quote form to plan it.
What the work involves, part by part
Fans and fan sections
Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
