- Air handling units due a clean after building work
- Dust built up on fan impellers
- Condensate trays that won’t empty
What we do, step by step
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. For a village or hamlet like Bunce Common, tell us about narrow lanes, gates and parking when you book.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us about site rules, permits or sign-in
- Make sure equipment near the work can be switched off and left to cool

About our AHU cleaning in Bunce Common
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. If you’re dealing with drain trays holding standing water and coils clogged with dust and debris, we can help, from dampers and louvres, heating and cooling coils and drain trays onwards.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
The report is your system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Signs you need AHU cleaning in Bunce Common
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
Any of these means the system needs a check-up:
- Condensate trays that will not empty
- Filters that are clogged or overdue
- Dust built up on fan impellers
- Intake sections clogged with outdoor debris
Around Bunce Common, as anywhere, ventilation cleaning begins with an inspection.

- Whether the figure could change on the day
- Whether the work can be done while the site is closed
How we price AHU cleaning
The quote reflects the site in front of us. We consider:
- The size of the system
- The condition of the system
- One-off work versus a regular cycle
- Site requirements such as sign-in and permits
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before we start.
What we need to know
The more you tell us, the more accurate the quote. With your enquiry, please include:
- When the site is open and when it’s quiet
- Where the site is and what kind of site it is
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Wide pictures of the system and the area around it
There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, call us on 0345 646 2711, or email photos.

Does the AHU have to be shut down for cleaning?

Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
How the job changes from site to site
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
Looking after it afterwards
To keep the system working properly between visits:
- Note any water around the unit or leaks below it
- Flag stale or damp smells in the supply air
- Change filters on schedule and log each change
- Keep the area around the fresh air intake clear
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 inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
What a clean will not put right
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning will not do:
- Leaking heating or cooling coils
- Breakdowns that need a mechanical engineer
- A system that is undersized for the building
If you’re not sure, just call 0345 646 2711 or email us and we will give you a straight answer before booking.
