AHU cleaning for kitchens and businesses in Balls Cross
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. The work covers supply and extract fans, internal panels and filter sections, and common reasons people get in touch are blocked condensate drains and slimy trays and units that have only ever had filter changes.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

When it’s something else
A few issues sit outside what this work can do:
- Ductwork downstream of the unit, which is a separate clean
- Breakdowns that need a mechanical engineer
- Leaking heating or cooling coils

Balls Cross: your questions answered
Do you cover smaller places like Balls Cross?
Yes. Villages and rural sites across the South East are part of our work, Balls Cross included. Let us know about access, parking and anything unusual about getting there when you book.
Can you do AHU cleaning in Balls Cross?
Yes. We work across London and the South East, and Balls Cross is part of that. You can ring 0345 646 2711 or use the quote form and tell us what needs doing.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
Do you clean the ductwork as well?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What about areas you can’t get to?
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.
Can you look after several sites?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Each site gets its own report and pictures.
How the job changes from site to site
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey, before we quote.
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated with your site team.
Between visits
Simple habits between visits make a real difference. Our advice:
- Check the drain tray is emptying during routine visits
- Note any water around the unit or leaks below it
- Report stiff or damaged access doors
- Clear leaves and litter away from the intake
Once the clean is done, we send a TR19® certificate and a report with before and after photos. They belong in the plant or maintenance log.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.
What your team can do, and what needs us
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
What happens on the day
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. Somewhere as small as Balls Cross, 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.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Name a contact who can let us in at the agreed time
Get a fixed quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before work begins.

How we price AHU cleaning
Your quote is based on your site. We take into account:
- Working hours and out-of-hours timing
- Where the site is and how we reach it
- Site requirements such as sign-in and permits
- The condition we find in the survey
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
What to send for a quote
A few details help us quote accurately. With your enquiry, please include:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The times we could work without disrupting the site
- The site address and the type of premises
- A few general shots of the system
For a fixed quote, call us on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You will typically have a quote within one working day.
What we’re called out for in Balls Cross
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and the finer material travels on.
These are the problems we see most often:
- Rooms that smell stuffy when the system runs
- Leaves and litter drawn into the unit
- Coils clogged with dust and debris
- Plant that has been serviced but not cleaned
Whether the building is in Balls Cross itself or nearby, filters, coils, drain trays and ducts are all part of the work.
