What your team can do, and what needs us
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
AHU cleaning in Roundbush, done properly
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with pictures, so the report shows exactly what was done. The work covers filter sections, internal panels and dampers and louvres, and people most often call us about blocked condensate drains and slimy trays and plant that needs cleaning after a refit.
In a village or hamlet like Roundbush, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

The process
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes half a day to a full day per unit, with large plant planned over several shifts. If the van will struggle with a lane or gateway near Roundbush, 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.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.

What AHU cleaning can’t fix
It’s worth knowing the limits before booking:
- A system that is undersized for the building
- Controls and BMS settings that run the unit
- Breakdowns that need a mechanical engineer
If in doubt, call 0345 646 2711, or email photos and we will say what we think.
What the work covers
- Dampers and louvres
- Supply and extract fans
- Filter sections
- Drain trays
- Heating and cooling coils
- Internal panels
Common problems we fix in Roundbush
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 some travels further into the unit.
If you notice any of these, it’s worth a diagnosis:
- Odours coming through the supply air
- Units that have only ever had filter changes
- Fan sections that haven’t been cleaned in years
- Dirty coils holding back the airflow
Classrooms and halls at schools such as Cold Norton Primary School are easiest to work in when pupils are away.
What your quote should include

Common questions in Roundbush
Do you work overnight in Roundbush?
Yes, evening, overnight and weekend work is normal for us. That way a site in Roundbush does not have to lose a day’s trading. Let us know the hours you’re closed and we will book within them.
Can you do AHU cleaning in Roundbush?
Yes, Roundbush is covered. Get in touch with the details and we’ll arrange a survey.
Do you need to switch the unit off?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we’ll advise on what to do next.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
Do you survey before quoting?
Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. A fixed quote follows.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Is there a report after cleaning?
Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.
Different parts, different methods
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins are not damaged.
