AHU cleaning in Cranbourne
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. Common call-outs are for condensate trays that won’t empty and units that have only ever had filter changes, on filter sections, internal panels and dampers and louvres.
Somewhere as small as Cranbourne, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
Facilities teams in offices, schools and healthcare sites book us too across Windsor and Maidenhead. Work can be phased by floor, building or site to keep disruption down.
Leave it or put it right?
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. Systems in rural buildings are often out of sight and out of mind.
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, call 0345 646 2711 or send us an email and we’ll give you an honest view and a fixed quote.
Why book with us
- A written report with photos after each visit
- In business since 2009
- Fixed quotes, normally within one working day
- CHAS and SafeContractor accredited, with ISO 9001

Looking after it afterwards
Aftercare is simple, and it helps at the next visit:
- Plan the next inspection before the last report gets filed away
- Store the TR19 paperwork where auditors can find it
- Look at the condensate drain whenever the unit is serviced
- Report stiff or damaged access doors
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
What your team can do, and what needs us
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Ventilation in Cranbourne buildings
About 2.8 miles south of Cranbourne is Heatherwood Hospital, the nearest hospital. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. Cranbourne, about 25 miles from central London, is within our usual area. The visit is fixed around your opening hours, not ours.
Wherever a school like Cranbourne Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Cranbourne: your questions answered
Can you work in Cranbourne outside opening hours?
Yes, nights and weekends are routine for us. The work in Cranbourne can fit around your hours. Let us know the hours you are closed and we’ll book within them.
Is AHU cleaning available in Cranbourne?
Yes, Cranbourne is covered. You can phone us on 0345 646 2711 or drop us a line and let us know what needs doing.
What’s TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
Do you clean the ductwork as well?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
How much notice should we give?
The more notice, the better, particularly for night and weekend visits. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.
Will the ventilation be off while you clean?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.
Are you fully insured?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.

How it works
A visit follows the same order every time: protect the area, isolate whatever needs isolating, carry out the AHU cleaning, tidy up and leave you the report. The visit itself takes from a few hours for a compact unit to a day or more for a large one. Seeing the system in pictures first means the trip to Cranbourne can be planned properly.
- We survey the unit from photos or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Find the previous report, if there is one
- Mention any parking or loading restrictions
- Plan for cooking equipment or plant to be off before we arrive
Get a fixed quote
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
Related advice
What we are called out for in Cranbourne
Filters that aren’t changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
Clients usually contact us when they notice something like this:
- Rooms that smell stuffy when the system runs
- Debris and leaves in the fresh air intake
- Dirty fans and fan housings
- Dirty coils holding back the airflow
Hospitals such as Heatherwood Hospital (about 2.8 miles south) show how much a building can rely on clean ventilation, and smaller healthcare sites near Cranbourne are no different.
