AHU cleaning in Nettlestead Green
If the units serving a building in Nettlestead Green have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. Common call-outs are for dust built up on fan impellers and units needing a clean before a new tenant or handover, on supply and extract fans, heating and cooling coils and dampers and louvres.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What happens if it’s left?

What else we do in Nettlestead Green
Keeping the system healthy
Looking after the system between visits is straightforward, and it helps at the next visit:
- Store the TR19 paperwork where auditors can find it
- Clear leaves and litter away from the intake
- Change filters on schedule and log each change
- Make sure condensate is draining away
The report shows each section of the unit before and after, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
When to call us in Nettlestead Green
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.
Look out for any of the following:
- Odours coming through the supply air
- Air handling units with blocked filters
- Blocked condensate drains and slimy trays
- Coils clogged with dust and debris
If you manage shops or offices close to Yalding station, a TR19® Air inspection shows whether the ductwork needs cleaning.

Common questions in Nettlestead Green
Can ventilation in schools around Nettlestead Green be cleaned out of term?
Yes, holiday work suits schools best. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Nettlestead Green. Booking early in the term gives the best choice of holiday dates.
Do you work in villages like Nettlestead Green?
Yes, Nettlestead Green is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
Do you need to switch the unit off?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
Can you clean the ducts connected to the AHU?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Is there a survey before the work?
Yes. We always survey first, either from pictures and details you send or on a site visit. Then you get a fixed quote.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
What’s TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.

Managing agents and facilities teams in Nettlestead Green
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Part by part
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
