AHU cleaning in Calcott
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. Common call-outs are for drain trays holding standing water and debris and leaves in the fresh air intake, across internal panels, heating and cooling coils and dampers and louvres.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Think of the report as the system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

AHU cleaning in Calcott: local notes
There are about 6 hospitals, care homes and childcare premises on the FSA’s food hygiene register in and around Calcott, up to about a mile and a half out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. We cover Calcott, about 54 miles from central London, as part of our work across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you. For Calcott, the closest hospital is St Martins Hospital, roughly 3.2 miles south. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
For schools like Sturry Church of England Primary School, the holidays are the usual time to inspect and clean ventilation.
Calcott is about 3 miles south of Herne Bay, in Kent.

Our area takes in 922 places across Kent, large and small. Maidstone is in our area too, around 26 miles away.

FAQs for Calcott
Do you work at weekends in Calcott?
Yes. We work evenings, overnight and at weekends. It means the site in Calcott keeps running as normal. Let us know the hours you are closed and we will book within them.
Is Calcott within the area you cover?
Yes. Calcott is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Do you work with multi-site operators?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Every site has its own report.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
Is a quote from pictures possible?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote typically follows within one working day. Some sites still need a visit, and we’ll say so.
Does the AHU have to be shut down for cleaning?
Yes, while the clean is under way. We can work evenings, overnight or at weekends so the building is not left without ventilation when it’s busy.
What does TR19 mean?
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 isn’t law, but it’s the benchmark.
What if parts of the system can’t be reached?
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.
Why act early in Calcott
Dirt left in an air handling unit does not stay in the unit. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. A planned visit to Calcott is easier to arrange than an emergency callout.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will go through it with you.

Other services in Calcott
Different parts, different methods
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.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
How the visit works
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. If you can send pictures, we can arrive in Calcott knowing what to expect.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- 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.
- We close up the unit and send the certificate and before and after pictures.
Before we arrive
- Plan for cooking equipment or plant to be off before we arrive
- Tell us about site rules, permits or sign-in
- Clear the space around the work

Common problems we fix in Calcott
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. So a unit can be well maintained and still dirty.
Keep an eye out for any of the following:
- Air handling units never cleaned inside
- Condensate trays that won’t empty
- Dirty filters cutting the airflow
- Plant that needs cleaning after a refit
Healthcare ventilation, from large hospitals like St Martins Hospital (about 3.2 miles south) to small clinics, depends on clean filters, coils and ducts.
What to look for in a quote
- How areas they can’t reach will be recorded
- How VAT is shown on the quote
- How they set the interval to the next visit
- Whether the work can be done while the site is closed
Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
Honest limits
AHU cleaning cannot fix everything, and we will tell you before we start. It does not solve:
- Mechanical faults with motors, belts or bearings
- Coils that are corroded or leaking and need replacing
- Problems with the unit’s controls or sensors
If in doubt, phone us on 0345 646 2711 or send us an email and we’ll say what we think before you book.

Looking after it afterwards
Here’s the after-treatment advice, short and simple:
- Report water on the plant room floor
- Keep the area around the fresh air intake clear
- Change filters on schedule and log each change
- Check the drain tray is emptying during routine visits
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to make sure it stays clear.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
