Kent · Air handling unit cleaning
Hemsted AHU cleaning
We cover Hemsted for cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces. Out-of-hours visits, a fixed quote and a written report with photos on every job.
- Debris and leaves in the fresh air intake
- Air handling units with blocked filters
- Plant that needs cleaning after a refit
What we do, step by step
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes from a few hours for a compact unit to a day or more for a large one. We agree a date with you, plan the drive to Hemsted and turn up when the site is quiet.
- 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.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Tell us where we can park and unload
- Plan for cooking equipment or plant to be off before we arrive
- Agree a time when the area can be out of use
Getting a quote
Getting a quote does not take long. Send a few details and photos, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

AHU cleaning for kitchens and businesses in Hemsted
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. If you have air handling units due a clean after building work and coils clogged with dust and debris, we can put it right.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, 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.

What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Between visits
A little care between visits keeps the system in better shape. We recommend:
- Keep the certificate and photo report with the plant records
- Clear leaves and litter away from the intake
- Keep filter changes on time and recorded
- Check the drain tray is emptying during routine visits
When we have closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to confirm water is draining away.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
How the job changes from site to site
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. The intake section gets particular attention.
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
What AHU cleaning can’t fix
Some problems need a different service or another trade:
- A system that’s undersized for the building
- Ductwork downstream of the unit, which is a separate clean
- Damaged coils beyond cleaning
If in doubt, ring 0345 646 2711 or email us and we will say what we think before booking.

What we’re called out for in Hemsted
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. Months can pass without anyone looking inside.
Most sites get in touch when they notice something like this:
- Drain trays holding standing water
- Air handling units due a clean after building work
- Dirty filters cutting the airflow
- Units that have only ever had filter changes
Wherever a school like Stowting Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
