AHU cleaning for kitchens and businesses in Hockenden
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. The work covers filter sections, heating and cooling coils and dampers and louvres, and common reasons people get in touch are plant that needs cleaning after a refit and units that have only ever had filter changes.
Somewhere as small as Hockenden, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

What your team can do, and what needs us
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
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.
Landlords, agents and facilities managers
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.

Signs you need AHU cleaning in Hockenden
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
It’s time to book a visit if you see:
- Debris and leaves in the fresh air intake
- Filters that are clogged or overdue
- Air handling units never cleaned inside
- Dirty coils holding back the airflow
If you manage a school such as Horizon Primary Academy, ventilation cleaning is best booked for the holidays.
