AHU cleaning in Hampstead Garden Suburb, done properly
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. The work covers supply and extract fans, drain trays and dampers and louvres, and people most often call us about blocked condensate drains and slimy trays and leaves and litter drawn into the unit.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Hampstead Garden Suburb is typically planned out of hours. Parking and loading are agreed with the building in advance.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
What happens on the day
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. The middle part takes longest, and that takes anything from half a day for one small unit to several shifts for a plant room full of them. If your building in Hampstead Garden Suburb has sign-in rules, permits or key holders, mention them when you book.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Getting ready for the visit
- Clear the space around the work
- Make sure someone can let us in and lock up afterwards
- Tell us about site rules, permits or sign-in

Part by part
Filters
Filter condition tells you a lot about the rest of the unit. They’re photographed before and after for your records.
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Ventilation in Hampstead Garden Suburb buildings
There are about 36 schools, colleges and universities, about 44 caring premises (care homes, nurseries and hospitals) and about 8 hotels and B&Bs on the FSA’s food hygiene register across Hampstead Garden Suburb and its immediate surroundings (about a mile and a half). Buildings like these often rely on mechanical ventilation, which TR19® Air covers. For Hampstead Garden Suburb, the closest hospital is Highgate Private Hospital, roughly 1.3 miles east. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. London plant rooms are often on roofs or in basements reached through occupied floors.
Wherever a school like The Henrietta Barnett School has ducted ventilation, a half-term visit keeps the work out of lesson time.

London parking can be tight, so details of loading bays and permits help. If the building has a loading slot system, we will book into it.
Do you work with multi-site operators?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
Do you survey before quoting?

Where does the waste go?
It leaves the site with us at the end of the visit. While we work, it’s kept contained so the area stays clean.
Do you clean the ductwork as well?
Yes, the ductwork, grilles and diffusers the unit serves. The survey shows whether the ducts need cleaning now.
How much notice should we give?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
