How we handle AHU cleaning in Chelsfield
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. The work covers dampers and louvres, supply and extract fans and heating and cooling coils, and people most often call us about air handling units due a clean after building work and air handling units never cleaned inside.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. In a building in Chelsfield, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.
The paperwork matters as much as the work. You get a written report with pictures after every visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

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, alongside our reports.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
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’re happy to deal with either side, and the report can go to both.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.
Questions from Chelsfield
Can parking be tricky for a job in Chelsfield?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Working overnight, as we often do in London, normally makes it simpler.
Can ventilation in schools around Chelsfield be cleaned out of term?
Yes. The holidays are the usual time for school work. Around Chelsfield, the Food Standards Agency lists about 3 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
Is there a report after cleaning?
Yes. A TR19® certificate and photo report are sent after the clean, with any faults we noticed.
What do you do to protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Can you look after several sites?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
Can you clean the AHU out of hours?
Yes. The clean is planned around when the unit can be switched off. Healthcare and care settings are planned with staff.
Will you repair the fan or motor?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report for your maintenance team to follow up.
Do you work in Chelsfield?
Yes. Chelsfield is part of the area we cover, within the South East and London area we cover.
Why it’s worth doing now in Chelsfield
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. Choosing the date yourself beats having a fault choose it for you.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, call us on 0345 646 2711 or email us and we will give you an honest view and a fixed quote.

Part by part
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
