AHU cleaning for kitchens and businesses in Upper Edmonton
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, which is why we clean the unit itself, not just the ducts. We are often asked to deal with plant that needs cleaning after a refit and intake sections clogged with outdoor debris, across dampers and louvres, internal panels and heating and cooling coils.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. In a building in Upper Edmonton, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.
The report is your system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Common problems we fix in Upper Edmonton
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and some travels further into the unit.
Clients typically contact us after spotting something like this:
- Drain trays holding standing water
- Odours coming through the supply air
- Plant that needs cleaning after a refit
- Dust-coated heating and cooling coils
For workplaces around Silver Street station with mechanical ventilation, cleaning can be done in the evening or at weekends.

Why it’s worth doing now in Upper Edmonton
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before we start.

What we do, step by step
When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. After that, the work takes one overnight shift for many single units, with bigger plant phased. We fit London jobs around the building rather than the other way round, so a visit in Upper Edmonton is normally out of hours.
- We agree a shutdown window that suits the building.
- We take before photos 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.
- We take after pictures and issue the certificate and report.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Mention any sign-in, permit or induction we need
- Mention any parking or loading restrictions
How to get a quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Can you work in Upper Edmonton outside opening hours?

Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.

Is a quote from pictures possible?
Normally, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote usually follows within one working day. If pictures aren’t enough, we will survey first.
Can we book visits on a schedule?
Yes, of course. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.
What should I send you?

AHU cleaning around Upper Edmonton

Busy, occupied buildings like these are where clean supply air matters most. Upper Edmonton’s nearest hospital, North Middlesex University Hospital, is about less than half a mile west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first.
North Middlesex University Hospital, about within half a mile west, is the nearest hospital to Upper Edmonton, and healthcare sites of every size need their supply air kept clean. Wherever a school like St John and St James CofE Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.

Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
