AHU cleaning in Greengate
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. Common call-outs are for dirty coils holding back the airflow and filters that are clogged or overdue, on supply and extract fans, heating and cooling coils and dampers and louvres.
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. For a building in Greengate, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
The paperwork matters as much as the work. You get a written report with pictures after each 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.

Why it’s worth doing now in Greengate
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that doesn’t feel as comfortable, and a planned clean is far less disruptive than a breakdown. It’s better booked as a planned job in Greengate than handled as an emergency.
The cost depends on the size of the system, the condition it’s in and access to every part of it. We give you a fixed price before any work starts, so you know where you stand.

AHU cleaning in Greengate: local notes
Food Standards Agency data includes about 65 schools, colleges and universities, about 51 hospitals, care homes and childcare premises and about 19 hotels and B&Bs within roughly a mile and a half of the centre of Greengate. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Greengate’s nearest hospital, Newham University Hospital, is about 0.5 miles south-east. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. Getting kit to a London plant room usually means lifts, stairs and an agreed loading slot.
For schools like Southern Road Primary School, the holidays are the usual time to inspect and clean ventilation.

Part by part
Internal casing and panels
Dust settles on every internal surface of the unit. Each section is cleaned from the intake through to the outlet.
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
Do you need AHU cleaning in Greengate?
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Signs it’s time to call us include:
- Fan sections that haven’t been cleaned in years
- Blocked condensate drains and slimy trays
- Intake sections clogged with outdoor debris
- Air handling units due a clean after building work
Hospitals such as Newham University Hospital (about 0.5 miles south-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Greengate are no different.

Do you clean school ventilation in Greengate in the holidays?
Yes. Half-terms and the summer break are the natural time for school work.

What do you do with what you remove?
It leaves the site with us at the end of the visit. While we work, it’s kept contained to keep the area clean.
How often should an air handling unit be cleaned?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.

What happens on the day
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes half a day to a full day per unit, with large plant planned over several shifts. Expect the work in Greengate to happen after your last customer leaves, not during trading.
- We survey the unit from pictures or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after pictures.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Let us know about parking and loading
- Allow time for equipment near the work to be turned off and cool down
Ask for a quote
Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.
Advice
Looking after it afterwards
Simple habits between visits make a real difference. We recommend:
- Plan the next inspection before the last report gets filed away
- Report stiff or damaged access doors
- Report musty smells from the vents straight away
- Note any water around the unit or leaks below it
Restart the unit with your site team or maintenance contractor once we’ve finished. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
