- Dirty ducts beyond the unit itself
- Faulty motors, drives or bearings
- Coils that are corroded or leaking and need replacing
If in doubt, ring 0345 646 2711, or email photos and we’ll say what we think.

AHU cleaning in The Hyde, done properly
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. If you are dealing with dust built up on fan impellers and dirty coils holding back the airflow, we can put it right.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. In a building in The Hyde, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. We clean the impeller, housing and surrounding section.
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
Leave it or put it right?
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. Every month a London system goes without attention adds to what has to be done later.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.

In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
What happens on the day
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes half a day to a full day per unit, with large plant planned over several shifts. In a London area like The Hyde, parking, loading and building access are planned before the day of the work.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Move anything stored near the system
- Make sure equipment near the work can be switched off and left to cool

What affects the cost of AHU cleaning
Every site gets its own quote. These are the things that affect it:
- A single visit or a regular plan
- What state the system is in
- Any permits to work or inductions
- The scale of the work
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, ring 0345 646 2711, or email photos for straight advice and a fixed quote.
Helping us quote
You don’t need the technical terms. Just send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Detail shots of panels, filters and grilles
- Your last certificate, test record or report
- When the site is open and when it’s quiet
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before work begins.
AHU cleaning around The Hyde
Food Standards Agency data includes about 39 schools, colleges and universities and about 48 caring premises (care homes, nurseries and hospitals) within about 1.5 miles of central The Hyde. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. The Hyde’s nearest hospital, St Andrew's Hospital, is about 1.5 miles south-east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. Getting kit to a London plant room usually means lifts, stairs and an agreed loading slot.
Hospitals such as St Andrew's Hospital (about 1.5 miles south-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near The Hyde are no different. If you manage a school such as The Hyde School, ventilation cleaning is best booked for the holidays. If you run an office near Hendon station, its supply ductwork can gather dust for years before anyone looks inside.

What’s near The Hyde
Locally, jobs take us to businesses close to Moon Under Water pub, Brampton College and West Hendon Playing Fields, among other places. There’s a railway station in The Hyde itself: Hendon station. A little further out are St Andrew's Hospital (1.5 miles south-east) and Church Farmhouse Museum (1.1 miles north-east). Open spaces near The Hyde include Parliament Hill and Darland's Lake.
Looking after it afterwards
Here’s the after-treatment advice, short and simple:
- Make sure condensate is draining away
- Report water on the plant room floor
- Store the TR19 paperwork where auditors can find it
- Change filters on schedule and log each change
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can survey both.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
