- Whether it’s a one-off visit or part of a schedule
- Access, including roofs, risers and ceiling voids

AHU cleaning for kitchens and businesses in Millwall
Heating and cooling coils trap dust that gets past the filters. 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. The work covers drain trays, internal panels and supply and extract fans, and common reasons people get in touch are air handling units due a clean after building work and blocked condensate drains and slimy trays.
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 Millwall, dust and debris build up in the units and ductwork over time.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Keeping the system healthy
Think of this as the after-treatment advice, in brief:
- Report stiff or damaged access doors
- Stick to the filter change plan
- File each AHU report in the maintenance log
- Report water on the plant room floor
The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
Honest limits
AHU cleaning cannot fix everything, and we’d rather say so up front. It won’t put right:
- Ventilation that was badly designed in the first place
- Damaged coils beyond cleaning
- Breakdowns that need a mechanical engineer

Multi-site and managed buildings
From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
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.

Signs you need AHU cleaning in Millwall
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
If you notice any of these, it’s worth a diagnosis:
- Air handling units due a clean after building work
- Plant that has been serviced but not cleaned
- Odours coming through the supply air
- Dirty filters cutting the airflow
Classrooms and halls at schools such as Harbinger Primary School are easiest to work in when pupils are away.

Why act early in Millwall
Stuffy rooms and stale smells in a building in Millwall can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before work begins.

The process
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes half a day to a full day per unit, with large plant planned over several shifts. Before any visit in Millwall, we agree where the van can stop and how equipment reaches the system.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Tell us where we can park and unload
- Make sure equipment near the work can be switched off and left to cool
- Let us know about permits to work or site inductions
