AHU cleaning for kitchens and businesses in West Norwood
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. The work covers dampers and louvres, internal panels and drain trays, and common reasons people get in touch are units that have only ever had filter changes and intake sections clogged with outdoor debris.
London buildings tend to keep their plant on the roof or below ground, so work in West Norwood is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
The report is your system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

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
Dust on a fan impeller adds weight and wear. A clean fan runs more smoothly.
What AHU cleaning looks like in West Norwood
The FSA’s food hygiene register lists about 42 schools, colleges and universities, about 74 care, childcare and hospital premises and about 3 hotels, B&Bs and guest houses with registered kitchens or food service within about 1.5 miles of central West Norwood. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. About 1.6 miles east of West Norwood is St Christopher's Hospice, the nearest hospital.

Hospitals such as St Christopher's Hospice (about 1.6 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near West Norwood are no different.

The process
Each visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, do the work, tidy up and leave you the report. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. A name and number for whoever controls access to the building in West Norwood saves time on the night.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Dig out any earlier paperwork for the system
- Plan for cooking equipment or plant to be off before we arrive
- Clear the space around the work
How to get a quote
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

FAQs for West Norwood
Can you clean school ventilation in West Norwood during the holidays?
Yes. The holidays are the usual time for school work. Around West Norwood, the Food Standards Agency lists about 42 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
Do you work at weekends in West Norwood?

What accreditations do you have?
Duct Doctor is 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.
Do you have a 24/7 line?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
Do you do ventilation duct cleaning too?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can quote for both.
What happens to the waste?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Each site gets its own report and pictures.
What we are called out for in West Norwood
Filters that are not changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
Look out for these warning signs:
- Air handling units never cleaned inside
- Odours coming through the supply air
- Intake sections clogged with outdoor debris
- Dust-coated heating and cooling coils
School buildings such as St Luke's Church of England Primary School are typically done in the holidays, so classrooms aren’t disturbed.
