South Tottenham buildings and their air
Food Standards Agency records list about 45 schools, colleges and universities and about 42 hospitals, care homes and childcare premises registered as food businesses within about 1.5 miles of central South Tottenham. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. For South Tottenham, the closest hospital is North Middlesex University Hospital, roughly 2 miles north. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first.
If you manage a school such as Earlsmead Primary School, ventilation cleaning is best booked for the holidays. North Middlesex University Hospital, about 2 miles north, is the nearest hospital to South Tottenham, and healthcare sites of every size need their supply air kept clean.

About our AHU cleaning in South Tottenham
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. The work covers dampers and louvres, supply and extract fans and internal panels, and common reasons people get in touch are fan sections that haven’t been cleaned in years and air handling units with blocked filters.
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 South Tottenham, dust settles in the units and ducts year after year.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

South Tottenham: your questions answered
Do you clean school ventilation in South Tottenham in the holidays?
Yes, and it’s the easiest time to do it. With about 45 schools and colleges on the FSA’s register within roughly a mile and a half of South Tottenham, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
How do you handle parking and loading in South Tottenham?
Tell us where a van can stop near your site in South Tottenham, and about any building rules on loading. Working overnight, as we often do in London, typically makes it simpler.
What’s included in an AHU clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
Do you repair air handling units?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We will flag anything we notice during the clean.
Can you look after several sites?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.

Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.

Why it’s worth doing now in South Tottenham
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. In South Tottenham, a planned overnight visit is much easier than closing unexpectedly.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll go through it with you.

To be straight with you, some problems need a different fix:
- Airflow problems caused by the system’s design
- Leaking heating or cooling coils
- Problems with the unit’s controls or sensors
If in doubt, phone us on 0345 646 2711 or send us an email and we’ll say what we think.
What the work covers
- Filter sections
- Supply and extract fans
- Drain trays
- Heating and cooling coils
- Dampers and louvres
- Internal panels
Signs you need AHU cleaning in South Tottenham
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Clients usually contact us after spotting something like this:
- Odours coming through the supply air
- Intake sections clogged with outdoor debris
- Air handling units due a clean after building work
- Dirty filters cutting the airflow
If you manage shops or offices close to Seven Sisters station, a TR19® Air inspection shows whether the ductwork needs cleaning.

Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
What we do, step by step
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes from a few hours for a compact unit to a day or more for a large one. In a London area like South Tottenham, parking, loading and building access are planned before the day of the work.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know when the site is closed or quiet
How to get a quote

Aftercare tips
Looking after the system between visits is straightforward, and it helps at the next visit:
- Keep the certificate and photo report with the plant records
- Make sure the unit’s access doors open easily
- Don’t ignore odours coming through the grilles
- Look at the condensate drain whenever the unit is serviced
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
How the job changes from site to site
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey so the quote reflects it.
Internal casing and panels
We open each section through its doors and close them securely when we’re done before the unit is handed back.
