AHU cleaning in Tottenham Green, done properly
Our AHU cleaning covers sites in Tottenham Green and the rest of Greater London, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. We’re often asked to deal with filters that are clogged or overdue and intake sections clogged with outdoor debris, on drain trays, supply and extract fans and dampers and louvres.
Many London buildings have had their ventilation extended and altered through several fit-outs, leaving sections that are hard to reach and seldom cleaned. In Tottenham Green, as elsewhere, cleaning starts with an inspection of what’s there.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Leave it or put it right?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. A building in Tottenham Green may have flats or offices above and alongside, and a fault in the system can affect them too.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.

What a clean won’t put right
A few issues sit outside what this work can do:
- Faulty motors, drives or bearings
- Coils that are corroded or leaking and need replacing
- Ventilation that was badly designed in the first place
If in doubt, call 0345 646 2711, or email photos and we will say what we think.

Looking after it afterwards
How long the results last depends on use and care. We suggest:
- Do not ignore odours coming through the grilles
- Diary the inspection date recommended in the report
- Keep filter changes on time and recorded
- Do not store bins or materials near the intake
When we’ve closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
Common problems we fix in Tottenham Green
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Any of these means the system needs a check-up:
- Air handling units never cleaned inside
- Condensate trays that won’t empty
- Fan sections that haven’t been cleaned in years
- Dust-coated heating and cooling coils
North Middlesex University Hospital, about 1.9 miles north, is the nearest hospital to Tottenham Green, and healthcare sites of every size need their supply air kept clean.

How the visit works
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes from a few hours for a compact unit to a day or more for a large one, and we clear up before we go. In a London area like Tottenham Green, 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 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 pictures and issue the certificate and report.
Preparing for the visit
- Mention any locked doors, roof access or ceiling voids
- Tell us about site rules, permits or sign-in
- Clear loose items from the work area

Can the work in Tottenham Green be done at night or at weekends?

How long will the unit be out of action?
Expect it to take anything from half a day for one small unit to several shifts for a plant room full of them. The unit’s size and condition make the biggest difference, and we’ll confirm the time when we quote.
What happens to the waste?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.
Which parts of an air handling unit do you clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.

Can you fix a faulty AHU?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We will flag anything we notice during the clean.
Is a quote from pictures possible?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Part by part
Drain trays
Drain trays can rust and leak over time. We record their condition with photos so you can decide on any repairs.
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.
Managing agents and facilities teams in Tottenham Green
We also work for facilities teams across offices, schools and healthcare in Tottenham Green and across Greater London. Larger estates can be phased building by building around the people who use them.
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Tottenham Green buildings and their air
There are about 45 schools, colleges and universities and about 42 hospitals, care homes and childcare premises on the FSA’s food hygiene register in and around Tottenham Green, up to about a mile and a half out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. About 1.9 miles north of Tottenham Green is North Middlesex University Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first.
School buildings such as Earlsmead Primary School are normally done in the holidays, so classrooms aren’t disturbed. Workplaces around Seven Sisters station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
