- Plant that has been serviced but not cleaned

The process
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. A name and number for whoever controls access to the building in Kingsbury saves time on the night.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Name a contact who can let us in at the agreed time
- Let us know how we reach the system, including roofs, risers and plant rooms

AHU cleaning in Kingsbury, done properly
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 dampers and louvres, internal panels and heating and cooling coils, and common reasons people get in touch are rooms that smell stuffy when the system runs and filters that are clogged or overdue.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. In Kingsbury, as elsewhere, cleaning starts with an inspection of what’s there.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

How the job changes from site to site
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Drain trays
Drain trays can rust and leak over time. We record their condition with pictures so you can decide on any repairs.
Kingsbury: your questions answered
Can you clean school ventilation in Kingsbury during the holidays?
Yes, out-of-term visits are normal for schools. There are about 30 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Kingsbury. You can ring 0345 646 2711 or drop us a line with the dates the site is empty.
Is parking a problem for work in Kingsbury?
London parking can be tight, so details of loading bays and permits help. Where restrictions apply in the day, an evening or overnight visit usually gets round them.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
How do you keep the site clean during the work?
By covering it before any work starts. The work is kept contained and leave the area clean.
Do you work evenings or weekends?
Yes. Evening, overnight and weekend work is all possible, so offices, schools and shops can carry on.
How long will the unit be out of action?
As a guide, it takes anything from half a day for one small unit to several shifts for a plant room full of them. We plan the shutdown around that, out of hours if needed.
Do you survey before quoting?
Yes. We always survey first, from your pictures and details, or with a visit where necessary. Then you get a fixed quote.
Do you work with multi-site operators?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Every site has its own report.
What your team can do, and what needs us
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, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Signs you need AHU cleaning in Kingsbury
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.
Any of these means the system needs a check-up:
- Plant that has been serviced but not cleaned
- Filters that are clogged or overdue
- Drain trays holding standing water
- Leaves and litter drawn into the unit
Edgware Community Hospital, about 1.6 miles north, is the nearest hospital to Kingsbury, and healthcare sites of every size need their supply air kept clean.
What to look for in a quote
- What insurance they carry
- Exactly which parts of the system are covered
- Whether they recommend a next date
- Whether inaccessible sections are listed on the report
Ventilation in Kingsbury buildings
Food Standards Agency data includes about 30 schools, colleges and universities, about 53 care, childcare and hospital premises and about 3 hotels and B&Bs in and around Kingsbury, up to about a mile and a half out. Busy, occupied buildings like these are where clean supply air matters most. Getting kit to a London plant room typically means lifts, stairs and an agreed loading slot. Kingsbury’s nearest hospital, Edgware Community Hospital, is about 1.6 miles north. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
Classrooms and halls at schools such as Kingsbury Green Primary School are easiest to work in when pupils are away.

Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Plan the next inspection before the last report gets filed away
- Note any water around the unit or leaks below it
- Don’t ignore odours coming through the grilles
- File each AHU report in the maintenance log
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
What happens if it’s left?
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. It’s better booked as a planned job in Kingsbury than handled as an emergency.
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before work begins.
