AHU cleaning in Temple Fortune
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. The work covers filter sections, dampers and louvres and supply and extract fans, and people most often call us about plant that needs cleaning after a refit and dust built up on fan impellers.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Temple Fortune, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

For landlords and multi-site operators
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
How we price AHU cleaning
The survey tells us what the work involves. We look at:
- Working hours and out-of-hours timing
- Whether we need access equipment or extra panels
- How many systems or sites are involved
- One-off work versus a regular cycle
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
What we need to know
To help us quote quickly, send us:
- Where the site is and what kind of site it is
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Photos showing the whole system and its surroundings
- When the site is open and when it’s quiet
Getting a quote does not take long. Send a few details and pictures, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Keeping the system healthy
Aftercare is simple, and it helps at the next visit:
- Don’t store bins or materials near the intake
- Watch for drips or damp patches near the plant
- Flag stale or damp smells in the supply air
- Stick to the filter change plan
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
Why act early in Temple Fortune
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, particularly where damp has made it stick. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will go through it with you.

Temple Fortune questions
What do you need to know about parking in Temple Fortune?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Working overnight, as we often do in London, typically makes it simpler.
Can ventilation in schools around Temple Fortune be cleaned out of term?
Yes, holiday work suits schools best. With about 50 schools and colleges on the FSA’s register within roughly a mile and a half of Temple Fortune, it pays to plan holiday dates ahead. Just ring 0345 646 2711, or email photos with your term dates and we’ll plan around them.
Do you offer emergency callouts?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
Do you clean the ductwork as well?
Yes. We reach the ducts through access panels, and any sections we cannot reach are noted in the report, and new panels can be fitted.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and we’ll quote them together.
How far ahead should we book?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Will the ventilation be off while you clean?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
What do you clean inside the unit?
Every section that collects dirt: filters, coils, tray, fan and panels. We confirm the scope after looking at the unit.
How the job changes from site to site
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.

Ventilation in Temple Fortune buildings
There are about 50 schools, colleges and universities, about 50 caring premises (care homes, nurseries and hospitals) and about 9 hotels, B&Bs and guest houses on the FSA’s food hygiene register in Temple Fortune and the streets around it, up to about 1.5 miles out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Highgate Private Hospital is the nearest hospital, about 1.9 miles east of Temple Fortune. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. London plant rooms are often on roofs or in basements reached through occupied floors.
If you manage a school such as Garden Suburb Infant School, ventilation cleaning is best booked for the holidays.

How it works
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. Most of the time goes on the work itself, and that takes anything from half a day for one small unit to several shifts for a plant room full of them. Night and weekend working is normal for us in London, and a site in Temple Fortune is no exception.
- 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.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Clear loose items from the work area
- Find the previous report, if there is one
Get a fixed quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
Advice
Common problems we fix in Temple Fortune
Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.
These are the problems we see most often:
- Odours coming through the supply air
- Filters that are clogged or overdue
- Debris and leaves in the fresh air intake
- Air handling units never cleaned inside
If you run a surgery, dental practice or care home near Temple Fortune, clean ventilation matters as much to you as to a hospital like Highgate Private Hospital (about 1.9 miles east).
