AHU cleaning in Agar Town
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. We are often asked to deal with condensate trays that won’t empty and dirty fans and fan housings, on supply and extract fans, drain trays and filter sections.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Agar Town is normally planned out of hours. Parking and loading are agreed with the building in advance.
Good records are part of the job. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
Why act early in Agar Town
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, especially where there’s been moisture. A booked night’s work in Agar Town costs you no trading time; an unplanned closure does.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.

When to call us in Agar Town
Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
These are the problems we see most often:
- Dust-coated heating and cooling coils
- Fan sections that haven’t been cleaned in years
- Dirty filters cutting the airflow
- Units needing a clean before a new tenant or handover
Healthcare ventilation, from large hospitals like St Pancras Hospital (about less than half a mile south) to small clinics, depends on clean filters, coils and ducts.

Common questions in Agar Town
Can the work in Agar Town be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. That way a site in Agar Town doesn’t have to lose a day’s trading. Just ring 0345 646 2711 or email us with your opening times and we will plan around them.
Is parking a problem for work in Agar Town?
Tell us where a van can stop near your site in Agar Town, and about any building rules on loading. Much of our London work is done overnight, which helps.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’re fully insured and have been trading since 2009.
Is there a survey before the work?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Can you price the work without visiting?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Do you offer maintenance contracts?
Yes, of course. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.
How often should an air handling unit be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.
Part by part
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. Access is planned during the survey, before we quote.
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. In a London area like Agar Town, parking, loading and building access are planned before the day of the work.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Tell us where we can park and unload
- Mention any locked doors, roof access or ceiling voids
- Name a contact who can let us in at the agreed time
