How we handle AHU cleaning in Old Oak Common
We clean air handling units for buildings in Old Oak Common and across Greater London, working to TR19® Air, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. Common call-outs are for dirty coils holding back the airflow and fan sections that haven’t been cleaned in years, across internal panels, dampers and louvres and filter sections.
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. In a building in Old Oak Common, dust and debris build up in the units and ductwork over time.
We’ve been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Staff cleaning versus specialist work
If your staff spot something 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’ll take a look and send you a fixed quote.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
How the job changes from site to site
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
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.

What else we do in Old Oak Common
For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
Records are where multi-site compliance often slips. Each visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
What happens on the day
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Security desks and permits-to-work are routine in London, so let us know what your building in Old Oak Common needs from us.
- We start with a survey of the unit and a fixed quote for the work.
- 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.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after photos.
How to prepare
- Tell us where we can park and unload
- Tell us about site rules, permits or sign-in
- Make sure equipment near the work can be switched off and left to cool

To get a fixed quote, call 0345 646 2711 or email us with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. You’ll normally have a quote within one working day.
Advice
What affects the quote in Old Oak Common
The survey tells us what the work involves. The main factors are:
- The condition of the system
- Whether we need access equipment or extra panels
- A single visit or a regular plan
- How many systems or sites are involved
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
What to send for a quote
When you call or email, these details help:
- The paperwork from the last visit, if you have it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Where the site is and what kind of site it is
- Detail shots of panels, filters and grilles
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price, before we start.
Between visits
Good habits slow the build-up between visits. A few tips:
- Flag stale or damp smells in the supply air
- Change filters on schedule and log each change
- Book the next check in line with the report
- Note any water around the unit or leaks below it
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. Keep both with the building’s maintenance records.
Do not let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.

Leave it or put it right?
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. Choosing the date yourself beats having a fault choose it for you.
What you pay reflects the actual work. That is why we survey first, from photos or on site, and the price is agreed before work begins.
