Acton Vale questions
Can you work in Acton Vale outside opening hours?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Is parking a problem for work in Acton Vale?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
What should I send you?
Some pictures and a quick description of the system, with the address and opening hours. If we need more, we will ask.
Will we get paperwork for the AHU clean?
Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.
What happens to the waste?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
Do you cover Acton Vale?
Yes. We work in Acton Vale and the rest of Greater London, as part of our work across South East England and London. For a fixed quote, give us a ring on 0345 646 2711 or email us.
What’s included in an AHU clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.
How much notice do you need?
Book as early as you can for planned work, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
AHU cleaning in Acton Vale, done properly
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. If you’re dealing with drain trays holding standing water and plant that needs cleaning after a refit, we can put it right.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. In a building in Acton Vale, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.
Think of the report as the system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

The process
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. The visit takes anything from half a day for one small unit to several shifts for a plant room full of them. Most London sites can’t stop for the day, so work in Acton Vale is normally done overnight, early in the morning or at weekends.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Tell us where we can park and unload
- Dig out any earlier paperwork for the system
Getting a quote
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before any work starts.

- Airflow problems caused by the system’s design
- Building management system faults

Keeping the system healthy
After the visit, a few habits help the work last:
- Report stiff or damaged access doors
- Look at the condensate drain whenever the unit is serviced
- Diary the inspection date recommended in the report
- Flag stale or damp smells in the supply air
The report suggests a date for the next inspection or clean, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
Do you need AHU cleaning in Acton Vale?
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
Clients usually contact us when they notice something like this:
- Condensate trays that will not empty
- Air handling units due a clean after building work
- Dirty fans and fan housings
- Dirty filters cutting the airflow
For workplaces around Acton Central station with mechanical ventilation, cleaning can be done in the evening or at weekends.

Why act early in Acton Vale
Standing water in a drain tray does not clear itself. 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. A booked night’s work in Acton Vale costs you no trading time; an unplanned closure does.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we’ll price it together.

In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
What affects the cost of AHU cleaning
The diagnosis comes before the price. We look at:
- Site requirements such as sign-in and permits
- The condition we find in the survey
- The times the site is available
- The size of the system
Every site is different, 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.
Asking for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Photos showing the whole system and its surroundings
- Any symptoms, from odd noises to smells or leaks
- Any previous report or certificate
- Close-ups of filters, grilles, hatches or access panels
For a fixed quote, call 0345 646 2711, or email photos 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 will normally have a quote within one working day.
