Anything that needs to be off for the work is switched off and left to cool before any work starts, and the area around the work is covered and protected. On site, it takes a single shift for a typical unit, longer for large or heavily soiled ones. Expect the work in Ruislip Gardens to happen after your last customer leaves, not during trading.
- First we agree when the unit can be switched off, including evenings or weekends.

- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.

Getting a quote
Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.

AHU cleaning in Ruislip Gardens, done properly
If the units serving a building in Ruislip Gardens have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. Typical jobs include units needing a clean before a new tenant or handover and coils clogged with dust and debris, on dampers and louvres, supply and extract fans and filter sections.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so work in Ruislip Gardens is often done in the evening or at weekends. Loading and parking are planned with the building first.
The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Signs you need AHU cleaning in Ruislip Gardens
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
These are the problems we see most often:
- Fan sections that haven’t been cleaned in years
- Dirty coils holding back the airflow
- Air handling units with blocked filters
- Leaves and litter drawn into the unit
If you manage shops or offices close to South Ruislip station, a TR19® Air inspection shows whether the ductwork needs cleaning.

What AHU cleaning looks like in Ruislip Gardens
There are about 22 schools, colleges and universities and about 25 care, childcare and hospital premises on the FSA’s food hygiene register across Ruislip Gardens and its immediate surroundings (about a mile and a half). Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. In London, ventilation plant is often on the roof or below ground, so the work is usually done out of hours. For Ruislip Gardens, the closest hospital is Hayes Cottage Hospital, roughly 2.7 miles south. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Wherever a school like Ruislip High School has ducted ventilation, a half-term visit keeps the work out of lesson time. Healthcare ventilation, from large hospitals like Hayes Cottage Hospital (about 2.7 miles south) to small clinics, depends on clean filters, coils and ducts.

What affects the quote in Ruislip Gardens
Sites vary more than people expect. What affects the quote:
- Site requirements such as sign-in and permits
- What state the system is in
- How easy every part is to reach
- A single visit or a regular plan
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.
What to send for a quote
To speed up the quote, please include:
- Your last certificate, test record or report
- Wide pictures of the system and the area around it
- The roof, plant room or outside wall the system runs to
- Close-ups of filters, grilles, hatches or access panels
To get a fixed quote, phone us on 0345 646 2711 or send us an email and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. You’ll normally have a quote within one working day.
Aftercare tips
Here’s the after-treatment advice, short and simple:
- Store the TR19 paperwork where auditors can find it
- Make sure the unit’s access doors open easily
- Diary the inspection date recommended in the report
- Change filters on schedule and log each change
We recommend when the unit should next be inspected or cleaned, 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. Overloaded filters let more dirt through to the coils and fan.
Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Why act early in Ruislip Gardens
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll explain each part.
