About our AHU cleaning in Charing Hill
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. If you have dirty coils holding back the airflow and filters that are clogged or overdue, we can put it right, from filter sections, drain trays and internal panels onwards.
Work in a small place like Charing Hill starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Do you give a certificate after the clean?
Yes. You get a TR19® certificate plus before and after pictures. They’re worth keeping with the plant records.

Charing Hill buildings and their air
At about 43 miles from central London, Charing Hill sits well inside the area we cover. We work evenings, overnight and at weekends, so the visit fits around the site.
School buildings such as Charing Church of England Primary School are usually done in the holidays, so classrooms are not disturbed.

When something else is needed
We’d rather tell you now than book work that will not help, so these are the things it won’t cover:
- Mechanical faults with motors, belts or bearings
- Controls and BMS settings that run the unit
- Airflow problems caused by the system’s design
Not sure which it is? You can call 0345 646 2711 or email us and we will tell you honestly before booking.
What the work covers
- Drain trays
- Dampers and louvres
- Internal panels
- Filter sections
- Supply and extract fans
- Heating and cooling coils
Common problems we fix in Charing Hill
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
If you notice any of these, it’s worth a diagnosis:
- Air handling units never cleaned inside
- Plant that needs cleaning after a refit
- Coils clogged with dust and debris
- Fan sections that haven’t been cleaned in years
If you manage offices or shops near Charing station, their ventilation can be inspected and cleaned out of hours.

What the work involves, part by part
Filters
Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey so the quote reflects it.
Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Change filters on schedule and log each change
- Keep the area around the fresh air intake clear
- Report musty smells from the vents right away
- Look at the condensate drain whenever the unit is serviced
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.

Why deal with it now?
Stuffy rooms and stale smells in a building in Charing Hill can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. It’s worth booking a check, because nobody sees inside a duct day to day.
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, give us a ring on 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.

How the visit works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. The work itself takes half a day to a full day per unit, with large plant planned over several shifts. Photos of the system and how to reach it help us plan a visit to Charing Hill.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Dig out any earlier paperwork for the system
- Clear the space around the work
How to get a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, a few photos and any previous report or certificate. Then phone us on 0345 646 2711 or send us an email.

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 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 are happy to deal with either side, and the report can go to both.
