About our AHU cleaning in West Ealing
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. The work covers heating and cooling coils, internal panels and dampers and louvres, and people most often call us about dirty coils holding back the airflow and stale or musty smells from the ventilation.
London buildings tend to keep their plant on the roof or below ground, so work in West Ealing is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Common problems we fix in West Ealing
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:
- Plant that needs cleaning after a refit
- Air handling units never cleaned inside
- Stale or musty smells from the ventilation
- Condensate trays that will not empty
For workplaces around Hanwell station with mechanical ventilation, cleaning can be done in the evening or at weekends.

What staff can safely do
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Do not ignore odours coming through the grilles
- Book the next check in line with the report
- Keep the area around the fresh air intake clear
- Watch for drips or damp patches near the plant
When we’ve closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
How we price AHU cleaning
There’s no set price list, because no two systems are the same. What we look at:
- How easy every part is to reach
- Parking and loading at the site
- Whether several sites go on one quote
- Site requirements such as sign-in and permits
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before we start.
What we need to know
A few details help us quote accurately. With your enquiry, please include:
- Photos showing the whole system and its surroundings
- Where the site is and what kind of site it is
- The roof, plant room or outside wall the system runs to
- Your last certificate, test record or report

What happens on the day
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes one overnight shift for many single units, with bigger plant phased. A name and number for whoever controls access to the building in West Ealing saves time on the night.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- 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.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Clear the space around the work
- Mention any locked doors, roof access or ceiling voids

For landlords and multi-site operators
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so each one has its own record.
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 send the paperwork to whoever needs it.
