AHU cleaning in Elmers End
Our AHU cleans for sites in Elmers End cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after photos in a report. The work covers dampers and louvres, supply and extract fans and filter sections, and the jobs we see most are rooms that smell stuffy when the system runs and dust-coated heating and cooling coils.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. An inspection first shows where cleaning is needed in a building in Elmers End.
Think of the report as the system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Part by part
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Internal casing and panels
We open each section through its doors and close them securely when we are done, and check every one is shut.
What we’re called out for in Elmers End
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. It’s easy for a long time to go by without anyone opening the panels.
Clients usually contact us after spotting one of these:
- Debris and leaves in the fresh air intake
- Dirty filters cutting the airflow
- Dust built up on fan impellers
- Condensate trays that won’t empty
Workplaces around Elmers End station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.

We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further.

- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
How to prepare
- Let us know about permits to work or site inductions
- Make sure equipment near the work can be switched off and left to cool
- Dig out any earlier paperwork for the system

Landlords, agents and facilities managers
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so each one has its own record.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
In-house cleaning or a specialist?
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.

Keeping the system healthy
No system stays clean for ever, but care slows the build-up. A few tips:
- Look at the condensate drain whenever the unit is serviced
- Change filters on schedule and log each change
- Clear leaves and litter away from the intake
- Don’t ignore odours coming through the grilles
Restart the unit with your site team or maintenance contractor once we’ve finished. Check the drain tray is emptying over the first few days to make sure it stays clear.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.

Is parking a problem for work in Elmers End?

What about areas you cannot get to?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Is there a survey before the work?
Yes. We always survey first, from your photos and details, or with a visit where necessary. Then you get a fixed quote.
Can you clean the AHU out of hours?
Yes. The clean is planned around when the unit can be switched off. In hospitals and care homes, we agree timings with the site team.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
What does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we’ll typically reply within one working day.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
