AHU cleaning in St Ann's Green
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. We’re often asked to deal with units that have only ever had filter changes and dust-coated heating and cooling coils, on internal panels, supply and extract fans and drain trays.
For a building in or near St Ann's Green, access is agreed in advance and the visit is planned around the journey.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

How it works
Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. If the van will struggle with a lane or gateway near St Ann's Green, let us know and we’ll plan around it.
- We survey the unit from photos or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Clear loose items from the work area
- Make sure equipment near the work can be switched off and left to cool
- Let us know when the site is closed or quiet

What your team can do, and what needs us
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
Between visits
So the system stays in good health:
- Stick to the filter change plan
- Flag stale or damp smells in the supply air
- Report stiff or damaged access doors
- Do not store bins or materials near the intake
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can survey both.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
Landlords, agents and facilities managers
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Where a tenant occupies the premises but the landlord owns the building, 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 St Ann's Green
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. Rural sites can’t always move to another kitchen or room when something fails.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before work begins.

Part by part
Internal casing and panels
We open each section through its doors and close them securely when we’re done before the unit is handed back.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.
