Ickenham AHU cleaning
Cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces for businesses, landlords and public buildings in Ickenham. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- Air handling units never cleaned inside
- Air handling units with blocked filters
- Dust built up on fan impellers
Aftercare tips
Here’s the after-treatment advice, short and simple:
- Flag stale or damp smells in the supply air
- Keep inspection doors on the unit in good order
- Make sure condensate is draining away
- Report water on the plant room floor
Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to make sure it stays clear.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
AHU cleaning in Ickenham
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. Common call-outs are for dirty fans and fan housings and dirty filters cutting the airflow, across dampers and louvres, drain trays and internal panels.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. In a building in Ickenham, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.
Insurers, fire officers and environmental health officers all look at records. 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.

What a clean will not put right
To be straight with you, there are a few things this work will not fix:
- Breakdowns that need a mechanical engineer
- Dirty ducts beyond the unit itself
- Airflow problems caused by the system’s design
If in doubt, phone us on 0345 646 2711 or drop us a line and we will say what we think before booking.
What the work covers
- Heating and cooling coils
- Internal panels
- Filter sections
- Drain trays
- Dampers and louvres
- Supply and extract fans
What the work involves, part by part
Fans and fan sections
Dust on a fan impeller adds weight and wear. A clean fan runs more smoothly.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. Cleaning restores the open path through the fins.
For landlords and multi-site operators
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.

In-house cleaning or a specialist?
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
How we price AHU cleaning
Every site gets its own quote. These are the things that affect it:
- How big the system is
- The number of sites or systems
- Whether we need access equipment or extra panels
- Where the site is and how we reach it
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before we start.

- The site address and the type of premises
- Any access panels or hatches you can see
