How we handle AHU cleaning in Batt's Corner
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. The work covers internal panels, drain trays and supply and extract fans, and the jobs we see most are units needing a clean before a new tenant or handover and dust built up on fan impellers.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
We have been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Aftercare tips
Results last longer with the right care. Here’s what we suggest:
- File each AHU report in the maintenance log
- Look at the condensate drain whenever the unit is serviced
- Do not ignore odours coming through the grilles
- Book the next check in line with the report
We recommend when the unit should next be inspected or cleaned, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Do not let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.

- Ventilation that was badly designed in the first place
- Leaking heating or cooling coils
If you’re not sure, just call 0345 646 2711, or send details by email and we will give you a straight answer before booking.

The process
Each visit runs to the same pattern: protect the area, make the system safe, do the work, tidy up and hand over the paperwork. On site, the work takes from a few hours for a compact unit to a day or more for a large one. If you can send pictures, we can arrive in Batt's Corner knowing what to expect.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- 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.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Before we arrive
- Let us know when the site is closed or quiet
- Arrange a key holder or contact on site
- Mention any locked doors, roof access or ceiling voids

It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.
The symptoms we are asked about most include:
- Filters that are clogged or overdue
- Intake sections clogged with outdoor debris
- Odours coming through the supply air
- Air handling units due a clean after building work

What happens if it’s left?
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. Planning a trip to Batt's Corner ahead is easier for everyone than a rushed one.
