Slough · Air handling unit cleaning
Littleworth Corner AHU cleaning
We cover Littleworth Corner for air handling unit cleaning. Out-of-hours visits, a fixed quote and a written report with pictures as standard.
- Stale or musty smells from the ventilation
- Blocked condensate drains and slimy trays
- Fan sections that haven’t been cleaned in years
Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
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.
About our AHU cleaning in Littleworth Corner
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. If you have units needing a clean before a new tenant or handover and dirty coils holding back the airflow, we can put it right.
For a building in or near Littleworth Corner, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Between visits
After the visit, a few habits help the work last:
- File each AHU report in the maintenance log
- Flag stale or damp smells in the supply air
- Make sure condensate is draining away
- Note any water around the unit or leaks below it
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
Why it’s worth doing now in Littleworth Corner
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. Systems in rural buildings are often out of sight and out of mind.
What you pay depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before work begins, so there are no surprises.

The process
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. Visits to a village like Littleworth Corner are booked in advance, at a time that suits whoever runs the site.
- We survey the unit from pictures or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Mention any sign-in, permit or induction we need
- Clear loose items from the work area

What the work involves, part by part
Filters
Filter condition tells you a lot about the rest of the unit. They’re photographed before and after for your records.
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
