How we handle AHU cleaning in Catherington
We clean air handling units for buildings in Catherington and across Hampshire, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. We are often asked to deal with dirty filters cutting the airflow and stale or musty smells from the ventilation, on internal panels, filter sections and supply and extract fans.
Work in a small place like Catherington starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Think of the report as the system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

What the work involves, part by part
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that won’t bend or flatten the fins.
Catherington: your questions answered
Do you do school ventilation cleaning in Catherington in the summer holidays?
Yes, out-of-term visits are normal for schools. Around Catherington, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
Will you come out to Catherington?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
How much does AHU cleaning cost in Catherington?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote and we will usually reply within one working day.
What types of premises do you cover?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Will we get paperwork for the AHU clean?
Yes. You get a TR19® certificate plus before and after photos. They’re worth keeping with the plant records.
How often should an air handling unit be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
Where does the waste go?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it does not spread.
Does the AHU have to be shut down for cleaning?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
Do you need AHU cleaning in Catherington?
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and that’s where slime and odours start.
If you notice any of these, it’s worth a diagnosis:
- Fan sections that haven’t been cleaned in years
- Air handling units never cleaned inside
- Odours coming through the supply air
- Blocked condensate drains and slimy trays
For schools like Catherington Church of England Infant School, the holidays are the usual time to inspect and clean ventilation.
