Do you need AHU cleaning in Three Ashes?
Filters that are not changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
Common reasons sites call us include:
- Stale or musty smells from the ventilation
- Dust-coated heating and cooling coils
- Air handling units never cleaned inside
- Dirty fans and fan housings
If you manage a school such as Silchester Church of England Primary School, ventilation cleaning is best booked for the holidays.

AHU cleaning for kitchens and businesses in Three Ashes
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. Typical jobs include units needing a clean before a new tenant or handover and condensate trays that won’t empty, across dampers and louvres, drain trays and internal panels.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

FAQs for Three Ashes
Can you clean school ventilation in Three Ashes during the holidays?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 4 schools and colleges with food registrations within roughly a mile and a half of Three Ashes. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Do you cover smaller places like Three Ashes?
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 long does an AHU clean take?
Cleaning takes a single shift for a typical unit, longer for large or heavily soiled ones. Bigger units can be phased, so call 0345 646 2711, or email photos to talk it through.
Do you survey before quoting?
Yes. Every job is surveyed first, from your photos and details, or with a visit where necessary. Then you get a fixed quote.
Do you clean the ductwork as well?
Yes. Ductwork is cleaned through access panels, and any sections we cannot reach are noted in the report, and new panels can be fitted.
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.
When should our AHU next be cleaned?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and the report recommends a next date.
Is there a report after cleaning?
Yes. You get a TR19® certificate plus before and after photos. They’re worth keeping with the plant records.

In-house cleaning or a specialist?
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

For landlords and multi-site operators
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
Aftercare tips
A little care between visits keeps the system in better shape. Our advice:
- Plan the next inspection before the last report gets filed away
- Keep inspection doors on the unit in good order
- Flag stale or damp smells in the supply air
- Keep the certificate and photo report with the plant records
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
How it works
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes anything from half a day for one small unit to several shifts for a plant room full of them, and the area is cleaned down before we leave. Somewhere like Three Ashes, lanes, gates and parking are worth mentioning in advance.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
