If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.

How we handle AHU cleaning in Winchfield
Every supply and extract system relies on the air handling unit at its centre: 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. If you have rooms that smell stuffy when the system runs and units that have only ever had filter changes, we can put it right, from filter sections, drain trays and internal panels onwards.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.

Common problems we fix in Winchfield
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
If you notice any of these, it’s worth a diagnosis:
- Dust-coated heating and cooling coils
- Leaves and litter drawn into the unit
- Air handling units never cleaned inside
- Drain trays holding standing water
If you manage offices or shops near Winchfield station, their ventilation can be inspected and cleaned out of hours.

Aftercare tips
So the system stays in good health:
- Report musty smells from the vents right away
- Do not store bins or materials near the intake
- File each AHU report in the maintenance log
- Diary the inspection date recommended in the report
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
Your questions about AHU cleaning in Winchfield
Do you work at weekends in Winchfield?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Just call us on 0345 646 2711, or email photos with your opening times and we will plan around them.
Can you get to a site in Winchfield?
Yes, Winchfield is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
Do you give a certificate after the clean?
Yes. You get a TR19® certificate plus before and after pictures. They’re worth keeping with the plant records.
Do you work with multi-site operators?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
How often do AHUs need cleaning?
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.
What’s included in an AHU clean?
Every section that collects dirt: filters, coils, tray, fan and panels. We confirm the scope after looking at the unit.
Are you fully insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
What the work involves, part by part
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. The intake section gets particular attention.
Why it’s worth doing now in Winchfield
Dirt left in an air handling unit does not stay in the unit. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. Systems in rural buildings are often out of sight and out of mind.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.
