About our AHU cleaning in Finkley Down
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. If you’re dealing with leaves and litter drawn into the unit and units needing a clean before a new tenant or handover, we can help, from heating and cooling coils, supply and extract fans and drain trays 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’ve 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 carry full insurance.

- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- 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.

Finkley Down buildings and their air
Going by the FSA’s register, there are about 5 schools, colleges and universities and about 11 care, childcare and hospital premises serving food within about 1.5 miles of central Finkley Down. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Andover War Memorial Hospital is the nearest hospital, about 2.1 miles west of Finkley Down. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Healthcare ventilation, from large hospitals like Andover War Memorial Hospital (about 2.1 miles west) to small clinics, depends on clean filters, coils and ducts. Wherever a school like Vigo Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
Your questions about AHU cleaning in Finkley Down
Can ventilation in schools around Finkley Down be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. With about 5 schools and colleges on the FSA’s register within roughly a mile and a half of Finkley Down, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can you come to Finkley Down after we close?
Yes. We work evenings, overnight and at weekends. It means the site in Finkley Down keeps running as normal. Just phone us on 0345 646 2711, or send details by email with your opening times and we will plan around them.
Can you come out in an emergency?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we’ll advise on what to do next.
Do you work in Finkley Down?
Yes. Our technicians work in Finkley Down, as part of our area across London and the South East.
When should our AHU next be cleaned?
That’s set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
Which accreditations do you hold?
We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
How long will the unit be out of action?
The work takes half a day to a full day per unit, with large plant planned over several shifts. Large plant can be split over several shifts, so call 0345 646 2711 or email us to talk it through.
What the work involves, part by part
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated with your site team.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins aren’t damaged.
Leave it or put it right?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, ready to show anyone who asks. Equipment tucked in a roof space or outbuilding near Finkley Down rarely gets looked at unless someone books it.
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 explain each part.

Looking after it afterwards
Good habits slow the build-up between visits. Our tips:
- Flag stale or damp smells in the supply air
- Clear leaves and litter away from the intake
- Make sure condensate is draining away
- Plan the next inspection before the last report gets filed away
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
Multi-site and managed buildings
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Honest limits
AHU cleaning can’t fix everything, and we’d rather say so up front. It does not solve:
- Ventilation that was badly designed in the first place
- Leaking heating or cooling coils
- Ductwork downstream of the unit, which is a separate clean
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we will tell you honestly before booking.
