About our AHU cleaning in Rooksdown
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from pictures or on site, followed by a fixed quote, so you know where you stand. We’re often asked to deal with leaves and litter drawn into the unit and dust-coated heating and cooling coils, across heating and cooling coils, supply and extract fans and internal panels.
Around a place like Rooksdown, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

When it’s something else
We won’t sell you work that does not address the problem, so these are the things it won’t cover:
- Leaking heating or cooling coils
- Ductwork downstream of the unit, which is a separate clean
- Airflow problems caused by the system’s design
If in doubt, phone us on 0345 646 2711, or email photos and we’ll say what we think.

When to call us in Rooksdown
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, a little more each month.
Keep an eye out for any of the following:
- Dirty fans and fan housings
- Rooms that smell stuffy when the system runs
- Intake sections clogged with outdoor debris
- Coils clogged with dust and debris
For schools like Fort Hill Community School, the holidays are the usual time to inspect and clean ventilation.
Questions to ask before you book
- Whether the figure could change on the day
- Whether a survey comes first
- Which accreditations they hold, and whether you can check them
- When the next visit should be, and why
Rooksdown: your questions answered
Will you come out to Rooksdown?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Do you do school ventilation cleaning in Rooksdown in the summer holidays?
Yes, holiday work suits schools best. With about 9 schools and colleges on the FSA’s register within roughly a mile and a half of Rooksdown, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
How long will the unit be out of action?
Typically the clean takes half a day to a full day per unit, with large plant planned over several shifts. We plan the shutdown around that, including evenings or weekends.
Can you clean without disrupting the building?
Yes. We time the work to fit the building’s hours. Healthcare and care settings are planned with staff.
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 we will suggest an interval after the first clean.
Does the AHU have to be shut down for cleaning?
Yes, while the clean is under way. Out-of-hours work is available to keep disruption down.
How much notice do you need?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Can one contract cover all our sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
Rooksdown buildings and their air
There are about 9 schools, colleges and universities and about 15 care, childcare and hospital premises on the FSA’s food hygiene register across Rooksdown and its immediate surroundings (about a mile and a half). Busy, occupied buildings like these are where clean supply air matters most. About 47 miles out from central London, Rooksdown is part of the South East area we work across. Evening, overnight and weekend visits are all possible. About within half a mile south of Rooksdown is Park Prewett Hospital, the nearest hospital. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
Healthcare ventilation, from large hospitals like Park Prewett Hospital (about less than half a mile south) to small clinics, depends on clean filters, coils and ducts.
Rooksdown is about 1 mile north-west of Basingstoke, in Hampshire. Anywhere in RG24, we can take on AHU cleaning. Across Hampshire, we cover 683 places, and Rooksdown is one of them. We also work in Reading, about 13 miles from Rooksdown.
All of RG24, RG23 and RG26 is covered for AHU cleaning, from busy streets to back roads. AHU cleaning is available to premises on Mill Road, The Square and Hasket Road and nearby roads. If your site is just outside Rooksdown, we cover Winklebury (1 mile south), Sherborne St John (1 mile north-east), Basingstoke (1 mile south-east), Worting (2 miles south-west) and Buckskin (2 miles south). We also work in nearby towns such as Farnborough (15 miles east), Fleet (12 miles east), Alton (11 miles south-east), Yateley (13 miles east), Tadley (5 miles north) and Hook (7 miles east).
What’s near Rooksdown
We work in commercial kitchens and buildings around Winklebury Infant School, among other places. For rail, the closest station is Basingstoke station, roughly 1.7 miles south-east of the centre. Nearby you will also find Willis Museum (1.9 miles south-east) and Park Prewett Hospital (within half a mile south). Not far away are Farleigh Hill and Daneshill Park Woods.
What happens if it’s left?
Leave an AHU uncleaned and the dirt doesn’t stay put. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. A site near Rooksdown that has to close at short notice is hard to cover for.
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, call 0345 646 2711 or send us an email and we will give you an honest view and a fixed quote.

Staff cleaning versus specialist work
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. Cleaning inside ducts and units is specialist work.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
How the visit works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes one overnight shift for many single units, with bigger plant phased. Tell us when your site near Rooksdown is quiet and the visit will be booked for then.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about permits to work or site inductions
Getting a quote
We don’t publish a price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To get going, give us a ring on 0345 646 2711 or email us.

Part by part
Drain trays
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
Keeping the system healthy
After the visit, a few habits help the work last:
- Don’t store bins or materials near the intake
- File each AHU report in the maintenance log
- Change filters on schedule and log each change
- Book the next check in line with the report
Stick to the filter change schedule, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
