Ventilation in Cliddesden buildings
Food Standards Agency records list about 9 schools, colleges and universities, about 9 hospitals, care homes and childcare premises and about 3 hotels and B&Bs registered as food businesses in and around Cliddesden, up to about a mile and a half out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. The nearest hospital to Cliddesden is Basingstoke and North Hampshire Hospital, about 3 miles north. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. Cliddesden, about 47 miles from central London, is within our usual area. Visits are booked around your hours, evenings and weekends included.
Wherever a school like Cliddesden Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

About our AHU cleaning in Cliddesden
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. If you’re dealing with air handling units due a clean after building work and intake sections clogged with outdoor debris, we can put it right.
Work in a small place like Cliddesden starts with agreeing access and timings.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Questions from Cliddesden
Can a school’s ventilation in Cliddesden be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. Around Cliddesden, the Food Standards Agency lists about 9 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you call 0345 646 2711 or use the quote form, and we’ll fit the work in.
Do you work in villages like Cliddesden?
Yes, we work in villages as well as towns, and Cliddesden is covered. The journey is planned ahead, so a few details about the route help.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
Is a quote from pictures possible?
Yes, where the pictures show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
Are you insured?
Yes. We are fully insured, and we can share the details when you need them.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line, for problems that cannot wait. Call us any time and explain what’s happened.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
Honest limits
We will always give you a straight diagnosis, so here’s what AHU cleaning won’t do:
- Coils that are corroded or leaking and need replacing
- Problems with the unit’s controls or sensors
- Breakdowns that need a mechanical engineer
If in doubt, call us on 0345 646 2711 or send us an email and we will say what we think.
Where we work

Leave it or put it right?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. Our certificate and photo report give you clear evidence, ready to show anyone who asks. With notice, the visit to Cliddesden can be fitted around your bookings and events.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, call 0345 646 2711, or email photos for straight advice and a fixed quote.

Do you need AHU cleaning in Cliddesden?
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that’s the air they breathe for hours on end.
Most sites get in touch after spotting something like this:
- Filters that are clogged or overdue
- Leaves and litter drawn into the unit
- Plant that has been serviced but not cleaned
- Condensate trays that will not empty
Healthcare buildings such as Basingstoke and North Hampshire Hospital, about 3 miles north, depend on their ventilation; if you manage a surgery, clinic or care home near Cliddesden, yours matters too.
What your quote should include
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Proof of insurance
- How they set the interval to the next visit
- What records you’ll receive afterwards
How the visit works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. On site, it takes from a few hours for a compact unit to a day or more for a large one. In a small place like Cliddesden, the journey is planned ahead and the visit arranged around the site’s hours.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Getting ready for the visit
- Agree a time when the area can be out of use
- Dig out any earlier paperwork for the system
- Make sure someone can let us in and lock up afterwards

Looking after it afterwards
How long the results last depends on use and care. We suggest:
- Report stiff or damaged access doors
- Change filters on schedule and log each change
- Plan the next inspection before the last report gets filed away
- Keep the area around the fresh air intake clear
The report shows each section of the unit before and after, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
How the job changes from site to site
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. Cleaning restores the open path through the fins.
