- Internal panels
- Drain trays
- Supply and extract fans
- Heating and cooling coils
How we handle AHU cleaning in Fishbourne
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’re dealing with plant that has been serviced but not cleaned and dirty coils holding back the airflow, we can help, from drain trays, dampers and louvres and filter sections onwards.
Smaller buildings around Fishbourne often keep their ventilation units in a roof void or plant cupboard, where they’re easy to forget. Filters, coils and drain trays need attention whatever the size of the unit.
The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

We work evenings, overnight and at weekends, so the visit fits around the site. For Fishbourne, the closest hospital is St Richard's Hospital, roughly 1.9 miles east. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
Classrooms and halls at schools such as Fishbourne CofE Primary School are easiest to work in when pupils are away. Healthcare ventilation, from large hospitals like St Richard's Hospital (about 1.9 miles east) to small clinics, depends on clean filters, coils and ducts.

Fishbourne: your questions answered
Can a school’s ventilation in Fishbourne be done out of term time?
Yes. The holidays are the usual time for school work. With about 15 schools and colleges on the FSA’s register within roughly a mile and a half of Fishbourne, it pays to plan holiday dates ahead. Send us your term dates when you call us on 0345 646 2711 or drop us a line, and we will fit the work in.
Can you come to Fishbourne after we close?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Fishbourne needn’t be disturbed. Your opening times are the first thing we ask for.
Will you repair the fan or motor?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report for your maintenance team to follow up.
Are you insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
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.
Do you do ventilation duct cleaning too?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can quote for both.
How long does an AHU clean take?
As a guide, it takes a single shift for a typical unit, longer for large or heavily soiled ones. The shutdown is planned to fit, out of hours if needed.
Will the ventilation be off while you clean?
Yes, for the time we’re working on it. Out-of-hours work is available to keep disruption down.
What the work involves, part by part
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.
How it works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes anything from half a day for one small unit to several shifts for a plant room full of them. We plan the journey to Fishbourne and bring what the job is likely to need.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Before we arrive
- Name a contact who can let us in at the agreed time
- Dig out any earlier paperwork for the system
- Allow time for equipment near the work to be turned off and cool down
Get a fixed quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

In-house cleaning or a specialist?
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, alongside our reports.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
Leave it or put it right?
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. A quieter site near Fishbourne still needs its system looked after.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will go through it with you.
What you get with us
- Photo reports with every job
- CHAS, SafeContractor and ISO 9001
- Evenings, overnight and weekends, plus 24/7 emergency callout
- We are fully insured
Between visits
No system stays clean for ever, but care slows the build-up. A few tips:
- Report stiff or damaged access doors
- Store the TR19 paperwork where auditors can find it
- Clear leaves and litter away from the intake
- Keep filter changes on time and recorded
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
What we are called out for in Fishbourne
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
Common reasons sites call us include:
- Dirty coils holding back the airflow
- Air handling units due a clean after building work
- Filters that are clogged or overdue
- Units that have only ever had filter changes
If you run an office near Fishbourne station, its supply ductwork can gather dust for years before anyone looks inside.
