AHU cleaning around Flansham
The FSA’s food hygiene register lists about 9 schools, colleges and universities and about 5 hospitals, care homes and childcare premises with registered kitchens or food service in and around Flansham, up to about a mile and a half out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Flansham’s nearest hospital, Bognor Regis War Memorial Hospital, is about 1.7 miles south-west. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. Flansham, about 54 miles from central London, is within our usual area. A survey and a fixed quote come first, then the visit at a time that suits you.
Classrooms and halls at schools such as Bishop Tufnell CofE Primary School are easiest to work in when pupils are away.

About our AHU cleaning in Flansham
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. The work covers heating and cooling coils, supply and extract fans and filter sections, and common reasons people get in touch are rooms that smell stuffy when the system runs and debris and leaves in the fresh air intake.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Each visit ends with a written report and photos, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

For landlords and multi-site operators
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
We also work for facilities teams across offices, schools and healthcare in Flansham and across West Sussex. Larger estates can be phased building by building around the people who use them.

What happens on the day
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes one overnight shift for many single units, with bigger plant phased, and the area is cleaned down before we leave. If the van will struggle with a lane or gateway near Flansham, let us know and we’ll plan around it.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Move anything stored near the system
- Plan for cooking equipment or plant to be off before we arrive
- Find the previous report, if there is one
Ask for a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price, before we start.
Advice
What your team can do, and what needs us
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to 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.
Different parts, different methods
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.
Honest limits
AHU cleaning cannot fix everything, and we will tell you before work begins. It does not solve:
- Controls and BMS settings that run the unit
- Leaking heating or cooling coils
- The supply and extract ducts, quoted separately
If you are not sure, just ring 0345 646 2711 or email us and we’ll give you a straight answer before you book.
What the work covers
- Heating and cooling coils
- Supply and extract fans
- Filter sections
- Dampers and louvres
- Drain trays
- Internal panels
Signs you need AHU cleaning in Flansham
Air handling units are usually tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
Look out for these warning signs:
- Dust built up on fan impellers
- Odours coming through the supply air
- Blocked condensate drains and slimy trays
- Plant that has been serviced but not cleaned
If you run a surgery, dental practice or care home near Flansham, clean ventilation matters as much to you as to a hospital like Bognor Regis War Memorial Hospital (about 1.7 miles south-west).

Common questions in Flansham
Do you cover smaller places like Flansham?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Can you come to Flansham after we close?
Yes, nights and weekends are routine for us. It means the site in Flansham keeps running as normal. When you phone us on 0345 646 2711 or use the quote form, mention when the site is quiet.
Do you offer emergency callouts?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
Do you have insurance?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.
What do you do with what you remove?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
What if parts of the system can’t be reached?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used, and we’ll suggest a schedule and quote for it.
Leave it or put it right?
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. A fault that closes a site in a village like Flansham affects everyone who depends on it.
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before we start.
