Carisbrooke AHU cleaning
AHU cleaning for commercial sites in Carisbrooke and across the Isle of Wight. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.

- Units needing a clean before a new tenant or handover
- Stale or musty smells from the ventilation
About our AHU cleaning in Carisbrooke
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers drain trays, filter sections and supply and extract fans, and the jobs we see most are stale or musty smells from the ventilation and air handling units with blocked filters.
Visits to a place like Carisbrooke are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
The report is your system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

What the work involves, part by part
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that won’t bend or flatten the fins.
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.
Honest limits
A few issues sit outside what this work can do:
- Airflow problems caused by the system’s design
- Problems with the unit’s controls or sensors
- Dirty ducts beyond the unit itself
Not sure which it is? You can call 0345 646 2711 or email us and we will tell you honestly before you book.

Carisbrooke buildings and their air
Food Standards Agency records list about 14 schools, colleges and universities, about 9 caring premises (care homes, nurseries and hospitals) and about 6 hotels, B&Bs and guest houses registered as food businesses in Carisbrooke and the streets around it, up to about 1.5 miles out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. The nearest hospital to Carisbrooke is St Mary's Hospital, about 1.5 miles north-east. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
If you run a surgery, dental practice or care home near Carisbrooke, clean ventilation matters as much to you as to a hospital like St Mary's Hospital (about 1.5 miles north-east).
Carisbrooke is about 1 mile south-west of Newport, in the Isle of Wight. From the centre of Carisbrooke to the outskirts, we cover AHU cleaning for every kind of premises, from a single unit to a large public building.

What’s near Carisbrooke
Around Carisbrooke, our work takes us to kitchens and buildings near Christ The King College, Seaclose Park and Island Innovation VI Form Campus and the streets around them. Nearby you’ll also find Isle of Wight Music Museum (1.1 miles north-east) and Carisbrooke Castle (under half a mile south-east). Open spaces near Carisbrooke include Briddlesford Nature Reserve and Brighstone Down.
Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Look at the condensate drain whenever the unit is serviced
- Keep inspection doors on the unit in good order
- Keep the certificate and photo report with the plant records
- Do not store bins or materials near the intake
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
When to call us in Carisbrooke
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.
What we are most often called out for:
- Leaves and litter drawn into the unit
- Odours coming through the supply air
- Filters that are clogged or overdue
- Units needing a clean before a new tenant or handover
For schools like St Thomas of Canterbury Catholic Primary School, the holidays are the usual time to inspect and clean ventilation.

How it 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. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. In a place like Carisbrooke, we fit the visit around your hours.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Clear loose items from the work area
- Mention any locked doors, roof access or ceiling voids
- Tell us where we can park and unload
Ask for a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Advice
Fixed quotes for AHU cleaning in Carisbrooke
Before we fix a price, we need to know a few things. We check:
- A single visit or a regular plan
- The condition we find in the survey
- How easy every part is to reach
- Whether several sites go on one quote
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
What we need to know
When you contact us, it’s useful to have:
- Any previous report or certificate
- Wide pictures of the system and the area around it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The roof, plant room or outside wall the system runs to
For AHU cleaning in Carisbrooke, ring 0345 646 2711, or email photos. Tell us what kind of premises it is and when it’s open, plus photos or the previous report if they’re to hand. A fixed quote typically follows within one working day.

What else we do in Carisbrooke
In-house cleaning or a specialist?
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Carisbrooke questions
Is Carisbrooke within the area you cover?
Yes, Carisbrooke is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
Do you work at weekends in Carisbrooke?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Let us know the hours you are closed and we’ll book within them.
Do you offer emergency callouts?
Yes. Our emergency line runs 24/7 for anything that can’t wait until a planned visit. Call us any time and explain what’s happened.
Can one contract cover all our sites?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
How much does AHU cleaning cost?
We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before any work starts.
Do you need to switch the unit off?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
Do you repair air handling units?
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.
