Bassett buildings and their air
Going by the FSA’s register, there are about 25 schools, colleges and universities, about 29 care, childcare and hospital premises and about 5 hotels and B&Bs serving food within roughly a mile and a half of the centre of Bassett. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. For Bassett, the closest hospital is Princess Anne Hospital, roughly 1.1 miles west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
School buildings such as Cantell School are typically done in the holidays, so classrooms aren’t disturbed.

AHU cleaning in Bassett
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. Typical jobs include drain trays holding standing water and units needing a clean before a new tenant or handover, on supply and extract fans, internal panels and dampers and louvres.
Visits to a place like Bassett are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
A written report with pictures follows every visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

The process
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes half a day to a full day per unit, with large plant planned over several shifts, and the area is cleaned down before we leave. For a site near Bassett, the work is booked around your opening hours, evenings and weekends included.
- 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 photos and issue the certificate and report.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Clear loose items from the work area
- Name a contact who can let us in at the agreed time

FAQs for Bassett
Do you work at weekends in Bassett?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Just ring 0345 646 2711 or email us with your opening times and we’ll plan around them.
Do you work in villages like Bassett?
Yes. Villages and rural sites across the South East are part of our work, Bassett included. Photos of the system and directions to the site help us plan the visit.
Can you fix a faulty AHU?
We clean the unit and flag faults rather than repair them, with the details in the report.
Can you clean the ducts connected to the AHU?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
What do you do to protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
Do you look at the system first?
Yes. We always survey first, from your photos and details, or with a visit where needed. A fixed quote follows.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.
Different parts, different methods
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
Drain trays
The drain tray collects water from the cooling coil. Standing water and slime are removed and the outlet is checked.
Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Report water on the plant room floor
- Keep the area around the fresh air intake clear
- Diary the inspection date recommended in the report
- Report stiff or damaged access doors
When we have closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
Other services in Bassett
Common problems we fix in Bassett
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
Keep an eye out for any of the following:
- Plant that has been serviced but not cleaned
- Coils clogged with dust and debris
- Drain trays holding standing water
- Air handling units with blocked filters
If you run a surgery, dental practice or care home near Bassett, clean ventilation matters as much to you as to a hospital like Princess Anne Hospital (about 1.1 miles west).
What to look for in a quote
- How they set the interval to the next visit
- Exactly which parts of the system are covered
- Proof of accreditation you can verify
- Proof of insurance
Leave it or put it right?
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. Booking now means the visit to Bassett is planned around you, not forced by a breakdown.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, ring 0345 646 2711 or use the quote form for straight advice and a fixed quote.
