AHU cleaning in Welborne
Our AHU cleaning covers sites in Welborne and the rest of Hampshire, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. Common call-outs are for leaves and litter drawn into the unit and dirty coils holding back the airflow, across internal panels, dampers and louvres and filter sections.
In a village or hamlet like Welborne, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Good records are part of the job. You get a written report with photos after each visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Welborne buildings and their air
Going by the FSA’s register, there are about 7 caring premises (care homes, nurseries and hospitals) serving food within roughly a mile and a half of the centre of Welborne. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. The nearest hospital to Welborne is Knowle Hospital, about 0.5 miles west. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
If you manage a school such as The Henry Cort Community College, ventilation cleaning is best booked for the holidays.

Part by part
Drain trays
Standing water in a tray sits right where the air passes. We clean it and report anything about the tray or drain that needs fixing.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that will not bend or flatten the fins.
The process
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. A quick note on how to find the site and where to park makes a visit to Welborne run smoothly.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after pictures.
Before we arrive
- Find the previous report, if there is one
- Mention any locked doors, roof access or ceiling voids
- Name a contact who can let us in at the agreed time
Ask for a quote
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

Signs you need AHU cleaning in Welborne
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
It’s time to book a visit if you see:
- Units that have only ever had filter changes
- Dirty coils holding back the airflow
- Air handling units with blocked filters
- Plant that needs cleaning after a refit
Healthcare ventilation, from large hospitals like Knowle Hospital (about 0.5 miles west) to small clinics, depends on clean filters, coils and ducts.
What to look for in a quote
- What records you’ll receive afterwards
- Whether the whole system is included, or only the parts that are easy to reach
- How areas they cannot reach will be recorded
- How VAT is shown on the quote
For landlords and multi-site operators
From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
Common questions in Welborne
Is Welborne within the area you cover?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Do you do school ventilation cleaning in Welborne in the summer holidays?
Yes, holiday work suits schools best. Around Welborne, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. You can call 0345 646 2711 or use the quote form with the dates the site is empty.
What should I send you?
Some pictures and a quick description of the system plus the address and your hours. If we need more, we will ask.
Do you offer emergency callouts?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we’ll talk you through the next steps.
Will the ventilation be off while you clean?
Yes, while the clean is under way. Out-of-hours work is available so the building is not left without ventilation when it’s busy.
Do you work with multi-site operators?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
Do you clean the ductwork as well?
Yes, supply and extract ducts, grilles and diffusers. We will tell you after the survey whether the ducts need it.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What a clean won’t put right
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning won’t do:
- Airflow problems caused by the system’s design
- The supply and extract ducts, quoted separately
- Coils that are corroded or leaking and need replacing
If you’re not sure, just call us on 0345 646 2711, or email photos and we will give you a straight answer before you book.
Where we work
- Drain trays
- Dampers and louvres
- Supply and extract fans
- Heating and cooling coils
- Filter sections
- Internal panels
What happens if it’s left?
Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. In a place like Welborne, ductwork and fans are easy to forget until something goes wrong.
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and why the quote is fixed before any work starts.
Why Welborne businesses choose us

What affects the cost of AHU cleaning
The price is fixed before any work begins. It takes into account:
- How easy every part is to reach
- One-off work versus a regular cycle
- Working hours and out-of-hours timing
- Where the site is and how we reach it
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before we start.
Asking for a quote
Before you ask for a quote, gather:
- How we’d reach plant on a roof or in a plant room
- Photos showing the whole system and its surroundings
- The paperwork from the last visit, if you have it
- Where the site is and what kind of site it is
