AHU Cleaning in Gunville
Our technicians work in Gunville on AHU cleaning. Out-of-hours visits, a fixed quote and a written report with pictures as standard.
- Air handling units with blocked filters
- Odours coming through the supply air
- Condensate trays that will not empty
What happens on the day
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before we start, and floors and nearby surfaces are sheeted. The work itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere like Gunville, lanes, gates and parking are worth mentioning in advance.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Have your last certificate or report to hand
- Agree a time when the area can be out of use
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before work begins.

AHU cleaning in Gunville
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with pictures, so the report shows exactly what was done. Common call-outs are for filters that are clogged or overdue and coils clogged with dust and debris, on dampers and louvres, drain trays and filter sections.
Somewhere as small as Gunville, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, 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.

How we price AHU cleaning
The quote reflects the site in front of us. We consider:
- The condition we find in the survey
- How easy every part is to reach
- How big the system is
- The number of sites or systems
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. You will have a fixed price before work begins.
Asking for a quote
To speed up the quote, please include:
- Where the site is and what kind of site it is
- The paperwork from the last visit, if you have it
- Detail shots of panels, filters and grilles
- The roof, plant room or outside wall the system runs to

When it’s something else
In fairness, some problems need a different fix:
- Coils that are corroded or leaking and need replacing
- Problems with the unit’s controls or sensors
- Ventilation that was badly designed in the first place
If you’re not sure, just phone us on 0345 646 2711 or use the quote form and we’ll give you a straight answer before you book.

Gunville: your questions answered
Can ventilation in schools around Gunville be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. With about 13 schools and colleges on the FSA’s register within roughly a mile and a half of Gunville, it pays to plan holiday dates ahead. Send us your term dates when you call 0345 646 2711 or send us an email, and we’ll fit the work in.
Do you cover smaller places like Gunville?
Yes. Gunville is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you give a certificate after the clean?
Yes, both a certificate and a report with photos. It includes a recommended date for the next check.
How much does AHU cleaning cost?
We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before any work starts.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
Do you offer maintenance contracts?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
What we’re called out for in Gunville
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
If you notice any of these, it’s worth a diagnosis:
- Dirty fans and fan housings
- Dust-coated heating and cooling coils
- Debris and leaves in the fresh air intake
- Air handling units never cleaned inside
Healthcare ventilation, from large hospitals like St Mary's Hospital (about 1.2 miles north-east) to small clinics, depends on clean filters, coils and ducts.
Questions to ask before you book
- Whether inaccessible sections are listed on the report
- Whether the quote is based on a survey or photos
- What hours they’ll be on site
- Whether VAT is included
Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Different parts, different methods
Drain trays
Older trays can corrode and start leaking. We record their condition with pictures so repairs can be planned.
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
Gunville buildings and their air
Food Standards Agency data includes about 13 schools, colleges and universities, about 6 care, childcare and hospital premises and about 6 hotels, B&Bs and guest houses within about 1.5 miles of central Gunville. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. For Gunville, the closest hospital is St Mary's Hospital, roughly 1.2 miles north-east. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
School buildings such as Carisbrooke College are usually done in the holidays, so classrooms are not disturbed.

Near you in Gunville

Why deal with it now?
If people in a building in Gunville complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. Equipment tucked in a roof space or outbuilding near Gunville rarely gets looked at unless someone books it.
What you pay reflects the actual work. That’s why every job is surveyed first, and why the quote is fixed before work begins.
