AHU cleaning for kitchens and businesses in Weston Green
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 you can see the unit’s condition for yourself. Common call-outs are for dust-coated heating and cooling coils and dirty filters cutting the airflow, on heating and cooling coils, filter sections and dampers and louvres.
Somewhere as small as Weston Green, ducted ventilation is usually 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.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How it works
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Rural roads and tight entrances are worth telling us about before a visit to Weston Green.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Let us know when the site is closed or quiet
- Name a contact who can let us in at the agreed time
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
Photos are the quickest way to a quote: 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 many jobs can be priced from that alone.
Advice
Weston Green buildings and their air
Food Standards Agency data includes about 11 schools, colleges and universities and about 21 care, childcare and hospital premises in and around Weston Green, up to about a mile and a half out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. The nearest hospital to Weston Green is Tolworth Hospital, about 2.4 miles east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. About 13 miles out from central London, Weston Green is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site.
If you run an office near Thames Ditton station, its supply ductwork can gather dust for years before anyone looks inside. Wherever a school like Esher College has ducted ventilation, a half-term visit keeps the work out of lesson time.
Weston Green is about 2 miles west of Surbiton, in Surrey. We carry out AHU cleaning for businesses, landlords and public buildings in Weston Green and the rest of Surrey.

Do you need AHU cleaning in Weston Green?
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
Signs it’s time to call us include:
- Air handling units due a clean after building work
- Fan sections that haven’t been cleaned in years
- Dirty filters cutting the airflow
- Rooms that smell stuffy when the system runs
If you run a surgery, dental practice or care home near Weston Green, clean ventilation matters as much to you as to a hospital like Tolworth Hospital (about 2.4 miles east).
Questions to ask before you book
- Proof of insurance
- Whether a written report and photos are included
- How they set the interval to the next visit
- Whether the whole system is included, or only the parts that are easy to reach
Part by part
Internal casing and panels
We open each section through its doors and close them securely when we’re done before the unit is handed back.
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
Landlords, agents and facilities managers
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
Between visits
Looking after the system between visits is straightforward, and it helps at the next visit:
- Look at the condensate drain whenever the unit is serviced
- Keep the certificate and photo report with the plant records
- Watch for drips or damp patches near the plant
- Keep inspection doors on the unit in good order
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
Leave it or put it right?
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. It’s simpler to plan the work at Weston Green now than to arrange it in a hurry later.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, call 0345 646 2711, or send details by email for straight advice and a fixed quote.

Yes. Villages and rural sites across the South East are part of our work, Weston Green included. Photos of the system and directions to the site help us plan the visit.
Do you clean school ventilation in Weston Green in the holidays?
Yes, out-of-term visits are normal for schools. There are about 11 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Weston Green. Booking early in the term gives the best choice of holiday dates.

What 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. We fix the price before any work starts.
How do you keep the site clean during the work?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
What do you need from me for a quote?
A short description and a few pictures, with the address and opening hours. If we need more, we will ask.

Do you give a certificate after the clean?
Yes, both a certificate and a report with pictures. It includes a recommended date for the next check.
