AHU cleaning in Willey Green
Where a building in Willey Green has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. If you are dealing with dirty filters cutting the airflow and drain trays holding standing water, we can help, from filter sections, supply and extract fans and drain trays onwards.
Somewhere as small as Willey Green, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
A written report with pictures follows each 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.

Multi-site and managed buildings
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
The process
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, do the work, clear away and leave you the report. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Rural roads and tight entrances are worth telling us about before a visit to Willey Green.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Allow time for equipment near the work to be turned off and cool down
- Mention any parking or loading restrictions
Ask for a quote
Quotes are quick. Call or email with a few details and you’ll usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

What AHU cleaning looks like in Willey Green
Going by the FSA’s register, there are about 4 schools, colleges and universities serving food within roughly a mile and a half of the centre of Willey Green. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. About 29 miles out from central London, Willey Green is part of the South East area we work across. The visit is fixed around your opening hours, not ours. The nearest hospital to Willey Green is Guildford Hospital, about 2.2 miles south-east. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
Wherever a school like Kings College Guildford has ducted ventilation, a half-term visit keeps the work out of lesson time.

Part by part
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
Honest limits
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning won’t do:
- Leaking heating or cooling coils
- Problems with the unit’s controls or sensors
- The supply and extract ducts, quoted separately
Not sure which it is? You can ring 0345 646 2711 or email us and we’ll tell you honestly.
Where we work
- Filter sections
- Drain trays
- Heating and cooling coils
- Supply and extract fans
- Internal panels
- Dampers and louvres
What affects the quote in Willey Green
We quote each job individually. These are the things that affect it:
- One-off work versus a regular cycle
- Site rules, permits and inductions
- The scale of the work
- The number of sites or systems
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before any work starts.
Asking for a quote
Before you ask for a quote, gather:
- Wide photos of the system and the area around it
- How we’d reach plant on a roof or in a plant room
- Any access panels or hatches you can see
- Any symptoms, from odd noises to smells or leaks
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.
When to call us in Willey Green
Filters that are not changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
Clients normally contact us after spotting one of these:
- Air handling units with blocked filters
- Fan sections that haven’t been cleaned in years
- Stale or musty smells from the ventilation
- Condensate trays that will not empty
If you run a surgery, dental practice or care home near Willey Green, clean ventilation matters as much to you as to a hospital like Guildford Hospital (about 2.2 miles south-east).

Willey Green: your questions answered
Can ventilation in schools around Willey Green be cleaned out of term?
Yes, holiday work suits schools best. Food Standards Agency records list about 4 schools, colleges and universities with registered kitchens within about a mile and a half of Willey Green. Tell us your holiday dates and we will book the visit for when the site is empty.
Can you come to Willey Green after we close?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Willey Green needn’t be disturbed. Just give us a ring on 0345 646 2711 or email us with your opening times and we will plan around them.
What is TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
How long will the unit be out of action?
The work takes a single shift for a typical unit, longer for large or heavily soiled ones. Bigger units can be phased, so call us on 0345 646 2711 or send us an email to talk it through.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
Are you accredited?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
What happens if you can’t reach some of it?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Keeping the system healthy
A little care between visits keeps the system in better shape. Our advice:
- Make sure the unit’s access doors open easily
- Flag stale or damp smells in the supply air
- Keep the certificate and photo report with the plant records
- Do not store bins or materials near the intake
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. They belong in the plant or maintenance log.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
