About our AHU cleaning in Warnborough Green
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from photos or on site, followed by a fixed quote, so you know where you stand. The work covers drain trays, supply and extract fans and dampers and louvres, and the jobs we see most are dirty filters cutting the airflow and drain trays holding standing water.
For a building in or near Warnborough Green, access is agreed in advance and the visit is planned around the journey.
Think of the report as the system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

FAQs for Warnborough Green
Do you cover smaller places like Warnborough Green?
Yes, Warnborough Green is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
Can you clean school ventilation in Warnborough Green during the holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 6 schools and colleges with food registrations within roughly a mile and a half of Warnborough Green. Tell us your holiday dates and we will book the visit for when the site is empty.
Do you look at the system first?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. Then you get a fixed quote.
Can one contract cover all our sites?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
Will you repair the fan or motor?
Our AHU work is cleaning rather than mechanical repair. Any faults we notice are recorded so your maintenance contractor can deal with it.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We don’t leave it behind.
Do you have insurance?
Yes. We carry full insurance and have been trading since 2009.
How much notice do you need?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
Part by part
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.
What we do, step by step
Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. If the van will struggle with a lane or gateway near Warnborough Green, let us know and we’ll plan around it.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Before we arrive
- Clear loose items from the work area

Advice
Why it’s worth doing now in Warnborough Green
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 Warnborough Green now than to arrange it in a hurry later.
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before work begins, so there are no surprises.

What a clean won’t put right
AHU cleaning can’t fix everything, and we will tell you before work begins. It does not solve:
- Faulty motors, drives or bearings
- Controls and BMS settings that run the unit
- Ventilation that was badly designed in the first place
If in doubt, give us a ring on 0345 646 2711 or drop us a line and we will say what we think.
Parts of the system we cover
- Heating and cooling coils

What affects the cost of AHU cleaning
The survey tells us what the work involves. We look at:
- Any permits to work or inductions
- Whether it’s a one-off visit or part of a schedule
- The condition we find in the survey
- How easy every part is to reach
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before any work starts.
What we need to know
Many jobs can be priced from photos and some basics. Send what you can of the following:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- How we’d reach plant on a roof or in a plant room
- Detail shots of panels, filters and grilles
- The times we could work without disrupting the site
There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To get going, call 0345 646 2711, or email photos.

Signs you need AHU cleaning in Warnborough Green
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Warnborough Green, that’s air they breathe for hours at a time.
The symptoms we are asked about most are:
- Intake sections clogged with outdoor debris
- Units that have only ever had filter changes
- Stale or musty smells from the ventilation
- Dirty fans and fan housings
Hospitals such as Fleet Community Hospital (about 5.1 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Warnborough Green are no different.
What to look for in a quote
- When they can work, and whether that’s outside your opening hours
- Exactly which parts of the system are covered
- Whether VAT is included
- When the next visit should be, and why
Looking after it afterwards
Aftercare is simple, and it helps at the next visit:
- Watch for drips or damp patches near the plant
- Keep inspection doors on the unit in good order
- Report musty smells from the vents straight away
- Book the next check in line with the report
The report suggests a date for the next inspection or clean, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
