How the visit works
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. If the van will struggle with a lane or gateway near Greywell, let us know and we will plan around it.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Find the previous report, if there is one
- Clear the space around the work
- Tell us about site rules, permits or sign-in

AHU cleaning in Greywell, done properly
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. The work covers drain trays, dampers and louvres and internal panels, and the jobs we see most are dust built up on fan impellers and filters that are clogged or overdue.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Good records are part of the job. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

AHU cleaning in Greywell: local notes
The FSA’s food hygiene register lists about 3 schools, colleges and universities and about 3 care, childcare and hospital premises with registered kitchens or food service within roughly a mile and a half of the centre of Greywell. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. We cover Greywell, about 41 miles from central London, as part of our work across London and the South East. Evening, overnight and weekend visits are all possible. About 5.6 miles east of Greywell is Fleet Community Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
Hospitals such as Fleet Community Hospital (about 5.6 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Greywell are no different. Wherever a school like Robert May's School has ducted ventilation, a half-term visit keeps the work out of lesson time.

- Problems with the unit’s controls or sensors
- Dirty ducts beyond the unit itself
- Faulty motors, drives or bearings

Why act early in Greywell
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. A fault that closes a site in a village like Greywell affects everyone who depends on it.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will explain each part.
Why book with us
- Every visit written up, with pictures
- A single point of contact for sites across the South East and London
- Fixed quotes from a survey or pictures
- Evenings, overnight and weekends, plus 24/7 emergency callout

Between visits
Looking after the system between visits is straightforward, and it helps at the next visit:
- Report water on the plant room floor
- Flag stale or damp smells in the supply air
- Plan the next inspection before the last report gets filed away
- Keep filter changes on time and recorded
Restart the unit with your site team or maintenance contractor once we’ve finished. Check the drain tray is emptying over the first few days to make sure it stays clear.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.
Part by part
Drain trays
A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.

Staff cleaning versus specialist work
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Fixed quotes for AHU cleaning in Greywell
The diagnosis comes before the price. The main factors are:
- What state the system is in
- One-off work versus a regular cycle
- Whether several sites go on one quote
- Travel, parking and unloading
What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before work begins.
Helping us quote
There’s no need for technical detail. It helps if you can send:
- Any symptoms, from odd noises to smells or leaks
- The site address and the type of premises
- A few general shots of the system
- Your last certificate, test record or report
Quotes are quick. Call or email with a few details and you’ll typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Greywell: your questions answered
Do you work at weekends in Greywell?
Yes. We work evenings, overnight and at weekends. It means the site in Greywell keeps running as normal. Tell us your opening hours when you ask for a quote.
Can a school’s ventilation in Greywell be done out of term time?
Yes, holiday work suits schools best. There are about 3 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Greywell. Booking early in the term gives the best choice of holiday dates.
How often should an air handling unit be cleaned?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and the report recommends a next date.
Can you quote from pictures?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Will the ventilation be off while you clean?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
How much notice should we give?
Book as early as you can for planned work, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.
