Where buildings like these have air handling units, filters, coils and drain trays need regular attention. For Farncombe, the closest hospital is Milford Hospital, roughly 2.2 miles south.

Hospitals such as Milford Hospital (about 2.2 miles south) show how much a building can rely on clean ventilation, and smaller healthcare sites near Farncombe are no different.

AHU cleaning in Farncombe
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. Common call-outs are for units that have only ever had filter changes and rooms that smell stuffy when the system runs, on heating and cooling coils, drain trays and filter sections.
Visits to a place like Farncombe are fitted around opening hours. The method does not change: inspect first, clean, then record what was done.
Good records are part of the job. You get a written report with pictures after every visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What affects the cost of AHU cleaning
Every site gets its own quote. These are the things that affect it:
- The number of sites or systems
- Any permits to work or inductions
- Travel, parking and unloading
- Working hours and out-of-hours timing
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.
What to send for a quote
To speed up the quote, please include:
- The site address and the type of premises
- Any access panels or hatches you can see
- Any symptoms, from odd noises to smells or leaks
- Any previous report or certificate
There’s no standard price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then send you a fixed quote. To start, call 0345 646 2711 or use the quote form.
For landlords and multi-site operators
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
What we do, step by step
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. In a place like Farncombe, we fit the visit around your hours.
- 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.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Allow time for equipment near the work to be turned off and cool down
- Mention any parking or loading restrictions
- Tell us the best time to work, such as after service or at a weekend

Farncombe: your questions answered
Do you work in villages like Farncombe?
Yes, we work in villages as well as towns, and Farncombe is covered. Let us know about access, parking and anything unusual about getting there when you book.
Do you work at weekends in Farncombe?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. When you ring 0345 646 2711 or send us an email, mention when the site is quiet.
How much notice do you need?
Earlier is better, particularly for night and weekend visits. Quotes typically come back within one working day, and emergencies are covered by our 24/7 line.
Which accreditations do you hold?
We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What should I send you?
A short description and a few photos plus the address and your hours. We’ll ask for anything else we need.
Do you look at the system first?
Yes. We always survey first, either from pictures and details you send or on a site visit. A fixed quote follows.
Is a quote from photos possible?
Normally, yes. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote usually follows within one working day. Some sites still need a visit, and we’ll say so.
Do you clean the ductwork as well?
Yes, supply and extract ducts, grilles and diffusers. We will tell you after the survey whether the ducts need it.
Between visits
Looking after the system between visits is straightforward, and it helps at the next visit:
- Report stiff or damaged access doors
- Keep filter changes on time and recorded
- Check the drain tray is emptying during routine visits
- Plan the next inspection before the last report gets filed away
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to confirm water is draining away.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
Why deal with it now?
Dirt left in an air handling unit doesn’t stay in the unit. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. Light use slows the build-up but doesn’t stop it.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.

What we’re called out for in Farncombe
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, a little more each month.
If you notice any of these, it’s worth a diagnosis:
- Blocked condensate drains and slimy trays
- Air handling units never cleaned inside
- Air handling units with blocked filters
- Odours coming through the supply air
If you manage a school such as Farncombe Church of England Infant School, ventilation cleaning is best booked for the holidays.
Questions to ask before you book
- Whether the quote shows VAT
- When they can work, and whether that’s outside your opening hours
- Whether they recommend a next date
