AHU cleaning for kitchens and businesses in Sandhurst
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. The work covers supply and extract fans, internal panels and filter sections, and the jobs we see most are dust built up on fan impellers and stale or musty smells from the ventilation.
In a village or hamlet like Sandhurst, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Every visit ends with a written report and photos, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Sandhurst questions
Can you work in Sandhurst outside opening hours?
Yes, evening, overnight and weekend work is normal for us. The work in Sandhurst can fit around your hours. Tell us your opening hours when you ask for a quote.
Do you work in villages like Sandhurst?
Yes. Villages and rural sites across the South East are part of our work, Sandhurst included. Just mention lanes, gates or anything else about the site when you book.
What about areas you can’t get to?
Anything we cannot reach goes on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
Is a quote from photos possible?
Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.
How long does it take to clean an air handling unit?
As a guide, it takes from a few hours for a compact unit to a day or more for a large one. We plan the shutdown around that, including evenings or weekends.
What do you clean inside the unit?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
Can you come out in an emergency?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
What should I send you?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. After that, simply ring 0345 646 2711 or email us.
What we do, step by step
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before work begins, and floors and nearby surfaces are sheeted. The work itself takes anything from half a day for one small unit to several shifts for a plant room full of them. A quick note on how to find the site and where to park makes a visit to Sandhurst run smoothly.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Before we arrive
- Tell us about site rules, permits or sign-in
- Allow time for equipment near the work to be turned off and cool down
- Let us know about parking and loading

What AHU cleaning looks like in Sandhurst
The FSA’s food hygiene register lists about 4 schools, colleges and universities with registered kitchens or food service within 1.5 miles or so of the middle of Sandhurst. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. The nearest hospital to Sandhurst is Benenden Hospital, about 4.8 miles north-east. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. At about 43 miles from central London, Sandhurst sits well inside the area we cover. Evening, overnight and weekend visits are all possible.
If you run a surgery, dental practice or care home near Sandhurst, clean ventilation matters as much to you as to a hospital like Benenden Hospital (about 4.8 miles north-east). If you manage a school such as Sandhurst Primary School, ventilation cleaning is best booked for the holidays.

Fixed quotes for AHU cleaning in Sandhurst
Every site gets its own quote. This is what makes a difference:
- One-off work versus a regular cycle
- Parking and loading at the site
- The condition we find in the survey
- Whether several sites go on one quote
What you pay depends on the size of the system, the condition it’s in and access to every part of it. We give you a fixed price before work begins, so you know where you stand.
Helping us quote
There’s no need for technical detail. Just send:
- Any previous report or certificate
- Close-ups of filters, grilles, hatches or access panels
- Any symptoms, from odd noises to smells or leaks
- Wide photos of the system and the area around it
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.
How the job changes from site to site
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
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 a clean will not put right
To be straight with you, there are a few things this work won’t fix:
- Damaged coils beyond cleaning
- Airflow problems caused by the system’s design
- Building management system faults
Not sure which it is? You can call us on 0345 646 2711, or email photos and we will tell you honestly.
Parts of the system we cover
- Dampers and louvres
- Supply and extract fans
- Filter sections
- Internal panels
- Drain trays
- Heating and cooling coils
What your team can do, and what needs us
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Change filters on schedule and log each change
- Look at the condensate drain whenever the unit is serviced
- Plan the next inspection before the last report gets filed away
- Keep the area around the fresh air intake clear
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
Why deal with it now?
Dirt left in an air handling unit does not 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. With notice, the visit to Sandhurst can be fitted around your bookings and events.
