AHU cleaning in Sandwich
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. Common call-outs are for plant that has been serviced but not cleaned and debris and leaves in the fresh air intake, across filter sections, supply and extract fans and internal panels.
Visits to a place like Sandwich are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What AHU cleaning looks like in Sandwich
There are about 3 caring premises (care homes, nurseries and hospitals) on the FSA’s food hygiene register within about 1.5 miles of central Sandwich. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. The nearest hospital to Sandwich is Ramsgate General Hospital, about 5 miles north-east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
If you run an office near Sandwich station, its supply ductwork can gather dust for years before anyone looks inside. Ramsgate General Hospital, about 5 miles north-east, is the nearest hospital to Sandwich, and healthcare sites of every size need their supply air kept clean.

Aftercare tips
A little care between visits keeps the system in better shape. Our advice:
- Look at the condensate drain whenever the unit is serviced
- Change filters on schedule and log each change
- Report water on the plant room floor
- Keep the area around the fresh air intake clear
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
Sandwich questions
Can the work in Sandwich be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. That way a site in Sandwich doesn’t have to lose a day’s trading. When you give us a ring on 0345 646 2711 or send us an email, mention when the site is quiet.
Can you get to a site in Sandwich?
Yes. Villages and rural sites across the South East are part of our work, Sandwich included. Just mention lanes, gates or anything else about the site when you book.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
What do you clean inside the unit?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before any work starts, and anything we remove is contained. At the end, the area is cleaned down.
Are you fully insured?
Yes. We’re fully insured, and the details are available on request.
When should our AHU next 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.
Do you look at the system first?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.

What else we do in Sandwich
Honest limits
AHU cleaning cannot fix everything, and we will tell you before we start. It does not solve:
- Dirty ducts beyond the unit itself
- Problems with the unit’s controls or sensors
- Leaking heating or cooling coils
If in doubt, call 0345 646 2711 or send us an email and we’ll say what we think.
Parts of the system we cover
- Filter sections
- Heating and cooling coils
- Dampers and louvres
- Supply and extract fans
- Drain trays
- Internal panels
The process
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. On site, it takes one overnight shift for many single units, with bigger plant phased. Your opening hours decide when we come to Sandwich, not ours.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Getting ready for the visit
- Tell us where we can park and unload
- 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

What staff can safely do
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. Reaching it takes a specialist with the right equipment.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Part by part
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Signs you need AHU cleaning in Sandwich
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and slime and smells soon follow.
It’s time to book a visit if you see:
- Units that have only ever had filter changes
- Drain trays holding standing water
- Units needing a clean before a new tenant or handover
- Dust built up on fan impellers
For schools like Sandwich Infant School, the holidays are the usual time to inspect and clean ventilation.
