AHU cleaning in Herne
Heating and cooling coils trap dust that gets past the filters. 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, filter sections and dampers and louvres, and the jobs we see most are rooms that smell stuffy when the system runs and filters that are clogged or overdue.
Smaller buildings around Herne often keep their ventilation units in a roof void or plant cupboard, where they’re easy to forget. Filters, coils and drain trays need attention whatever the size of the unit.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Part by part
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
Common problems we fix in Herne
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. So a unit can be well maintained and still dirty.
It’s time to book a visit if you see:
- Intake sections clogged with outdoor debris
- Drain trays holding standing water
- Dust-coated heating and cooling coils
- Rooms that smell stuffy when the system runs
Wherever a school like Herne Church of England Infant School has ducted ventilation, a half-term visit keeps the work out of lesson time.

- When the next visit should be, and why
- What paperwork you get at the end
- If they look at the system before pricing
What affects the quote in Herne
Every site gets its own quote. This is what makes a difference:
- How many systems or sites are involved
- One-off work versus a regular cycle
- What state the system is in
- When the work can happen, such as evenings, overnight or weekends
The cost depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before we start, so there are no surprises.
Helping us quote
To help us quote quickly, please include:
- The postcode and the type of business
- Close-ups of filters, grilles, hatches or access panels
- Problems your staff have spotted
- Your opening hours and when the area is out of use
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

- Controls and BMS settings that run the unit
If you are not sure, just call 0345 646 2711, or email photos and we’ll give you a straight answer.

How the visit works
Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. In a smaller place like Herne, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Preparing for the visit
- Clear loose items from the work area
- Let us know about parking and loading
- Allow time for equipment near the work to be turned off and cool down

What happens if it’s left?
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. Booking now means the visit to Herne is planned around you, not forced by a breakdown.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will go through it with you.

Aftercare tips
Simple habits between visits make a real difference. Our advice:
- Make sure condensate is draining away
- Do not store bins or materials near the intake
- Report stiff or damaged access doors
- Don’t ignore odours coming through the grilles
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 make sure it stays clear.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
AHU cleaning in Herne: local notes
Food Standards Agency data includes about 7 schools, colleges and universities and about 27 care, childcare and hospital premises within roughly a mile and a half of the centre of Herne. Busy, occupied buildings like these are where clean supply air matters most. Herne is about 54 miles from central London, well within the area we cover across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site. Whitstable and Tankerton Hospital is the nearest hospital, about 3.7 miles west of Herne. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
Healthcare ventilation, from large hospitals like Whitstable and Tankerton Hospital (about 3.7 miles west) to small clinics, depends on clean filters, coils and ducts.
