Ventilation in Dunk's Green buildings
Going by the FSA’s register, there are about 3 schools, colleges and universities serving food within about 1.5 miles of central Dunk's Green. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. About 5.3 miles south of Dunk's Green is Tonbridge Cottage Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. Dunk's Green is about 24 miles from central London, well within the area we cover across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you.
Classrooms and halls at schools such as Plaxtol Primary School are easiest to work in when pupils are away.

AHU cleaning in Dunk's Green, done properly
If the units serving a building in Dunk's Green have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. The work covers heating and cooling coils, filter sections and drain trays, and the jobs we see most are drain trays holding standing water and air handling units with blocked filters.
For a building in or near Dunk's Green, access is agreed in advance and the visit is planned around the journey.

Common questions in Dunk's Green
Can you clean school ventilation in Dunk's Green during the holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 3 schools and colleges with food registrations within roughly a mile and a half of Dunk's Green. Just call us on 0345 646 2711 or use the quote form with your term dates and we will plan around them.
Do you work overnight in Dunk's Green?
Yes, evening, overnight and weekend work is normal for us. That way a site in Dunk's Green does not have to lose a day’s trading. Your opening times are the first thing we ask for.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
Can you fix a faulty AHU?
Our AHU work is cleaning rather than mechanical repair. Any faults we notice are recorded so your maintenance contractor can deal with it.
How far ahead should we book?
The more notice, the better, particularly for night and weekend visits. We usually quote within one working day, and emergencies are covered by our 24/7 line.
Will the ventilation be off while you clean?
Yes, for the time we’re working on it. We can work evenings, overnight or at weekends to keep disruption down.
Is a quote from pictures possible?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we typically come back within one working day. Some sites still need a visit, and we’ll say so.
Do you work in Dunk's Green?
Yes. Our technicians work in Dunk's Green, as part of our area across London and the South East.
How we price AHU cleaning
Your quote is based on your site. We consider:
- Whether several sites go on one quote
- How easy every part is to reach
- One-off work versus a regular cycle
- What state the system is in
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and the price is agreed before we start.
What to send for a quote
Photos let us diagnose from a distance. Try to include:
- The paperwork from the last visit, if you have it
- Close-ups of filters, grilles, hatches or access panels
- Wide pictures of the system and the area around it
- The postcode and the type of business
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.
When to call us in Dunk's Green
Air handling units are usually tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
What we’re most often called out for:
- Fan sections that haven’t been cleaned in years
- Dust-coated heating and cooling coils
- Leaves and litter drawn into the unit
- Units needing a clean before a new tenant or handover
Tonbridge Cottage Hospital, about 5.3 miles south, is the nearest hospital to Dunk's Green, and healthcare sites of every size need their supply air kept clean.

Why deal with it now?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that does not feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. Rural sites cannot always move to another kitchen or room when something fails.
You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.

Keeping the system healthy
So the system stays in good health:
- Look at the condensate drain whenever the unit is serviced
- Make sure the unit’s access doors open easily
- Clear leaves and litter away from the intake
- Keep the certificate and photo report with the plant records
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. A drain that is cleared early never gets to the slime stage.
What staff can safely do
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
How the visit works
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes anything from half a day for one small unit to several shifts for a plant room full of them, and we clear up before we go. If you can send photos, we can arrive in Dunk's Green knowing what to expect.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Make sure someone can let us in and lock up afterwards
- Tell us the best time to work, such as after service or at a weekend
Ask for a quote
Quotes are quick. Call or email with a few details and you will typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Advice
Part by part
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. We clean the impeller, housing and surrounding section.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
