AHU cleaning in Freefolk, done properly
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 are not flattened. If you’re dealing with fan sections that haven’t been cleaned in years and air handling units due a clean after building work, we can help.
Work in a small place like Freefolk starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
What AHU cleaning looks like in Freefolk
Going by the FSA’s register, there are about 3 schools, colleges and universities and about 4 hospitals, care homes and childcare premises serving food within roughly a mile and a half of the centre of Freefolk. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Freefolk is about 55 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.
Wherever a school like Testbourne Community School has ducted ventilation, a half-term visit keeps the work out of lesson time.

FAQs for Freefolk
Do you clean school ventilation in Freefolk in the holidays?
Yes, and it’s the easiest time to do it. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Freefolk, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Is Freefolk within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Freefolk included. Just mention lanes, gates or anything else about the site when you book.
What’s included in an AHU clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. We confirm the scope after looking at the unit.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Do you work evenings or weekends?
Yes. We time the work to fit the building’s hours. In hospitals and care homes, we agree timings with the site team.
Do you need to switch the unit off?
Yes, while the clean is under way. We can work evenings, overnight or at weekends to keep disruption down.
Different parts, different methods
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.
When to call us in Freefolk
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, a little more each month.
It’s time to book a visit if you see:
- Debris and leaves in the fresh air intake
- Dirty fans and fan housings
- Filters that are clogged or overdue
- Units needing a clean before a new tenant or handover
In Freefolk, we look inside the system before deciding what needs cleaning.
Questions to ask before booking
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether the figure could change on the day
- Proof of insurance
- Whether a survey comes first
Aftercare tips
So the system stays in good health:
- Keep inspection doors on the unit in good order
- Look at the condensate drain whenever the unit is serviced
- Report water on the plant room floor
- Report musty smells from the vents straight away
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
What we do, step by step
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, and that takes half a day to a full day per unit, with large plant planned over several shifts. If the van will struggle with a lane or gateway near Freefolk, let us know and we’ll plan around it.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Clear loose items from the work area
- Tell us the best time to work, such as after service or at a weekend
- Let us know how we reach the system, including roofs, risers and plant rooms

Related advice
What happens if it’s left?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, ready to show anyone who asks. In a place like Freefolk, ductwork and fans are easy to forget until something goes wrong.
The cost depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before work begins, so you know where you stand.
