How we handle AHU cleaning in Wanshurst Green
We clean air handling units for buildings in Wanshurst Green and across Kent, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. We’re often asked to deal with filters that are clogged or overdue and odours coming through the supply air, on supply and extract fans, filter sections and dampers and louvres.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
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.

- A system that is undersized for the building
- Dirty ducts beyond the unit itself
If in doubt, ring 0345 646 2711 or use the quote form and we will say what we think.

How the visit works
A visit follows the same order every time: protect the area, isolate whatever needs isolating, carry out the AHU cleaning, tidy up and hand over the paperwork. On site, the work takes from a few hours for a compact unit to a day or more for a large one. Visits to a village like Wanshurst Green are booked in advance, at a time that suits whoever runs the site.
- We survey the unit from pictures or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Allow time for equipment near the work to be turned off and cool down
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Clear loose items from the work area

Related advice
What we are called out for in Wanshurst Green
Filters that are not changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
If you notice any of these, it’s worth a diagnosis:
- Condensate trays that won’t empty
- Air handling units never cleaned inside
- Debris and leaves in the fresh air intake
- Rooms that smell stuffy when the system runs
Every job around Wanshurst Green ends with a record of what was cleaned and what was found.
Questions to ask before booking
- Whether the price is fixed
- What’s included in the scope, part by part
- Whether they recommend a next date
- Whether inaccessible sections are listed on the report
What the work involves, part by part
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
Internal casing and panels
We open each section through its doors and close them securely when we’re done before the unit is handed back.

What affects the quote in Wanshurst Green
The price is fixed before any work begins. It’s based on:
- The condition we find in the survey
- Whether we need access equipment or extra panels
- One-off work versus a regular cycle
- Travel, parking and unloading
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before we start.
Helping us quote
You do not need the technical terms. Just send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The times we could work without disrupting the site
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The paperwork from the last visit, if you have 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, the quote is fixed before any work is booked.
Why deal with it now?
If people in a building in Wanshurst Green complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. In a small place like Wanshurst Green, a system that fails can take a site out of use.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before we start.

Wanshurst Green questions
Do you clean school ventilation in Wanshurst Green in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 3 schools, colleges and universities with registered kitchens within about a mile and a half of Wanshurst Green. Send us your term dates when you phone us on 0345 646 2711 or email us, and we will fit the work in.
Do you work overnight in Wanshurst Green?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Wanshurst Green needn’t be disturbed. Just phone us on 0345 646 2711, or send details by email with your opening times and we will plan around them.
How do you protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Can you clean the ducts connected to the AHU?
Yes, the ductwork, grilles and diffusers the unit serves. We will tell you after the survey whether the ducts need it.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
Do you look at the system first?
Yes. We always survey first, either from pictures and details you send or on a site visit. A fixed quote follows.
Which parts of an air handling unit do you clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
In-house cleaning or a specialist?
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.
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 they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
