About our AHU cleaning in Teston
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. The work covers supply and extract fans, heating and cooling coils and dampers and louvres, and the jobs we see most are units that have only ever had filter changes and dirty filters cutting the airflow.
Work in a small place like Teston starts with agreeing access and timings.
The report is your system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

How we price AHU cleaning
You will get a fixed price before any work starts. It takes into account:
- The scale of the work
- When the work can happen, such as evenings, overnight or weekends
- One-off work versus a regular cycle
- The condition we find in the survey
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, ring 0345 646 2711, or send details by email and we’ll give you an honest view and a fixed quote.
Helping us quote
There’s no need for technical detail. Just send:
- How we’d reach plant on a roof or in a plant room
- The times we could work without disrupting the site
- Close-ups of filters, grilles, hatches or access panels
- Problems your staff have spotted
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

What else we do in Teston
What your team can do, and what needs us
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
Teston buildings and their air
Going by the FSA’s register, there are about 3 schools, colleges and universities and about 3 hospitals, care homes and childcare premises serving food in and around Teston, up to about a mile and a half out. Busy, occupied buildings like these are where clean supply air matters most. At about 29 miles from central London, Teston sits well inside the area we cover. We work evenings, overnight and at weekends, so the visit fits around the site. Oakwood Hospital is the nearest hospital, about 2.1 miles north-east of Teston.

Oakwood Hospital, about 2.1 miles north-east, is the nearest hospital to Teston, and healthcare sites of every size need their supply air kept clean. School buildings such as Wateringbury Church of England Primary School are typically done in the holidays, so classrooms aren’t disturbed.

How it works
There’s very little for your team to do 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. A quick note on how to find the site and where to park makes a visit to Teston run smoothly.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Agree a time when the area can be out of use
- Name a contact who can let us in at the agreed time
- Mention any sign-in, permit or induction we need
How to get a quote

Common problems we fix in Teston
Whatever surrounds a building in Teston, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
Signs it’s time to call us include:
- Plant that needs cleaning after a refit
- Dirty coils holding back the airflow
- Filters that are clogged or overdue
- Plant that has been serviced but not cleaned
If you manage offices or shops near Wateringbury station, their ventilation can be inspected and cleaned out of hours.

Aftercare tips
Simple habits between visits make a real difference. We recommend:
- Note any water around the unit or leaks below it
- Plan the next inspection before the last report gets filed away
- Keep filter changes on time and recorded
- Keep inspection doors on the unit in good order
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
How the job changes from site to site
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey, before we quote.
