AHU Cleaning in Harvel
For cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces in Harvel, one call is all it takes: survey, fixed quote, work and sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Odours coming through the supply air

For landlords and multi-site operators
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
We also work for facilities teams across offices, schools and healthcare across Kent. Work can be phased by floor, building or site to keep disruption down.
How we handle AHU cleaning in Harvel
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. If you’re dealing with drain trays holding standing water and debris and leaves in the fresh air intake, we can put it right, from dampers and louvres, internal panels and heating and cooling coils onwards.
For a building in or near Harvel, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Why it’s worth doing now in Harvel
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, ready to show anyone who asks. Systems in rural buildings are often out of sight and out of mind.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote, and the price is fixed before any work starts.

Questions from Harvel
Can you come to Harvel after we close?
Yes, nights and weekends are routine for us. It means the site in Harvel keeps running as normal. When you call us on 0345 646 2711 or drop us a line, mention when the site is quiet.
Can ventilation in schools around Harvel be cleaned out of term?
Yes, holiday work suits schools best. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Harvel, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Do you do ventilation duct cleaning too?
Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can survey both on the same visit.
How do you protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
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.
What if parts of the system can’t be reached?
Anything we can’t reach goes on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.
How much notice do you need?
Earlier is better, particularly for night and weekend visits. We typically quote within one working day, and there’s a 24/7 line for emergencies.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
The process
Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere as small as Harvel, the date and timings are agreed with you well before the day.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Getting ready for the visit
- Mention any parking or loading restrictions
- Make sure equipment near the work can be switched off and left to cool
- Let us know when the site is closed or quiet

Looking after it afterwards
To keep the system working properly between visits:
- Keep the certificate and photo report with the plant records
- Book the next check in line with the report
- Make sure condensate is draining away
- Watch for drips or damp patches near the plant
Stick to the filter change schedule, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.

What the work involves, part by part
Fans and fan sections
Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
Do you need AHU cleaning in Harvel?
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. Months can pass without anyone looking inside.
Clients usually contact us after spotting one of these:
- Air handling units due a clean after building work
- Odours coming through the supply air
- Dust built up on fan impellers
- Condensate trays that will not empty
Ventilation work in and around Harvel is risk-based: inspect, then clean what needs it.
