What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
AHU cleaning in Farleigh Green, done properly
Our AHU cleaning covers sites in Farleigh Green and the rest of Kent, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. If you are dealing with fan sections that haven’t been cleaned in years and dirty coils holding back the airflow, we can put it right, from filter sections, heating and cooling coils and drain trays onwards.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Good records are part of the job. You get a written report with pictures after every visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Why it’s worth doing now in Farleigh Green
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. Rural sites cannot always move to another kitchen or room when something fails.
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and the price is agreed before work begins.

Fixed quotes for AHU cleaning in Farleigh Green
Before we fix a price, we need to know a few things. We check:
- Whether several sites go on one quote
- The times the site is available
- The condition of the system
- Parking and loading at the site
The cost depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before we start, so you know where you stand.
What we need to know
When you contact us, it’s useful to have:
- Close-ups of filters, grilles, hatches or access panels
- A few general shots of the system
- Problems your staff have spotted
- The times we could work without disrupting the site
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before any work starts.
Your questions about AHU cleaning in Farleigh Green
Can you come to Farleigh Green after we close?
Yes, evening, overnight and weekend work is normal for us. The work in Farleigh Green can fit around your hours. Your opening times are the first thing we ask for.
Do you clean school ventilation in Farleigh Green in the holidays?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 4 schools, colleges and universities with registered kitchens within about a mile and a half of Farleigh Green. Just give us a ring on 0345 646 2711 or use the quote form with your term dates and we will plan around them.
What’s 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 it takes a risk-based approach.
Do you repair air handling units?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
How much does AHU cleaning cost in Farleigh Green?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before we start.
Where does the waste go?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
Is there a report after cleaning?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Do you need AHU cleaning in Farleigh Green?
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
It’s time to book a visit if you see:
- Dirty coils holding back the airflow
- Dirty filters cutting the airflow
- Air handling units due a clean after building work
- Stale or musty smells from the ventilation
Wherever a school like East Farleigh Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
What your quote should include
- How areas they cannot reach will be recorded
- Whether the quote is based on a survey or pictures

- What records you’ll receive afterwards
What happens on the day
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes from a few hours for a compact unit to a day or more for a large one. Rural roads and tight entrances are worth telling us about before a visit to Farleigh Green.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
