AHU cleaning in Forty Green
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. If you have stale or musty smells from the ventilation and dust-coated heating and cooling coils, we can put it right.
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.
We’ve been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

What staff can safely do
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
For landlords and multi-site operators
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.

What else we do in Forty Green
How it works
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. After that, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. A quick note on how to find the site and where to park makes a visit to Forty Green run smoothly.
- We look at the unit and the plant area during the survey.
- 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.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Mention any sign-in, permit or induction we need
- Clear loose items from the work area
- Make sure equipment near the work can be switched off and left to cool

What affects the quote in Forty Green
Every site gets its own quote. These are the things that affect it:
- The condition of the system
- Any permits to work or inductions
- Where the site is and how we reach it
- Whether we need access equipment or extra panels
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711 or email us, and we will talk you through it.
Asking for a quote
Photos let us diagnose from a distance. Try to include:
- The postcode and the type of business
- How we’d reach plant on a roof or in a plant room
- When the site is open and when it’s quiet
- Any access panels or hatches you can see
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Common questions in Forty Green
Do you work in villages like Forty Green?
Yes. Villages and rural sites across the South East are part of our work, Forty Green included. Photos of the system and directions to the site help us plan the visit.
Is AHU cleaning available in Forty Green?

How much notice do you need?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
What’s included in an AHU clean?
Every section that collects dirt: filters, coils, tray, fan and panels. We confirm the scope after looking at the unit.
Do you survey before quoting?
Yes. Photos often do the job, and larger or hidden systems get a visit.
Can we book visits on a schedule?

Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We’ll flag anything we notice during the clean.

Different parts, different methods
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
Why act early in Forty Green
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. Rural sites cannot always move to another kitchen or room when something fails.
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.
