AHU cleaning in Funtington, done properly
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. Typical jobs include drain trays holding standing water and plant that has been serviced but not cleaned, across filter sections, drain trays 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.
We have 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.

How we price AHU cleaning
Your quote is based on your site. We take into account:
- Access, including roofs, risers and ceiling voids
- The condition of the system
- The times the site is available
- The scale of the work
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
What we need to know
A few details help us quote accurately. When you get in touch, it helps to send:
- Photos showing the whole system and its surroundings
- How we’d reach plant on a roof or in a plant room
- The times we could work without disrupting the site
- The postcode and the type of business
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before any work starts.
Part by part
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
Fans and fan sections
Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.
How it works
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes anything from half a day for one small unit to several shifts for a plant room full of them, and the area is cleaned down before we leave. A few photos of the system help us make the most of a visit to a place like Funtington.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Let us know about parking and loading
- Have your last certificate or report to hand
- Clear loose items from the work area
Getting a quote
There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, call 0345 646 2711 or send us an email.
Advice
What staff can safely do
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
What AHU cleaning can’t fix
A few issues sit outside what this work can do:
- The supply and extract ducts, quoted separately
- Controls and BMS settings that run the unit
- Airflow problems caused by the system’s design
Not sure which it is? You can call 0345 646 2711 or drop us a line and we’ll tell you honestly before booking.

Common problems we fix in Funtington
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and the finer material travels on.
Any of these means the system needs a check-up:
- Coils clogged with dust and debris
- Plant that needs cleaning after a refit
- Rooms that smell stuffy when the system runs
- Plant that has been serviced but not cleaned
Classrooms and halls at schools such as Funtington Primary School are easiest to work in when pupils are away.
