Oxfordshire · Air handling unit cleaning
Air handling unit cleaning in Nuffield, Oxfordshire
One call covers air handling unit cleaning in Nuffield, from survey to sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Leaves and litter drawn into the unit
- Dust built up on fan impellers
- Dirty coils holding back the airflow
What the work involves, part by part
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with pictures.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
AHU cleaning in Nuffield, done properly
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. The work covers heating and cooling coils, filter sections and dampers and louvres, and common reasons people get in touch are units that have only ever had filter changes and dirty fans and fan housings.
Somewhere as small as Nuffield, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
The paperwork matters as much as the work. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Staff cleaning versus specialist work
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Multi-site and managed buildings
Facilities teams in offices, schools and healthcare sites book us too in Nuffield and across Oxfordshire. Larger estates can be phased building by building around the people who use them.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
What we’re called out for in Nuffield
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
These are the problems we see most often:
- Odours coming through the supply air
- Plant that needs cleaning after a refit
- Coils clogged with dust and debris
- Dirty filters cutting the airflow
In Nuffield, we look inside the system before deciding what needs cleaning.

Aftercare tips
Think of this as the after-treatment advice, short and simple:
- Keep the area around the fresh air intake clear
- Look at the condensate drain whenever the unit is serviced
- Report stiff or damaged access doors
- Plan the next inspection before the last report gets filed away
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
The process
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. Pictures of the system and its access let us plan the work in Nuffield before we set off.
- 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.
How to prepare
- Mention any sign-in, permit or induction we need
- Clear the space around the work
- Let us know how we reach the system, including roofs, risers and plant rooms

What affects the quote in Nuffield
The diagnosis comes before the price. We look at:
- What state the system is in
- How many systems or sites are involved
- A single visit or a regular plan
- Any permits to work or inductions
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 any work starts, so there are no surprises.

- Any access panels or hatches you can see
- Wide photos of the system and the area around it
