Oxfordshire · Air handling unit cleaning
Air handling unit cleaning in Weald, Oxfordshire
We cover Weald for cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces. Out-of-hours visits, a fixed quote and a written report with pictures as standard.
- Blocked condensate drains and slimy trays
- Filters that are clogged or overdue
- Fan sections that haven’t been cleaned in years
What the work involves, part by part
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
About our AHU cleaning in Weald
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. Typical jobs include dirty coils holding back the airflow and dirty fans and fan housings, on drain trays, dampers and louvres and filter sections.
Work in a small place like Weald starts with agreeing access and timings.
A written report with pictures follows every visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Why it’s worth doing now in Weald
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. Equipment tucked in a roof space or outbuilding near Weald rarely gets looked at unless someone books it.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, call 0345 646 2711 or email us for straight advice and a fixed quote.
Why book with us
- Fixed quotes from a survey or pictures
- We diagnose before we treat
- One number for every site across the South East and London
- Full insurance on every job
Keeping the system healthy
Results last longer with the right care. We suggest:
- Report water on the plant room floor
- Report stiff or damaged access doors
- Check the drain tray is emptying during routine visits
- Flag stale or damp smells in the supply air
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
Managing agents and facilities teams in Weald
We regularly work with managing agents. Send the address, what’s needed and how access works, and we will send a fixed quote.
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 to a regular schedule.
Common questions in Weald
Can the work in Weald be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Weald needn’t be disturbed. Your opening times are the first thing we ask for.
Do you cover Weald for AHU cleaning?
Yes, Weald is covered. To start, call 0345 646 2711, or email photos with a few photos of the system.
Which kinds of sites do you work on?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
What happens if you can’t reach some of it?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, along with a quote to put access in.
How far ahead should we book?
The more notice, the better, particularly for night and weekend visits. We usually quote within one working day, and emergencies are covered by our 24/7 line.
How do you protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Do you work with multi-site operators?
Yes. We work across South East England and London, so we can schedule a run of sites on one programme. Each site gets its own report and photos.
When should our AHU next be cleaned?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and the report recommends a next date.

What we are called out for in Weald
Filters that are not changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
The symptoms we’re asked about most include:
- Fan sections that haven’t been cleaned in years
- Intake sections clogged with outdoor debris
- Units that have only ever had filter changes
- Dirty coils holding back the airflow
If you run a surgery, dental practice or care home near Weald, clean ventilation matters as much to you as to a hospital like Longworth Hospital (about 4.3 miles south).
What your quote should include
- Whether the figure could change on the day
- When the next visit should be, and why
- Whether the quote shows VAT
- What paperwork you get at the end
What happens on the day
Each visit runs to the same pattern: sheeting and protection first, make the system safe, carry out the AHU cleaning, clear away and hand over the paperwork. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Photos of the system and how to reach it help us plan a visit to Weald.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Clear loose items from the work area
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

How we price AHU cleaning
The survey tells us what the work involves. The main factors are:
- A single visit or a regular plan
- What state the system is in
- When the work can happen, such as evenings, overnight or weekends
- Site requirements such as sign-in and permits
What you pay depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before we start, so there are no surprises.
What we need to know
Before you ask for a quote, gather:
- Wide pictures of the system and the area around it
- The paperwork from the last visit, if you have it
- Close-ups of filters, grilles, hatches or access panels
- How we’d reach plant on a roof or in a plant room
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
