How we handle AHU cleaning in Witney
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. Typical jobs include odours coming through the supply air and filters that are clogged or overdue, on dampers and louvres, filter sections and heating and cooling coils.
Buildings in towns like Witney often have ventilation added in stages, with units on the roof or in a plant room. An inspection shows which parts need cleaning.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Why deal with it now?
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. A small fault found now is a quick job; the same fault found later can close the site.
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before work begins.
Why us?
- Full insurance on every job
- Fixed quotes, typically within one working day
- One number for every site across the South East and London
- Photo reports with every job

Managing agents and facilities teams in Witney
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
Part by part
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and the housing around them is cleaned too.
Fans and fan sections
Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.
What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
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.
What we are called out for in Witney
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
These are the problems we see most often:
- Odours coming through the supply air
- Air handling units never cleaned inside
- Drain trays holding standing water
- Intake sections clogged with outdoor debris
In Witney, we look inside the system before deciding what needs cleaning.
What your quote should include
- Whether the price is fixed
- How VAT is shown on the quote
- Whether inaccessible sections are listed on the report
- If they look at the system before pricing
Fixed quotes for AHU cleaning in Witney
The quote reflects the site in front of us. We take into account:
- One-off work versus a regular cycle
- How easy every part is to reach
- Whether several sites go on one quote
- Where the site is and how we reach it
What you pay depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before work begins, so there are no surprises.
Helping us quote
We can often survey from pictures. Try to include:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The paperwork from the last visit, if you have it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any access panels or hatches you can see
Photos are enough for some jobs, while others need a look on site. 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.
