AHU cleaning in Steeple Aston, done properly
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. If you have dust-coated heating and cooling coils and dust built up on fan impellers, we can help, from drain trays, supply and extract fans and internal panels onwards.
For a building in or near Steeple Aston, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
We have been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Common problems we fix in Steeple Aston
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that’s the air they breathe for hours on end.
Look out for these warning signs:
- Air handling units with blocked filters
- Odours coming through the supply air
- Condensate trays that won’t empty
- Debris and leaves in the fresh air intake
For workplaces around Heyford station with mechanical ventilation, cleaning can be done in the evening or at weekends.
Questions to ask before you book
- Exactly which parts of the system are covered
- Whether a written report and pictures are included
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- What happens if part of the system cannot be accessed
What staff can safely do
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

What affects the cost of AHU cleaning
There’s no set price list, because no two systems are the same. The quote depends on:
- How easy every part is to reach

- The times the site is available
- How big the system is
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before we start.

Questions from Steeple Aston
Can the work in Steeple Aston be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. It means the site in Steeple Aston keeps running as normal. Let us know the hours you’re closed and we will book within them.
Is Steeple Aston in your area for AHU cleaning?
Yes, Steeple Aston is covered. Just call us on 0345 646 2711, or email photos with a few details of the site.
What happens to the waste?
We contain it and take it with us. We collect grease, debris and waste water as we go, so it doesn’t spread.
Do you work with multi-site operators?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Every site has its own report.
How long does an AHU clean take?
Cleaning takes a single shift for a typical unit, longer for large or heavily soiled ones. Bigger units can be phased, and you can ring 0345 646 2711 or use the quote form to plan it.
What’s included in an AHU clean?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.
Are you insured?
Yes, we are fully insured. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. At the end, the area is cleaned down.
Why act early in Steeple Aston
Leave an AHU uncleaned and the dirt doesn’t stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Planning a trip to Steeple Aston ahead is easier for everyone than a rushed one.
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 make a difference.

Facilities teams in offices, schools and healthcare sites book us too across Oxfordshire. Larger estates can be phased building by building around the people who use them.
What we do, step by step
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. The middle part takes longest, and that takes anything from half a day for one small unit to several shifts for a plant room full of them. We agree a date with you, plan the drive to Steeple Aston and turn up when the site is quiet.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- 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 permits to work or site inductions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Agree a time when the area can be out of use
