Oxfordshire · Air handling unit cleaning
Long Hanborough AHU cleaning
AHU cleaning across Long Hanborough and nearby, timed so the site keeps working and signed off in writing with photos.
- Rooms that smell stuffy when the system runs
- Intake sections clogged with outdoor debris
- Air handling units never cleaned inside
Aftercare tips
Once we’ve finished, these simple steps help:
- Report water on the plant room floor
- Keep filter changes on time and recorded
- Book the next check in line with the report
- Keep the certificate and photo report with the plant records
The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
How we handle AHU cleaning in Long Hanborough
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from photos or a site visit, and give you a fixed quote before any cleaning starts. If you’re dealing with units needing a clean before a new tenant or handover and leaves and litter drawn into the unit, we can help.
Around a place like Long Hanborough, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How the job changes from site to site
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.

Managing agents and facilities teams in Long Hanborough
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
What we are called out for in Long Hanborough
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
Clients usually contact us when they notice something like this:
- Air handling units with blocked filters
- Blocked condensate drains and slimy trays
- Odours coming through the supply air
- Dirty coils holding back the airflow
For workplaces around Combe station with mechanical ventilation, cleaning can be done in the evening or at weekends.

What we do, step by step
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. The work itself takes from a few hours for a compact unit to a day or more for a large one. Visits to a place like Long Hanborough are planned ahead, so we arrive with what the survey says the job needs.
- The survey covers the unit, its access and how it can be shut down.
- 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
- Have your last certificate or report to hand
- Tell us the best time to work, such as after service or at a weekend

Advice
Common questions in Long Hanborough
Do you cover smaller places like Long Hanborough?
Yes. Long Hanborough is within the area we cover across London and the South East. A survey first, from photos or a visit, means we arrive with the right kit.
Can you work in Long Hanborough outside opening hours?
Yes, out-of-hours work is a big part of what we do. It means the site in Long Hanborough keeps running as normal. Your opening times are the first thing we ask for.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
Is there a survey before the work?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Are you fully insured?
Yes. We carry full insurance and have been trading since 2009.
What happens if you can’t reach some of it?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
How much notice should we give?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
In-house cleaning or a specialist?
Logging matters as much as cleaning. 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. Cleaning inside ducts and units is specialist work.
