AHU Cleaning in Aston Upthorpe
AHU cleaning for Aston Upthorpe, from a team that has been trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Intake sections clogged with outdoor debris
- Plant that has been serviced but not cleaned
- Dirty filters cutting the airflow
Different parts, different methods
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.
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 Aston Upthorpe
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. The work covers drain trays, dampers and louvres and internal panels, and common reasons people get in touch are blocked condensate drains and slimy trays and leaves and litter drawn into the unit.
For a building in or near Aston Upthorpe, 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.
Good records are part of the job. You get a written report with photos after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

What happens if it’s left?
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. Rural sites cannot always move to another kitchen or room when something fails.
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, call 0345 646 2711 or drop us a line for straight advice and a fixed quote.

What your team can do, and what needs us

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.

How the visit works
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes from a few hours for a compact unit to a day or more for a large one. If the van will struggle with a lane or gateway near Aston Upthorpe, let us know and we’ll plan around it.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Allow time for equipment near the work to be turned off and cool down
