AHU Cleaning in Owslebury
AHU cleaning in Owslebury from ventilation hygiene specialists trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Coils clogged with dust and debris
- Plant that needs cleaning after a refit
- Fan sections that haven’t been cleaned in years
What staff can safely do
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and give you a fixed quote.
AHU cleaning in Owslebury, done properly
Our AHU cleans for sites in Owslebury cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after pictures in a report. If you have rooms that smell stuffy when the system runs and drain trays holding standing water, we can put it right, from filter sections, dampers and louvres and internal panels onwards.
Work in a small place like Owslebury starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

How the visit works
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. On site, it takes anything from half a day for one small unit to several shifts for a plant room full of them. The timing of a visit to Owslebury is set by you, and the travel is our side of the planning.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Dig out any earlier paperwork for the system

Part by part
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
When to call us in Owslebury
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. It’s easy for a long time to go by without anyone opening the panels.
The symptoms we are asked about most are:
- Rooms that smell stuffy when the system runs
- Units that have only ever had filter changes
- Air handling units due a clean after building work
- Condensate trays that won’t empty
Healthcare buildings such as St John's Rooms And Chapel, about 4 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Owslebury, yours matters too.

Why act early in Owslebury

Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, phone us on 0345 646 2711 or use the quote form and we’ll give you an honest view and a fixed quote.
