How we handle AHU cleaning in Abingdon-on-Thames
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. If you have air handling units never cleaned inside and dust-coated heating and cooling coils, we can help, from filter sections, heating and cooling coils and dampers and louvres onwards.
Around a town like Abingdon-on-Thames, the buildings with ducted ventilation are typically offices, schools, surgeries and care homes. Their supply and extract ducts all gather dust over time, and TR19® Air sets out how to inspect and clean them.
The sign-off is always in writing: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

What happens if it’s left?
Stuffy rooms and stale smells in a building in Abingdon-on-Thames can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. A small fault found now is a quick job; the same fault found later can close the site.
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered and we’ll price it together.

Part by part
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and clean the filter housing.
Keeping the system healthy
Results last longer with the right care. We suggest:
- Keep the certificate and photo report with the plant records
- Report stiff or damaged access doors
- Change filters on schedule and log each change
- Report musty smells from the vents straight away
Stick to the filter change schedule, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.

Landlords, agents and facilities managers
From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
We also work for facilities teams across offices, schools and healthcare in Abingdon-on-Thames and across Oxfordshire. Work can be phased by floor, building or site to keep disruption down.
What staff can safely do
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
What happens on the day
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. The middle part takes longest, which takes half a day to a full day per unit, with large plant planned over several shifts. Parking in a town like Abingdon-on-Thames is typically straightforward, so the main questions are access and timing.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Agree a time when the area can be out of use
- Tell us about site rules, permits or sign-in
- Allow time for equipment near the work to be turned off and cool down
