Signs you need AHU cleaning in Wootton
Whatever surrounds a building in Wootton, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and some travels further into the unit.
Look out for these warning signs:
- Dirty fans and fan housings
- Dirty filters cutting the airflow
- Units needing a clean before a new tenant or handover
- Intake sections clogged with outdoor debris
For schools like Dry Sandford Primary School, the holidays are the usual time to inspect and clean ventilation.

AHU cleaning in Wootton
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. Typical jobs include blocked condensate drains and slimy trays and dirty filters cutting the airflow, across filter sections, dampers and louvres and supply and extract fans.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
For insurers and inspectors, the record counts. That is why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Honest limits
We’ll always give you a straight diagnosis, so here’s what AHU cleaning won’t do:
- The supply and extract ducts, quoted separately
- Building management system faults
- Coils that are corroded or leaking and need replacing
Not sure which it is? You can give us a ring on 0345 646 2711, or send details by email and we’ll tell you honestly.
Where we work
- Supply and extract fans
- Dampers and louvres
- Heating and cooling coils
- Internal panels
- Filter sections
- Drain trays
What staff can safely do
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Between visits
No system stays clean for ever, but care slows the build-up. A few tips:
- Don’t ignore odours coming through the grilles
- Keep the certificate and photo report with the plant records
- Report stiff or damaged access doors
- Note any water around the unit or leaks below it
We recommend when the unit should next be inspected or cleaned, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
How the visit works
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. The visit takes from a few hours for a compact unit to a day or more for a large one. We agree a date with you, plan the drive to Wootton and turn up when the site is quiet.
- 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.
- After pictures are taken and the certificate issued.
Getting ready for the visit

Advice
What the work involves, part by part
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey, before we quote.

What else we do in Wootton
What affects the cost of AHU cleaning
There’s no set price list, because no two systems are the same. The quote depends on:
- The number of sites or systems
- How big the system is
- Whether we need access equipment or extra panels
- One-off work versus a regular cycle
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, give us a ring on 0345 646 2711 or email us for straight advice and a fixed quote.
What to send for a quote
Photos let us diagnose from a distance. The most useful are:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your opening hours and when the area is out of use
- Any access panels or hatches you can see
- The paperwork from the last visit, if you have it
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To get going, give us a ring on 0345 646 2711 or send us an email.
