- Drain trays holding standing water
- Stale or musty smells from the ventilation
- Air handling units never cleaned inside
Between visits
Here’s the after-treatment advice, short and simple:
- Diary the inspection date recommended in the report
- Store the TR19 paperwork where auditors can find it
- Keep the area around the fresh air intake clear
- Stick to the filter change plan
When we’ve closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
AHU cleaning in Selborne
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. We’re often asked to deal with odours coming through the supply air and coils clogged with dust and debris, on dampers and louvres, internal panels and supply and extract fans.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

For schools like Selborne Church of England Primary School, the holidays are the usual time to inspect and clean ventilation.

What AHU cleaning can’t fix
It’s worth knowing the limits before booking:
- Coils that are corroded or leaking and need replacing
- Breakdowns that need a mechanical engineer
- Ventilation that was badly designed in the first place

Parts of the system we cover
- Drain trays
- Heating and cooling coils
- Internal panels
- Dampers and louvres
- Supply and extract fans

What we do, step by step
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes half a day to a full day per unit, with large plant planned over several shifts. We agree a date with you, plan the drive to Selborne and turn up when the site is quiet.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Preparing for the visit

Related advice
What the work involves, part by part
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that will not bend or flatten the fins.
Fans and fan sections
Dust on a fan impeller adds weight and wear. A clean fan runs more smoothly.
What staff can safely do
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
Selborne questions
Can you get to a site in Selborne?
Yes. Selborne is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do AHU cleaning in Selborne?
Yes, we work in Selborne and the places around it. Just give us a ring on 0345 646 2711 or email us with a few details of the site.
Is there a survey before the work?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
Will you repair the fan or motor?
We clean the unit and flag faults rather than repair them, with the details in the report.
Is a quote from pictures possible?
Normally, yes. Send a few wide photos plus close-ups of panels, filters or grilles, and a fixed quote typically follows within one working day. If photos are not enough, we will survey first.
How much notice do you need?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
How often should an air handling unit be cleaned?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
Do you offer emergency callouts?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we’ll talk you through the next steps.
Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
Why act early in Selborne
If people in a building in Selborne complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. Equipment tucked in a roof space or outbuilding near Selborne rarely gets looked at unless someone books it.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before work begins.
