AHU cleaning for kitchens and businesses in Owslebury Bottom
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. The work covers dampers and louvres, supply and extract fans and drain trays, and people most often call us about dirty coils holding back the airflow and leaves and litter drawn into the unit.
For a building in or near Owslebury Bottom, access is agreed in advance and the visit is planned around the journey.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Multi-site and managed buildings
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
Keeping the system healthy
Simple habits between visits make a real difference. Our advice:
- File each AHU report in the maintenance log
- Keep filter changes on time and recorded
- Book the next check in line with the report
- Clear leaves and litter away from the intake
The report suggests a date for the next inspection or clean, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
Staff cleaning versus specialist work
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
When it’s something else
To be straight with you, there are a few things this work will not fix:
- Ductwork downstream of the unit, which is a separate clean
- Damaged coils beyond cleaning
- Faulty motors, drives or bearings
If you are not sure, just call 0345 646 2711, or send details by email and we’ll give you a straight answer.
What the work covers
- Supply and extract fans
- Internal panels
- Dampers and louvres
- Drain trays

When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before any work starts.

Do you need AHU cleaning in Owslebury Bottom?
Air handling units are typically tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. Months can pass without anyone looking inside.
The symptoms we are asked about most are:
- Debris and leaves in the fresh air intake
- Dirty coils holding back the airflow
- Condensate trays that will not empty
- Rooms that smell stuffy when the system runs
If you manage a school such as Owslebury Primary School, ventilation cleaning is best booked for the holidays.
What to look for in a quote
- Proof of accreditation you can verify
- How they set the interval to the next visit
- Whether they’re fully insured
- What happens if part of the system cannot be accessed
The process
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, which takes one overnight shift for many single units, with bigger plant phased. If the van will struggle with a lane or gateway near Owslebury Bottom, let us know and we’ll plan around it.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Before we arrive
- Agree a time when the area can be out of use
- Mention any parking or loading restrictions
- Clear loose items from the work area

Here’s what helps us quote: the address, the type of site and when it’s open, a few photos and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711 or email us.

Owslebury Bottom questions
Can the work in Owslebury Bottom be done at night or at weekends?
Yes, we can come after you close and finish before you open. It means the site in Owslebury Bottom keeps running as normal. When you call us on 0345 646 2711 or send us an email, mention when the site is quiet.

Is there a survey before the work?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
How far ahead should we book?
The more notice, the better, especially for out-of-hours work. We typically quote within one working day, and emergencies are covered by our 24/7 line.
Are you fully insured?
Yes, we’re fully insured. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.
Can you look after several sites?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Each site gets its own report and photos.
What happens if you cannot reach some of it?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
