AHU Cleaning in Bowsey Hill
We cover Bowsey Hill for AHU cleaning. Fixed quotes, work around your opening hours and photo reports on every job.
- Dirty coils holding back the airflow
- Odours coming through the supply air
- Plant that has been serviced but not cleaned
Keeping the system healthy
No system stays clean for ever, but care slows the build-up. A few tips:
- Store the TR19 paperwork where auditors can find it
- Make sure condensate is draining away
- Report musty smells from the vents right away
- Report stiff or damaged access doors
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
About our AHU cleaning in Bowsey Hill
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from pictures or a site visit, and give you a fixed quote before any cleaning starts. The work covers heating and cooling coils, drain trays and dampers and louvres, and people most often call us about dirty fans and fan housings and dirty coils holding back the airflow.
Work in a small place like Bowsey Hill starts with agreeing access and timings.
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’re fully insured.

What else we do in Bowsey Hill
Bowsey Hill: your questions answered
Can ventilation in schools around Bowsey Hill be cleaned out of term?
Yes, out-of-term visits are normal for schools. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Bowsey Hill. Send us your term dates when you phone us on 0345 646 2711, or send details by email, and we’ll fit the work in.
Can you get to a site in Bowsey Hill?
Yes. Villages and rural sites across the South East are part of our work, Bowsey Hill included. The journey is planned ahead, so a few details about the route help.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before we start, and anything we remove is contained. At the end, the area is cleaned down.
Can you clean the AHU out of hours?
Yes. Evening, overnight and weekend work is all possible, so the building keeps running in the day.
Are you accredited?
Duct Doctor is 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.
Do you clean the ductwork as well?
Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can survey both on the same visit.
What does TR19 mean?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
What if parts of the system cannot be reached?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.
What we’re called out for in Bowsey Hill
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
If you notice any of these, it’s worth a diagnosis:
- Blocked condensate drains and slimy trays
- Units that have only ever had filter changes
- Fan sections that haven’t been cleaned in years
- Odours coming through the supply air
For schools like Crazies Hill CofE Primary School, the holidays are the usual time to inspect and clean ventilation.
Questions to ask before you book
- What insurance they carry
- What’s included in the scope, part by part
- What hours they’ll be on site
- Whether inaccessible sections are listed on the report
How the visit works
We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. From there, it 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 Bowsey Hill and turn up when the site is quiet.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Allow time for equipment near the work to be turned off and cool down
- Mention any parking or loading restrictions
- Let us know how we reach the system, including roofs, risers and plant rooms

What your team can do, and what needs us
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
What a clean won’t put right
In fairness, there are a few things this work will not fix:
- Leaking heating or cooling coils
- Breakdowns that need a mechanical engineer
- Problems with the unit’s controls or sensors
If in doubt, call 0345 646 2711, or email photos and we’ll say what we think.
What the work covers
- Heating and cooling coils

- Dampers and louvres
Why act early in Bowsey Hill
Leave an AHU uncleaned and the dirt doesn’t stay put. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. In a small place like Bowsey Hill, a system that fails can take a site out of use.
