AHU cleaning in Gay Bowers, done properly
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. The work covers supply and extract fans, filter sections and dampers and louvres, and common reasons people get in touch are rooms that smell stuffy when the system runs and filters that are clogged or overdue.
In a village or hamlet like Gay Bowers, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

What happens if it’s left?
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. If the system at a site near Gay Bowers fails, there may be nowhere nearby to move to.
What you pay reflects the actual work. That’s why every job is surveyed first, and why the quote is fixed before any work starts.

Part by part
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
Drain trays
Older trays can corrode and start leaking. Their condition goes into the report with pictures so you can decide on any repairs.
What AHU cleaning cannot fix
Some problems need a different service or another trade:
- Airflow problems caused by the system’s design
- Leaking heating or cooling coils
- Problems with the unit’s controls or sensors
If you are not sure, just phone us on 0345 646 2711, or email photos and we will give you a straight answer before you book.
Where we work
- Internal panels
- Dampers and louvres
- Supply and extract fans
- Filter sections
- Heating and cooling coils
- Drain trays
Looking after it afterwards
To keep the system working properly between visits:
- Change filters on schedule and log each change
- Make sure condensate is draining away
- Clear leaves and litter away from the intake
- Plan the next inspection before the last report gets filed away
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.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
The process
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. The middle part takes longest, which takes a single shift for a typical unit, longer for large or heavily soiled ones. If the van will struggle with a lane or gateway near Gay Bowers, let us know and we will plan around it.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Have your last certificate or report to hand
- Tell us about site rules, permits or sign-in
Ask for a quote
Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.

What else we do in Gay Bowers
Multi-site and managed buildings
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
When to call us in Gay Bowers
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that’s where slime and odours start.
What we are most often called out for:
- Condensate trays that won’t empty
- Stale or musty smells from the ventilation
- Air handling units never cleaned inside
- Dust-coated heating and cooling coils
School buildings such as Priory Primary School are typically done in the holidays, so classrooms aren’t disturbed.

Common questions in Gay Bowers
Can you come to Gay Bowers after we close?
Yes, out-of-hours work is a big part of what we do. It means the site in Gay Bowers keeps running as normal. Tell us your opening hours when you ask for a quote.
Can ventilation in schools around Gay Bowers be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. There are about 5 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Gay Bowers. Send us your term dates when you call us on 0345 646 2711, or send details by email, and we’ll fit the work in.
Will we get paperwork for the AHU clean?

Do you have a 24/7 line?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
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.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
How long will the unit be out of action?
Typically the clean takes from a few hours for a compact unit to a day or more for a large one. We plan the shutdown around that, out of hours if needed.
Do you have insurance?
Yes. We carry full insurance and have been trading since 2009.
