AHU cleaning in Flishinghurst, done properly
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. If you have debris and leaves in the fresh air intake and drain trays holding standing water, we can put it right, from drain trays, filter sections and heating and cooling coils onwards.
Work in a small place like Flishinghurst starts with agreeing access and timings.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Managing agents and facilities teams in Flishinghurst
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
Keeping the system healthy
To keep the system working properly between visits:
- Look at the condensate drain whenever the unit is serviced
- Diary the inspection date recommended in the report
- Keep the certificate and photo report with the plant records
- Clear leaves and litter away from the intake
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
Common questions in Flishinghurst
Can you work in Flishinghurst outside opening hours?
Yes, out-of-hours work is a big part of what we do. That way a site in Flishinghurst doesn’t have to lose a day’s trading. Let us know the hours you’re closed and we’ll book within them.
Do you cover Flishinghurst for AHU cleaning?
Yes. Our area runs across London and the South East, Flishinghurst included. To start, phone us on 0345 646 2711, or email photos with a few pictures of the system.
How do you keep the site clean during the work?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
When should our AHU next be cleaned?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and the report recommends a next date.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
How long does an AHU clean take?
It takes anything from half a day for one small unit to several shifts for a plant room full of them. The unit’s size and condition make the biggest difference, and we’ll confirm the time when we quote.
How much does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we’ll typically reply within one working day.
Do you survey before quoting?
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.

Staff cleaning versus specialist work
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.

Flishinghurst’s nearest hospital, Benenden Hospital, is about 5 miles east. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.

What we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, 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. Rural roads and tight entrances are worth telling us about before a visit to Flishinghurst.
- We survey the unit from photos or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.

Ask for a quote

What the work involves, part by part
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. We clean the impeller, housing and surrounding section.
