How we price AHU cleaning
We do not publish a price list, because no two systems are the same. What we look at:
- The scale of the work
- When the work can happen, such as evenings, overnight or weekends
- Whether several sites go on one quote
- A single visit or a regular plan
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711 or drop us a line, and we will talk you through it.
What to send for a quote
You don’t need the technical terms. Just send:
- The postcode and the type of business
- Any access panels or hatches you can see
- When the site is open and when it’s quiet
- Problems your staff have spotted
For AHU cleaning in Dargate, phone us on 0345 646 2711 or drop us a line. Tell us what kind of premises it is and when it’s open, and send photos or your last report if you can. We usually send a fixed quote within one working day.
About our AHU cleaning in Dargate
If the units serving a building in Dargate have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. If you have dust built up on fan impellers and stale or musty smells from the ventilation, we can help, from filter sections, supply and extract fans and internal panels onwards.
For a building in or near Dargate, access is agreed in advance and the visit is planned around the journey.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Part by part
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.
Drain trays
The drain tray collects water from the cooling coil. Standing water and slime are removed and the outlet is checked.
In-house cleaning or a specialist?
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, alongside our reports.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Dargate: your questions answered
Can you come to Dargate after we close?
Yes, evening, overnight and weekend work is normal for us. The work in Dargate can fit around your hours. Just ring 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
Do you cover smaller places like Dargate?
Yes. Dargate is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you have insurance?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
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 we will suggest an interval after the first clean.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
Which accreditations do you hold?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we are fully insured.
Can you look after several sites?
Yes. You deal with one contact for every site in our area, and visits can be set on a regular cycle.

How it works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before any work starts, and floors and nearby surfaces are sheeted. On site, it takes a single shift for a typical unit, longer for large or heavily soiled ones. A quick note on how to find the site and where to park makes a visit to Dargate run smoothly.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Getting ready for the visit
- Arrange a key holder or contact on site
- Make sure equipment near the work can be switched off and left to cool
- Clear loose items from the work area
Ask for a quote
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. Then phone us on 0345 646 2711, or send details by email.

Signs you need AHU cleaning in Dargate
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
Clients normally contact us when they notice one of these:
- Units that have only ever had filter changes
- Dirty coils holding back the airflow
- Rooms that smell stuffy when the system runs
- Units needing a clean before a new tenant or handover
Classrooms and halls at schools such as Hernhill Church of England Primary School are easiest to work in when pupils are away.
