For landlords and multi-site operators
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
How we handle AHU cleaning in South Stour
Where a building in South Stour has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. Common call-outs are for leaves and litter drawn into the unit and odours coming through the supply air, on filter sections, internal panels and drain trays.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
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’re fully insured.

When it’s something else
AHU cleaning can’t fix everything, and we’d rather say so up front. It does not solve:
- Building management system faults
- Breakdowns that need a mechanical engineer
- The supply and extract ducts, quoted separately
If you’re not sure, just call 0345 646 2711 or send us an email and we will give you a straight answer before you book.
What the work covers
- Supply and extract fans
- Filter sections
- Dampers and louvres
- Heating and cooling coils
- Internal panels
- Drain trays
What affects the cost of AHU cleaning
We don’t publish a price list, because no two systems are the same. What we look at:
- How easy every part is to reach
- Any permits to work or inductions
- Working hours and out-of-hours timing
- How big the system is
You won’t find a price list here, because each job is priced on what it involves. For a fixed quote, call us on 0345 646 2711 or drop us a line, and we will talk you through it.
Asking for a quote
Before you ask for a quote, gather:
- Detail shots of panels, filters and grilles
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any previous report or certificate
- Your opening hours and when the area is out of use

South Stour: your questions answered
Can you get to a site in South Stour?
Yes, we work in villages as well as towns, and South Stour is covered. The journey is planned ahead, so a few details about the route help.
Can the work in South Stour be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. That way a site in South Stour does not have to lose a day’s trading. Let us know the hours you’re closed and we’ll book within them.
What accreditations do you have?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.
Do you clean the ductwork as well?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can survey both on the same visit.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
What information do you need?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then call us on 0345 646 2711, or send details by email.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
How the job changes from site to site
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
Fans and fan sections
Dust on a fan impeller adds weight and wear. A clean fan runs more smoothly.
Ventilation in South Stour buildings
About 51 miles out from central London, South Stour is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site. William Harvey Hospital is the nearest hospital, about 2.4 miles north of South Stour. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
If you manage a school such as Finberry Primary School, ventilation cleaning is best booked for the holidays. Healthcare buildings such as William Harvey Hospital, about 2.4 miles north, depend on their ventilation; if you manage a surgery, clinic or care home near South Stour, yours matters too.
South Stour is about 3 miles south-east of Ashford, in Kent.

Looking after it afterwards
Here’s the after-treatment advice, in brief:
- Change filters on schedule and log each change
- Report musty smells from the vents right away
- Report water on the plant room floor
- File each AHU report in the maintenance log
Stick to the filter change schedule, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
Why deal with it now?
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. If the system at a site near South Stour fails, there may be nowhere nearby to move to.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.

How it works
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 photos. Most of the time goes on the work itself, which takes one overnight shift for many single units, with bigger plant phased. If you can send pictures, we can arrive in South Stour knowing what to expect.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures 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.
- We take after pictures and issue the certificate and report.
How to prepare
- Arrange a key holder or contact on site
- Clear the space around the work
- Make sure equipment near the work can be switched off and left to cool
Getting a quote
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before work begins.
