AHU cleaning in Luddesdown, done properly
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. The work covers supply and extract fans, heating and cooling coils and filter sections, and people most often call us about leaves and litter drawn into the unit and dirty filters cutting the airflow.
Work in a small place like Luddesdown starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
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 are fully insured.

What the work involves, part by part
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. Access is planned during the survey, before we quote.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
Multi-site and managed buildings
Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
The process
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes from a few hours for a compact unit to a day or more for a large one. The timing of a visit to Luddesdown is set by you, and the travel is our side of the planning.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Name a contact who can let us in at the agreed time
- Find the previous report, if there is one

What affects the cost of AHU cleaning
Sites vary more than people expect. The main factors:
- A single visit or a regular plan
- When the work can happen, such as evenings, overnight or weekends
- Whether several sites go on one quote
- The condition of the system
You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.
What we need to know
Photos and a few facts are often enough to price the work. Send what you can of the following:
- The times we could work without disrupting the site
- How we’d reach plant on a roof or in a plant room
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Photos showing the whole system and its surroundings
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.
Do you need AHU cleaning in Luddesdown?
Wherever there’s a cooling coil, there’s condensate. 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.
It’s time to book a visit if you see:
- Fan sections that haven’t been cleaned in years
- Drain trays holding standing water
- Air handling units never cleaned inside
- Intake sections clogged with outdoor debris
If you manage a school such as Meopham School, ventilation cleaning is best booked for the holidays.
Comparing quotes

- What happens if part of the system cannot be accessed
- How VAT is shown on the quote
- What hours they’ll be on site
What happens if it’s left?
Dirt left in an air handling unit doesn’t stay in the unit. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. It’s simpler to plan the work at Luddesdown now than to arrange it in a hurry later.
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before work begins.

Your questions about AHU cleaning in Luddesdown
Do you clean school ventilation in Luddesdown in the holidays?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Luddesdown. Send us your term dates when you ring 0345 646 2711, or send details by email, and we’ll fit the work in.
Can you work in Luddesdown outside opening hours?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.
Can you look after several sites?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
How often should an air handling unit be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. Each report suggests when the unit should next be looked at.
How long does an AHU clean take?
As a guide, it takes half a day to a full day per unit, with large plant planned over several shifts. The shutdown is planned to fit, out of hours if needed.
Can you quote from pictures?
Typically, yes. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote usually follows within one working day. If pictures are not enough, we will survey first.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
What do you do to protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
