AHU cleaning for kitchens and businesses in Lydden
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. Common call-outs are for drain trays holding standing water and stale or musty smells from the ventilation, on supply and extract fans, heating and cooling coils and internal panels.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
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.

The process
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. A few pictures of the system help us make the most of a visit to a place like Lydden.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Agree a time when the area can be out of use
- Mention any sign-in, permit or induction we need
- Clear the space around the work
Ask for a quote
We do not publish a price list, because every site is different. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To start, phone us on 0345 646 2711 or drop us a line.

What else we do in Lydden
How we price AHU cleaning
There’s no set price list, because sites vary so much. What we look at:
- When the work can happen, such as evenings, overnight or weekends
- Site requirements such as sign-in and permits
- Parking and loading at the site
- The size of the system
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before work begins.
What to send for a quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Wide photos of the system and the area around it
- Any symptoms, from odd noises to smells or leaks
- The times we could work without disrupting the site
For AHU cleaning in Lydden, phone us on 0345 646 2711 or email us. Let us know the site type and the opening hours, plus photos or the previous report if they’re to hand. A fixed quote typically follows within one working day.
Signs you need AHU cleaning in Lydden
Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
The symptoms we are asked about most are:
- Plant that has been serviced but not cleaned
- Rooms that smell stuffy when the system runs
- Dirty filters cutting the airflow
- Dust built up on fan impellers
Hospitals such as Buckland Hospital (about 3.1 miles south-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Lydden are no different.

What AHU cleaning cannot fix
A few issues sit outside what this work can do:

- Coils that are corroded or leaking and need replacing
- Mechanical faults with motors, belts or bearings

Lydden: your questions answered
Can you get to a site in Lydden?
Yes. Villages and rural sites across the South East are part of our work, Lydden included. Just mention lanes, gates or anything else about the site when you book.
Is Lydden in your area for AHU cleaning?
Yes, Lydden is within the area we cover across London and the South East. To start, ring 0345 646 2711 or send us an email with a few photos of the system.
How long will the unit be out of action?
Cleaning takes from a few hours for a compact unit to a day or more for a large one. Bigger units can be phased, so give us a ring on 0345 646 2711 or drop us a line to talk it through.
Can you fix a faulty AHU?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report for your maintenance team to follow up.
Do you clean the ductwork as well?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
Do you give a certificate after the clean?
Yes, both a certificate and a report with pictures. It includes a recommended date for the next check.
Do you have insurance?
Yes, we are fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.
What about areas you can’t get to?
Anything we cannot reach goes on the report, with pictures where possible, and we explain what access is needed, for example new access panels.

Different parts, different methods
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
Multi-site and managed buildings
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so records stay tidy.
