AHU cleaning in Lympne
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with photos, so the report shows exactly what was done. Typical jobs include dust built up on fan impellers and air handling units never cleaned inside, on drain trays, filter sections and supply and extract fans.
Somewhere as small as Lympne, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Duct Doctor has been trading since 2009, and we’re 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.

Lympne buildings and their air
Lympne, about 57 miles from central London, is within our usual area. The visit is fixed around your opening hours, not ours.
In Lympne, we look inside the system before deciding what needs cleaning.

Lympne: your questions answered
Is Lympne within the area you cover?
Yes. Lympne 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.
Is AHU cleaning available in Lympne?
Yes, we work in Lympne and the places around it. Just call 0345 646 2711, or email photos with a few details of the site.
Will you repair the fan or motor?
The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
What does TR19 mean?
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 law, but it’s the benchmark.
Do you do ventilation duct cleaning too?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can quote for both.
How long does it take to clean an air handling unit?
Cleaning takes anything from half a day for one small unit to several shifts for a plant room full of them. Large plant can be split over several shifts, so give us a ring on 0345 646 2711, or email photos to talk it through.
Common problems we fix in Lympne
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, a little more each month.
Signs it’s time to call us include:
- Blocked condensate drains and slimy trays
- Coils clogged with dust and debris
- Air handling units never cleaned inside
- Air handling units with blocked filters
Wherever a school like Lympne Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
What to look for in a quote
- Which accreditations they hold, and whether you can check them
- Whether the quote shows VAT
- Whether a survey comes first
- How they set the interval to the next visit
What a clean will not put right
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It won’t put right:
- Dirty ducts beyond the unit itself
- Building management system faults
- Airflow problems caused by the system’s design
If you are not sure, just phone us on 0345 646 2711, or send details by email and we’ll give you a straight answer.

What affects the quote in Lympne
Every site gets its own quote. These are the things that affect it:
- Site requirements such as sign-in and permits
- The condition we find in the survey
- How big the system is
- How many systems or sites are involved
We don’t list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.
What we need to know
To help us quote quickly, please include:
- The times we could work without disrupting the site
- Any access panels or hatches you can see
- The paperwork from the last visit, if you have it
- Photos showing the whole system and its surroundings
Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before we start.
How the visit works
A visit follows the same order every time: sheeting and protection first, make the system safe, carry out the AHU cleaning, clear away and hand over the paperwork. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. The timing of a visit to Lympne is set by you, and the travel is our side of the planning.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after pictures.
Preparing for the visit
- Agree a time when the area can be out of use
- Find the previous report, if there is one
- Make sure someone can let us in and lock up afterwards
Ask for a quote
There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, ring 0345 646 2711 or drop us a line.

What else we do in Lympne
Aftercare tips
Aftercare is simple, and it helps at the next visit:
- File each AHU report in the maintenance log
- Keep the area around the fresh air intake clear
- Make sure the unit’s access doors open easily
- Note any water around the unit or leaks below it
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
Multi-site and managed buildings
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
What your team can do, and what needs us
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
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.
