How we handle AHU cleaning in King's Somborne
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. Coils are cleaned carefully, with methods chosen so the fins are not flattened. The work covers internal panels, supply and extract fans and dampers and louvres, and people most often call us about leaves and litter drawn into the unit and drain trays holding standing water.
In a village or hamlet like King's Somborne, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Landlords, agents and facilities managers
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
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.
Signs you need AHU cleaning in King's Somborne
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
Any of these means the system needs a check-up:
- Debris and leaves in the fresh air intake
- Air handling units with blocked filters
- Condensate trays that won’t empty
- Dust built up on fan impellers
Wherever a school like King's Somborne Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

King's Somborne questions
Do you offer AHU cleaning in King's Somborne?
Yes. Our area runs across London and the South East, King's Somborne included. You can call us on 0345 646 2711 or drop us a line and let us know what needs doing.
Do you cover smaller places like King's Somborne?
Yes, we work in villages as well as towns, and King's Somborne is covered. The journey is planned ahead, so a few details about the route help.
Can you fix a faulty AHU?
The clean includes noting faults, but repairs sit with your maintenance contractor, with photos where it helps.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Each site gets its own report and photos.
What does AHU cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. We fix the price before any work starts.
Do you give a certificate after the clean?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
What your team can do, and what needs us
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
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’s where we come in.
Why act early in King's Somborne
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. Out of sight is the usual reason a rural system goes too long without attention.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
Why choose Duct Doctor in King's Somborne
- A written report with pictures after every visit
- Out-of-hours work and a 24/7 emergency line
- Survey first, then a fixed quote
- Fixed quotes, normally within one working day
How the job changes from site to site
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.

What affects the cost of AHU cleaning
The diagnosis comes before the price. We look at:
- The scale of the work
- The condition we find in the survey
- How easy every part is to reach
- Any permits to work or inductions
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and the price is agreed before work begins.

Photos and a few facts are often enough to price the work. Useful things to send:
- Your opening hours and when the area is out of use
- The roof, plant room or outside wall the system runs to
- Anything you’ve noticed, such as smells, noise, drips or poor airflow

What we do, step by step
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before any work starts, and the area around the work is covered and protected. On site, it takes half a day to a full day per unit, with large plant planned over several shifts. In a small place like King's Somborne, the journey is planned ahead and the visit arranged around the site’s hours.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos 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.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Mention any locked doors, roof access or ceiling voids
