What we do, step by step
A visit follows the same order every time: sheeting and protection first, make the system safe, do the work, tidy up and leave you the report. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. A few pictures of the system help us make the most of a visit to a place like Hambledon.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Name a contact who can let us in at the agreed time
- Move anything stored near the system
- Tell us the best time to work, such as after service or at a weekend
How to get a quote
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.

AHU cleaning for kitchens and businesses in Hambledon
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from pictures or on site, followed by a fixed quote before any cleaning starts. If you are dealing with leaves and litter drawn into the unit and dust built up on fan impellers, we can put it right.
In a village or hamlet like Hambledon, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Different parts, different methods
Internal casing and panels
We open each section through its doors and close them securely when we are done before the unit is handed back.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.
Questions from Hambledon
Is AHU cleaning available in Hambledon?
Yes, we work in Hambledon and the places around it. Just ring 0345 646 2711, or email photos with a few details of the site.
Do you cover smaller places like Hambledon?
Yes, we work in villages as well as towns, and Hambledon is covered. Just mention lanes, gates or anything else about the site when you book.
What’s included in an AHU clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. We confirm the scope after looking at the unit.
Do you work with multi-site operators?
Yes. We work across South East England and London, so we can schedule a run of sites on one programme. Every site has its own report.
Do you give a certificate after the clean?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
Do you look at the system first?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
How we price AHU cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The size of the system
- The times the site is available
- The condition of the system
- Parking and loading at the site
The cost depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.
Helping us quote
To speed up the quote, please include:
- The site address and the type of premises
- Your last certificate, test record or report

Why it’s worth doing now in Hambledon
A clean unit feeds cleaner air into the ductwork, so the whole system stays cleaner for longer. That makes the next inspection of a building in Hambledon simpler. Systems in rural buildings are often out of sight and out of mind.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before we start.
Why choose Duct Doctor in Hambledon
- Survey first, then a fixed quote
- Fixed quotes from a survey or pictures
- Accredited under CHAS and SafeContractor, with ISO 9001
- Trading since 2009

Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Flag stale or damp smells in the supply air
- Keep the area around the fresh air intake clear
- Book the next check in line with the report
- File each AHU report in the maintenance log
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
Managing agents and facilities teams in Hambledon
Records are where multi-site compliance often slips. Each visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
When something else is needed
AHU cleaning cannot fix everything, and we’ll tell you before work begins. It does not solve:
- Dirty ducts beyond the unit itself
- Leaking heating or cooling coils
- Airflow problems caused by the system’s design
Not sure which it is? You can call us on 0345 646 2711 or use the quote form and we’ll tell you honestly before booking.
