Do you need AHU cleaning in Hundridge?
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Hundridge, that is air they breathe for hours at a time.
Clients typically contact us after spotting something like this:
- Dirty fans and fan housings
- Air handling units never cleaned inside
- Coils clogged with dust and debris
- Odours coming through the supply air
Classrooms and halls at schools such as Hyde Heath Infant School are easiest to work in when pupils are away.

How we handle AHU cleaning in Hundridge
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. If you have dust-coated heating and cooling coils and air handling units never cleaned inside, we can help, from internal panels, filter sections and supply and extract fans onwards.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Each visit ends with a written report and photos, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How we price AHU cleaning
You’ll get a fixed price before any work starts. It’s based on:
- Working hours and out-of-hours timing
- Site rules, permits and inductions
- The scale of the work
- Access, including roofs, risers and ceiling voids
What you pay depends on the size of the system, the condition it’s in and access to every part of it. We give you a fixed price before work begins, so you know where you stand.

What staff can safely do
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.

From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
The process
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Photos of the system and how to reach it help us plan a visit to Hundridge.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Mention any sign-in, permit or induction we need
- Make sure someone can let us in and lock up afterwards
- Move anything stored near the system
How to get a quote
We don’t publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then give you a fixed quote. To start, call 0345 646 2711 or use the quote form.

Common questions in Hundridge
Can ventilation in schools around Hundridge be cleaned out of term?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 5 schools and colleges with food registrations within roughly a mile and a half of Hundridge. Booking early in the term gives the best choice of holiday dates.
Is Hundridge within the area you cover?
Yes, we work in villages as well as towns, and Hundridge is covered. Just mention lanes, gates or anything else about the site when you book.
When should our AHU next be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. We’ll tell you after the survey whether the ducts need it.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
What is TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
Can you price the work without visiting?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Why deal with it now?
If people in a building in Hundridge complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. Planning a trip to Hundridge ahead is easier for everyone than a rushed one.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we’ll price it together.

What the work involves, part by part
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with pictures.
