- Air handling units due a clean after building work
- Rooms that smell stuffy when the system runs
- Dust built up on fan impellers
What happens on the day
Each visit runs to the same pattern: protect the area, isolate whatever needs isolating, do the work, clear away and hand over the paperwork. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Visits to a village like Upper Bush are booked in advance, at a time that suits whoever runs the site.
- We survey the unit from pictures or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Let us know when the site is closed or quiet
- Mention any locked doors, roof access or ceiling voids
- Tell us where we can park and unload

AHU cleaning for kitchens and businesses in Upper Bush
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. The work covers filter sections, drain trays and dampers and louvres, and the jobs we see most are air handling units never cleaned inside and air handling units with blocked filters.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

What we’re called out for in Upper Bush
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that is where slime and odours start.
Signs it’s time to call us include:
- Air handling units due a clean after building work
- Units that have only ever had filter changes
- Leaves and litter drawn into the unit
- Stale or musty smells from the ventilation
If you run a surgery, dental practice or care home near Upper Bush, clean ventilation matters as much to you as to a hospital like French Hospital (about 3.2 miles east).

How we price AHU cleaning
We don’t publish a price list, because no two systems are the same. What we look at:
- The size of the system
- Where the site is and how we reach it
- Access, including roofs, risers and ceiling voids
- Whether it’s a one-off visit or part of a schedule
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before we start.
What we need to know
When you contact us, it’s useful to have:
- A few general shots of the system
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any symptoms, from odd noises to smells or leaks
- Detail shots of panels, filters and grilles

Part by part
Fans and fan sections
Dust on a fan impeller adds weight and wear. A clean fan runs more smoothly.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. Cleaning restores the open path through the fins.
Looking after it afterwards
Simple habits between visits make a real difference. Our advice:
- Keep inspection doors on the unit in good order
- Report musty smells from the vents straight away
- Plan the next inspection before the last report gets filed away
- Make sure condensate is draining away
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can survey both.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
Upper Bush: your questions answered
Is AHU cleaning available in Upper Bush?
Yes. We work across London and the South East, and Upper Bush is part of that. To start, call us on 0345 646 2711, or email photos with a few photos of the system.
Do you work in villages like Upper Bush?
Yes, Upper Bush is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Can you come out in an emergency?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
How far ahead should we book?
For planned work, earlier is better, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.
What does TR19 mean?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
Are you insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Is there a report after cleaning?
Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.
Leave it or put it right?
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. If the system at a site near Upper Bush fails, there may be nowhere nearby to move to.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will go through it with you.
