Review the system
We check photographs, opening hours, cooking type, previous reports and the extraction route.
Air Duct & AC Duct Cleaning in London
Duct Clean London cleans air ducts, air-conditioning ductwork and ventilation systems across London. We work in offices, shops, flats, houses, gyms and schools, and clean the whole route the air travels: the ducts themselves, the supply and extract ventilation, heat recovery (MVHR) units and the grilles and diffusers in each room.
Every job ends with a report and before and after photos, so you can see exactly what was inside your ducting and what it looks like once we have finished.
What we clean
- Air-conditioning ducts – the ductwork that carries cooled or heated air from the AC unit to each room.
- Supply and extract ventilation – ductwork that brings fresh air in and takes stale air out of the building.
- Heat recovery (MVHR) units – the unit and the ducting connected to it.
- Grilles and diffusers – the vents on walls and ceilings where air enters and leaves each room.
Buildings we work in
We clean air ducts and ventilation in offices, shops, flats and houses, gyms and schools. Commercial kitchens have their own grease extraction service; see kitchen extraction cleaning and kitchen air system cleaning.
How we clean your ductwork
- Survey. We look at the system, the duct route and the access points, or review photos you send us, and agree what will be cleaned.
- Before photos. We photograph the inside of the ducts and the vents before we start.
- Cleaning. We loosen dust and debris with brushes and compressed air, and remove it with vacuum equipment.
- Sanitising treatment. Where it is needed, we apply a sanitising treatment to the cleaned surfaces.
- After photos and report. You receive a report with before and after photos of the work.
Signs your air ducts may need cleaning
- Dust coming out of grilles or settling quickly around vents.
- A musty or stale smell when the air conditioning or ventilation runs.
- Weaker airflow from some vents than others.
- Visible dirt or debris on grilles, diffusers or inside the duct openings.
- Moving into a property, or the system not having been cleaned for a long time.
