The Unico Small-Duct HVAC System
Instead of traditional large metal ducts, Unico uses small, flexible, insulated tubes that weave easily through tight ceiling voids, floor cavities, and partition walls. It delivers heating, cooling, and ventilation through subtle, customisable outlets that can be matched to your wood floors or painted to disappear into your ceilings. Because it operates on an aspirating airflow principle, it gently mixes the air in the room, creating an incredibly even temperature without the drafts commonly associated with conventional air conditioning. It is the perfect hidden climate solution.
How the James Hargreaves Low Carbon Team Can Help Small-duct systems require precise engineering, and the James Hargreaves Low Carbon team has the expertise to make it happen. We work directly with architects, self-builders, and installers to provide bespoke Unico system designs. We will calculate the exact airflow requirements for each room, supply a detailed duct layout, and ensure the system integrates flawlessly with your primary heat source, such as a Daikin heat pump. We provide the technical heavy lifting so you can focus on the aesthetics.
