What is the Unico System?

The Unico System is a type of HVAC system that uses small, flexible ducts to deliver conditioned air at high velocity. It’s ideal for installations where traditional ductwork is difficult — such as period homes, listed buildings, or properties with limited ceiling and wall space. It can be used for cooling, heating, or both, and it can be paired with heat pumps or other HVAC equipment.

Key Benefits of the Unico System

  • Discreet Design: Uses small outlets and hidden ducts that blend seamlessly into ceilings, floors, or walls — perfect for preserving the aesthetic of older or architecturally sensitive buildings.
  • Even Temperature Control: High-velocity airflow helps eliminate hot or cold spots for more consistent comfort.
  • Quiet Operation: Designed with sound-deadening insulation to operate quietly.
  • Flexible Installation: The small ducts can fit through tight spaces — no need to box in or build bulkheads.
  • Compatible with Heat Pumps: Works well with modern air-to-air or air-to-water heat pump systems.

While more common in the US, the Unico System has gained popularity in the UK for retrofits and high-end properties, especially where aesthetics or historic preservation are important. It’s often installed in townhouses, country homes, and heritage properties.
