The Unico System

Small-duct high-velocity comfort that fits homes where conventional ducts won't.

The Unico System is the only central heating and cooling system endorsed by the National Trust for Historic Preservation — and a favorite for the mid-century modern and radiant-slab Bay Area homes where standard ductwork would ruin the architecture. Air Synergy is a Unico Preferred Contractor.

About The Unico System

Unico's small-duct high-velocity system uses 2-inch flexible ductwork that snakes through walls, ceilings, and joist bays without the massive chases traditional ducts need. Air is delivered through small round outlets that all but disappear into the room. Ideal for historic homes, mid-century moderns with flat roofs, radiant-slab homes without existing ducts, and anywhere a conventional duct retrofit would be architecturally destructive.
