For many years, homes and buildings built before the advent of central heating and cooling had to settle for the addition of inefficient window units and/or extensive demolition and remodeling to graft a conventional sheet metal ducted system to the structure; both approaches required a sacrifice of the structure’s original beauty. The Unico System is the complete solution to this problem, allowing the inclusion of a high-end air conditioning and heating system that can fit into the smallest of spaces, no matter what the architectural layout. The Unico System’s ability to blend into any décor renders it virtually invisible, further eliminating the unattractive appearance that is experienced with a conventional HVAC system.
