It’s impossible to ignore the operation of conventional heating, being that such systems announce themselves with a roar. The noise continues for a period of time, suddenly grinds to a halt, then returns some minutes later, drawing your attention once more. The cycle repeats, over and over, all winter long. In contrast, the Unico System provides whisper-quiet climate control by gently distributing conditioned air through mini supply ducts, each ringed in dual-layer, sound-dampening insulation. The air handler runs quietly too, thanks to the closed-cell foam designed to hush its internal components. So in addition to total comfort, you also get to enjoy the sound of silence.
