Central AC makes a racket. If you've ever spent time in a home with conventional cooling, you know it's always easy to tell, simply by listening, whether the system is on or off. If, like most people, you prefer your home environment to be a refuge of peace and quiet, the noise of a traditional setup can be a constant, inescapable nuisance. Here's the good news: Nowadays, not all central air-conditioning systems are noisy. For instance, the Unico System, from its air handler to its innovative ducts, comes equipped with an array of sound-deadening components and design features to ensure whisper-quiet performance. In short, you cannot hear Unico at work, but you can certainly feel it!
