A Quad-Zone system is designed to provide climate control for four distinct areas using only one outdoor unit. You can explore various configurations in our Quad-Zone collection. These systems are perfect for multi-story homes or large ranch-style layouts. For example, a Bravo Milano Series 4 Zone 36,000 BTU setup can handle four bedrooms with ease. Each zone can be set to a different temperature based on user preference. This reduces energy waste by only cooling or heating occupied rooms.
