Acoustic dampening architecture involves the internal soundproofing of the indoor and outdoor units to ensure a peaceful living environment. Our Bravo Milano 12,000 BTU Universal Floor/Ceiling unit is built with vibration-absorbing materials to keep decibel levels at a minimum. For those installing a Penta-Zone system, maintaining a quiet exterior is essential for neighborly relations. We recommend checking our Other Accessories for specialized rubber pads that further isolate mechanical noise. Even our Wall Mounts (2 Zones) are tested to ensure the blower motor doesn't disrupt sleep. By focusing on the architecture of sound, we provide a luxury experience that goes beyond mere temperature control. Silent operation is a hallmark of the quality found across the entire Bravo Milano catalog.
