The Bravo Milano Series 4 Zone 36,000 BTU (9k x 4) is ideal for equalizing comfort in four smaller rooms. You can find this configuration in our Quad-Zone collection. It’s an excellent way to handle multiple guest rooms or office cubicles. By using smaller 9k units, you avoid over-cooling any single space. This system is a highlight of our Multi-Zone offerings. It provides a comprehensive and balanced approach to whole-home cooling.
