Our scoreSCORE6.4 / 10SCORE7.2 / 10
Our takeThe Duo we'd get for a typical bedroom: 10,000 BTU SACC, inverter, Midea-rated up to 450 sq ft. If your window takes a 10,000 BTU Midea U, that's the better buy at the same rating.The size step for a living room up to 450 sq ft, in the lighter 62 lb top-down chassis with the same 22-36 in window fit as the 6,000. Its 50 dBA low fan step makes it a poor fit for a small bedroom.
