Why We Chose This Product:

The Midea 10,000 BTU U-Shaped unit earns top ranking by solving the two biggest complaints about window ACs: noise and blocked window access. Its U-shaped chassis isolates the compressor outside the window pane, bringing indoor sound down to 32 dBA while allowing full use of the window glass.
