The LG Art Cool Mirror is a residential and light commercial system that uses a variable speed compressor that is energy efficient and quieter to operate than conventional air conditioning units, the company says. These duct-free systems feature sleek, charcoal mirror-finished indoor units, and outdoor units with energy-efficient inverter technology. The outdoor unit supports cooling operations down to the standard 14 degrees Fahrenheit and heating operations down to -4 degrees Fahrenheit. There is also a defrost feature, which removes frost from the condenser coil in frigid conditions. The system comes in a single- or multi-zone solution.
What the judges say: “Again, someone made an air conditioning unit look better? It's the attention to design detail and functionality that I appreciate so much. This one is slick.”
