This 8,000 BTU window unit is one of the highest rated onand has 16,656 reviews on Amazon. It's designed to be far quieter than traditional air conditioners thanks to its unique U-shape and a high-efficiency inverter system that keeps running costs low and creates long distance airflow that can reach up to 20 feet.
Almost everything bad or inconvenient about in-window AC units is totally resolved by this product. It really is impressively quiet thanks to the 'split unit' design where the window is used to create a barrier between the compressor and front. Not only that but thanks to this design in conjunction with loads of provided insulating foam, it keeps the heat out, and in.
