I bought this unit for my daughters house in Washington DC . The window that I needed to install it in is not very wide and left me no choice but to purchase a narrow style unit . It was very easy to adapt and install in a double hung window . I chose Frigidaire for its great reviews . Turned unit on and I was amazed how quiet the fan sounded on high speed . The discharge airflow into the room from this unit truly impressed me . I didn’t even hear the compressor come on when in cooling mode . This unit exceeded my expectations. Compact design , I’m amazed that it works so well . Very pleased , and my daughter and son in law love it .
