I put the unit in my garage window. I have an 8x10 office/podcast studio. Quiet is important. This thing is quiet. The only noise it made was when water built up inside from condensation. I pulled the drain plug and that was that. NO NOISE. It cools the room down without any trouble. I got the app and set the auto on/off throughout an 8 hour day. This was a huge investment for me and I am not disappointed. Podcast - Neighborly Discourse
