Thanks to Karl and Gabi, they went with me today on my quest to locate a new A/C. We went to 3 stores before I settled on a free standing unit. It comes with a hose that fits into a panel that actually works in my sliding window in my bedroom. I finally have an A/C unit in my room. Previously the A/C unit I was using sat in the window in the hallway, I then had a set of fans I used to “pipe” air into my room. This will be MUCH more efficient, and best of all, to remove it from my window takes all of 2 minutes time, tops and it requires NO modification of the window.
