I bought this for my home office primarily because it was supposed to be the quietest window a/c unit available, and it certainly is.  I was worried that I would have to turn it off during zoom meetings but you hardly notice it. This unit was real easy to install, doesn't obstruct the window view like the old window units used to, and is sooo quiet.  I have it on a schedule through the android app and it works very well.  Very easy to use.  A little pricey but you get what you pay for, usually! Highly recommended to others.
