I bought this about a month ago and had my brother install it for me.  He stated that it was super easy to install. He only needed help lifting it to fit into the sleeve since it is heavy.  It keeps my place cooler than I thought a windiw unit would. As a added feature it is WiFi connected making it easy to make sure it stays cool for my two dogs while I am working.  It doesn’t run constanty, only when needed saving electricity. So glad I purchased this unit.
