We installed in our Master Bedroom and this is a super quiet 12,200 BTU A/C, it cools off our bedroom, master bathroom and closet beautifully. We love how the “inverted U” design drapes over the window sill, we’re confident it won’t fall out our second story window. The only trouble we had was connecting it to WiFi but that was quickly resolved by googling a YouTube video where the guy said to repeatedly tap the wifi button, don’t push it. GE should release updated instructions. Other than this snafu we love the unit.
