We have an open floor plan with our kitchen, living room and dining area and this air conditioner does a decent job of keeping the whole area cool on its own. Its only fault is that is that it has disconnected from the Wi-Fi a few times already, which is a pain when you want to turn it on from the app on your phone. But it hasn't been too hard to reconnect. We liked it so much we purchased a smaller Frigidaire model for our bedroom!
