This window air conditioner works great! It cools our large bedroom well. I really like that it has a low profile so it does not block the whole window. The Smart HQ app is a really neat feature. It allows you to turn the air conditioner on and off as well as control the temperature from your phone. It also let's you set a schedule and see the filter status. Initially I had difficulty connecting the air conditioner to the Smart HQ app. Customer service was very helpful and was able to walk me through how to connect to it in simple terms. This only took a few minutes. I would highly recommend this air conditioner for its ease of use and also for GE's customer service.
