I installed this a/c a few weeks ago and so far it’s been great! It’s only May so I haven’t yet tested it through the hottest parts of a NYC summer. However, we’ve already had some pretty hot days and my room tends to get very very warm as it gets direct sunlight for most of the day and is very small with little airflow. I was surprised at how quickly this a/c was able to cool down the space and am impressed with it’s efficiency- it really only turns on when it needs to. I also love the remote! It tells you the temp of the room and you can set the a/c to adjust based on the temp of the remote. I like to put the remote in the warmest corner of my room furthest away from the a/c so that it cools down the entire room before shutting off. My only complaints so far is that it beeps really loudly whenever you press one of the buttons, which seems unnecessary. Also, the a/c itself is a bit louder than I expected.
