Woke up one morning to hearing a loud vibration... turned off ac. Had to take the unit out of the window to check to see what it was and where it sucks the air my dad and I noticed that there was a piece of the fan missing. Not sure how this would happen consider we bought it in May of 2022. So not even two months, hoping to be able to get the unit replaced under warranty. Other then that the ac was amazing before this mishap. App and wifi was great.
