We purchased 2 of these air conditioners in different sizes. One was defective right out of the box. GE deemed it not repairable, & we received a replacement 3 weeks ago. Meanwhile, the larger unit started making a horrible noise (I have a video but am not sure it will upload to this review) on “cool” setting. On “quiet”, it rumbles so much we can feel the vibration on both couches in the room. Last night, the 3-week old replacement unit also started to rumble. It woke me up at 3a.m., and I had to turn it off to be able to sleep. We were excited about the design of these, but I’m starting to hate them.
