Since day 1 it makes this fluttery chattering scratchy noise on all modes. It is not a normal noise.There are other reviews that mention a scratchy noise.  After two or three weeks, the noise went away for a few days but has now returned. I was hoping to get it looked at through Frigidaire's authorized service but the COVID policy doesn't allow service calls at this time.
It's not as quiet as others have said. It cools pretty well, I guess. I am just really annoyed with the noise issue which is really disappointing.
I wish the display on the unit was larger or showed up on the remote. Really hard to see unless i get really close..
