We were searching for some new window ac units that were quiet, small enough to fit our new windows and attractive. While doing a lot of research, I saw windmill mentioned in several reviews online from reputable sources and so decided to look into them. I was having a lot of trouble finding nice looking 10K btu units that would fit our windows (in fact, I had to give away our only 2yo LG unit bc it didn’t fit the windows in our new apt) and was very pleasantly surprised that the 10j Windmill was small enough to fit! We decided to go with 2 smaller 6k btu units first in our smaller rooms to test out and were thrilled. They looked so much nicer than normal AC, we’re quiet and can be controlled on our phones. We then took the plunge with a 10k unit and couldn’t be happier with the results. It’s so quiet and our apt finally feels like it has central AC! Would 10/10 recommend.
