In a 600sq. ft. room works great. I installed it through the wall and had to make some adjustments because the old one was a bit smaller. I initially had it set to 70, high fan, moved it to 72 high fan and by night time, 72 low fan. On low the noise...

Easy to operate. Like the digital controls. A little heavy requires 2 people to install, but simple. Cools great. Like the washable filter.
