I bought this a couple of weeks ago to chill the master bedroom without having to bring the whole house down to 65 degrees using the 4 ton unit on the main level.  It does a great job and with the Thin Q App I can set the timer to come on each evening before bedtime so the room is nice and cool before sleeptime.  It is so quiet that I cannot discern when the compressor cycles on and off.  I can heartily recommend this unit to anyone seeking to accomplish the same.
