Got this for my mother as her new apartment is very hot, and quite large.  I wanted something that would cool the whole place, and not be too noisy.  Reviews said it was quiet, and she confirmed that it is!  Only thing wrong was her windows are horizontal sliders, 62” long, so the installation panel in the kit wasn’t quite long enough.  The person who installed it just added an extra panel he made from something else to fit the gap, and she covered it with the blind, so all good!
