I bought this portable A/c unit for our office room, which we spend a great time of our day.  This room is on the west side of the house and the furthest from the central air unit.  Therefore, the afternoon Phoenix heat will heat this room as much as 10 degrees over the rest of the house.  This unit does the job.....nicely.  The fact that it is wifi compatable with the Google Home System was a real plus.....I completely operate the unit via the LG-ThinQ app and Google voice commands.  I'm very happy that I purchased this LG portable A/c unit.
