I bought 2 of these A/Cs, one at one end of the house and one at the other end. I have french doors that can be closed to either side and just run one if I don't want to cool the entire house. They are very efficient - they cool down the house in a hurry.

We just had our first heat wave of the year and our new LG performed perfectly. We are using it to cool two rooms totaling about 700 sq. ft. and it is more than adequate
