After suffering without an air conditioner through too many humid, sleepless New England summer nights over the 21 years we've lived in our historic (1739/1820) home in Massachusetts, we decided it was time for the suffering to end! Our challenge: cooling our bedroom without a conventional, clunky air conditioner protruding from our bedroom window. The perfect solution: the LG  Electronics LP0721WSR. Not only does it cool the room quickly and efficiently -- with a range of temperature and functional options --  it's virtually invisible from the outside and it has allowed us to enjoy a comfortable night's sleep even on the most humid summer nights.
