I bought this unit because I couldn't afford to get my central unit coil replaced it was just too expensive.  I put the unit in my living room area 800 sq ft. and you can feel that air blowing  7 feet away on the Couch. it is remarkably cool in this area that includes my kitchen and dining room.  I can't say enough about this unit, it's wonderful.  Will buy another one for my bedroom as soon as I can .
