My husband is a musician who needs solitude and space to create.  He uses our 3rd floor finished attic as his studio.  Our older home has no duct work to this area, so central air does nothing for him.  What a fantastic find is this Black and Decker 14,000 BTU portable air conditioner! My  creative genius now feels secure with his "babies" (musical equipment) all nice and comfy and cool without the danger of overheating!  This system is quiet (which is mandatory for a musician in deep thought and fine-tuning a composition.) He/We are completely overjoyed with this easy to install, efficient system.  Everything we needed to get things up and operating was in the box.  Hubby is very picky and quite handy.  When winter comes, all we have to do is take the exhaust out of the window, slide the unit to the side, and wait until warm weather returns to use it again.  This system gets rave reviews from us!  P.S.  The remote control is a joyful added perk!
