I bought my portable air conditioner a month age.  It's wonderful!  My mom's house has central air, but the upstairs is really warm.  I didn't want a window air conditioner because I was afraid of damaging the new windows.  Portable is the way to go. The hose is an inconvenience, but I can live with it.  The noise level is good. The room I am cooling is bigger than recommended and it works just fine.  Buy this air conditioner.  You won't be sorry.  Love it.
