I chose a portable over a window mount for a couple reasons... the homeowner covenants where I live don't allow window mounted units, and it's going to be doing double duty: keeping my garage cool in the day when I'm detailing, and keeping our west facing master bedroom cool at night. I got the more expensive one with the remote.
No more sweltering heat this detailing season!
