This is perhaps the ONLY vertical window air con on the market since most other manufacturers discontinued them. If you have horizontally sliding windows and would like the energy efficiency of a window air con, this is a great option if you can't get a split installed.
These are far, FAR more energy efficient than portable units.
The price premium isn't too bad for the form factor at $499.
Marketing clowns, this unit is definitely not suitable for a room this size.
