What size room will it cool?

Perfect Aire rates it for rooms up to about 150 square feet. That suits a bedroom, small office or den, not an open living area.

Does it need a window?

Yes. A portable air conditioner exhausts hot air through a hose, so it needs a window or sliding door to vent out of.

No. It is not ENERGY STAR certified, so it uses more electricity than a certified unit of similar cooling capacity.

The unit and a remote control. The venting kit for the window hose is part of the setup.

No. It is a cooling-only unit with three fan speeds, a timer and a display.

No. At 8,500 BTU it is meant to cool one room at a time, and a single-hose design struggles to cool several connected spaces.
