Our Verdict

GE AHEF06BC

Toshiba RAC-WK0512CMRU

The GE AHEF06BC and Toshiba RAC-WK0512CMRU each have their strengths. The Toshiba is the better option for smaller rooms. Thanks to its shorter, more frequent compressor cycling, it does a much better job of maintaining the desired temperature and perceived ambient temperature levels. That said, the GE offers slightly greater cooling capacity and will chill the air in most rooms a little faster. It also provides a slightly more upmarket user experience, with a digital control scheme that allows you to input your desired temperature with more finesse, not to mention an included remote control.
