Our Verdict
Frigidaire FFRA051WAE
Toshiba RAC-WK0512CMRU
The Toshiba RAC-WK0512CMRU and the Frigidaire FFRA051WAE are very similarly designed entry-level window A/Cs. Despite the Frigidaire's on-paper advantage in advertised coverage, both units deliver all but identical cooling performance. The Toshiba operates a little more quietly while experiencing fractionally lower swings in ambient humidity once it's reached your desired temperature.
