Toshiba RAC-WK0512CMRU vs RAC-WK0612CRRU

The Toshiba RAC-WK0612CRRU and Toshiba RAC-WK0512CMRU are both window-mounted ACs with slightly different capacities. The WK0612CRRU is the fractionally larger, pricier option with an advertised capacity of 6,000 BTU/hr, compared to the WK0512CMRU's 5,000 BTU/hr. This gap in capacity isn't sufficient to run the risk of cooling an equivalently sized room too quickly and causing a buildup of humidity. The WK0612CRRU's somewhat greater capacity also means its compressor cycles less rapidly, resulting in larger, more frequent swings in humidity and temperature. On the upside, the WK0612CRRU, unlike the WK0512CMRU, has a digital thermometer that lets you set the desired temperature and comes with a remote control to operate the unit from a distance.
