September 26, 2007 - Making their debut to the Ice Qube top mount line are the IQ2000TXS and the IQ2500TXS. The A/C units will have the same width and depth dimensions as their predecessors--the IQ1800TS and the IQ2300TS, which are no longer available--but are taller to make room for the new robust compressor to deliver more BTUH power.Ice Qube also added 3000 BTUH and 4000 BTUH models.
