What a beast AC for my office! I have 3 PCs and network rack which has 2 NAS and bunch of network equipments in my office, so the temperature usually as high as 90-95 during summer time. This unit is able to cool down the temp to 75F within 3mins! Amazing, only one thing the noise level is a little high when the fan is on medium or high. But other than this this is an excellent AC unit.
