How low of an air exit temperature can I get with the unit?

The air exit temperature can go down to 64 degrees in "room cool" mode and 32 degrees in "spot cool" mode. Please note that this unit will not cool an entire room to the temperature set in "spot cool" mode, and prolonged use of this feature could cause damage to the unit. Please refer to the manual for proper usage guidelines. If you have any further questions, please feel free to give us a call. Thanks!
