The length of the exhaust hose cannot be increased. Longer exhaust hoses interfere with proper unit operation and can result in unit failure. Lengthening, modifying or using a longer hose can cause the unit to operate inefficiently and will reduce the cooling effectiveness of your portable air conditioner.
Note that the unit clearance required for these units to operate efficiency is listed typically at 20" (from nearest wall or obstructions). Please refer to the user manual for your product for additional information.
