Can I extend the exhaust hose for my portable air conditioner?

Unfortunately, No.  The exhaust hose that came with your portable air conditioner has been specifically designed for use with that particular unit.  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.  

The exhaust hose packaged with your portable air conditioner may be stretched to its maximum length (approximately 48 inches) however for maximum efficiency the hose to should be set to the shortest length possible keeping in mind to avoid kinks or bends in the hose.  

You can also vent through the ceiling using a Drop Ceiling Kit or out a sliding glass door with this conversion kit
