Portable A/C
 

My room gets extremely hot so i bought a portable a/c unit. Only problem is that using the window exhaust isn't possible. Would i be able to maybe use something like a dryer vent type of exhaust. The tubing that came with the unit is 5 inches wide while all dryer vents are 4 inches wide. Any suggestions is greatly appreciated. Thanks.

u get it a figured out i hope
