Let me give a better description of what I did...

Yes it is a window unit ( http://www.lowes.com/lowes/lkn?actio...XC5&lpage=none ).

I bent flexible metal wire into the rectangular shape of the AC vent. I then grabbed the dryer hose initially installed inside the cabinet, punched 8 small holes around the rim, and then bent wire between them to make a cage shape. Then I wrapped it with saran wrap to get the shape better then with clear packaging tape to make it sturdy. The cage is secured to the AC with tape on 2 of the 4 sides (incase pressure needs to escape). The other end of the hose is duct taped to the cabinet, temporarily unless I get lazy. Condensation builds up inside the "cage" and the hose gets cold and wet.

The closet is cracked opened 1-2" and the heat is being vented into the regular room. If I put my leg next to the crack I can feel the nice heat coming out. The regular room has only one large window where I installed a 20" box fan venting out that sucks harder than a Tijuana hooker.

Conclusion:

Window box fan med power
Cabinet temp: 65
Cabinet humidity: 60%
