    I have a window in my bedroom it only measures 14.5 inches wide. I have been searching like crazy but cannot find an air conditioner that is that small. Do you know if they make any with this width?

  2. Lou Viggiano

    Is there any way one can set up one of these small a/c’s to cool down a tent in a campground? Even if I need to build a mini space outside the tent to house the body of the unit.

    1. M. Risner

      Hello, you would just need something to set the air conditioner on and a hole in the side of your tent. I would think a small sturdy metal table would work. Good luck!

      I took one camping and zipped the door around unit. Sat on the ground with a 2×4 under front and a 1×4 under back for drainage. Worked like a charm . Froze my kids,lol.
