I have a large room (20'x20')that is NOT ajoined by exterior walls, so, I can't simply stick an a/c through a wall (also central air is not a good option for me).

Someone told me of "mini-split" a/c units--- as described, mini-splits WILL work! HOWEVER, the same person who described mini-splits, also describe a less expensive way to go--- he described a "packaged outdoor a/c units" or a "trailer a/c package" where, with a little ductwork, I can get my problem solved, but with less expense than a mini-split. HERE'S THE PROBLEM: When I do a "Yahoo" search for "packaged outdoor air conditioning" or "trailer air conditioning package" or "mobile home air conditioning,"---- I am not finding what this person had describe. I do find lots of "mini-splits" --even portable a/c units--- but nothing as described. Perhaps, manufactures have another term for these units?? Can someone HELP with the correct name? --brand & model #s would be good! OR specific websites? ---Any HELP would be most helpful, as I am in the middle of remodeling this unit--- it would be nice to get one of these a/c units installed while everything is tore up. Thanks for any help. Jaes.
