Hey, Its isn't the Freon that moves it is the compressor oil. When you turn it in a direction that it isn't supposed to go all of the oil drains out of the compressor. When you turn it on and there is no oil the compressor will fry, cook, burn, and die. I would look at getting a portable A/C. These are generally made to stand upright. You can put the unit under the house. You then simply put in a duct attached to a floor grill to bring the air to the A/C. Then you just duct the cool air in though a grill an another area. Ghetto central A/C.
By the way. I don't think that doing any of this is worth it.
