Portable Air Conditioning Units for Cooling a House

Portable water cooled evaporative air conditionerI am hoping to figure out a way to cool my house that will not cost me a whole lot of money. It is the middle of summer, and the air conditioning unit in my house is broken, so I need to figure out a way to keep the house form getting unbearably hot during the heat of the summer. I am currently looking for some good information on portable air conditioning units, and I am also looking for portable air conditioner reviews in order to figure out what other people have to say about such products.

The central air in my house is broken due to a coolant leak in the system at some point.
