If you have a small area to cool in the summer-say, one or two rooms a room air conditioner may be a more economical choice than a central air conditioning unit. It will cost less initially and it will cost less to operate in the long run.
Most room air conditioners sit in a window where they can exhaust warm air to the outside. Window installations can be drafty, however, so at the end of the warm weather season some people remove the unit from the window and store it for the winter. Room air conditioners can also be built into the wall for a more permanent installation.
Top name brands such as LG Electronics, Friedrich, Amana, Frigidaire and more will give you the comfort you need this summer.
