My husband and I purchased this unit for our detached garage.  In addition, we had spray foam insulation added to the garage.  This combination has worked very well in not only keeping our garage cool, but also keeping the air dry.  The unit does a great job of removing humidity from the air.  As with several other reviews that we have read, one of the outside lower corners was bent when we received it.  We decided to not return it, but were really disappointed especially since the unit costs considerably more than the typical window unit.  We think that packaging is an area that Frigidaire could make some improvements on.
