If that install will meet your need it's definitely the way to go. I'm now curious about the cost to install a traditional through-the-wall air conditioner. Let's assume it's a $600, 12,000 BTU unit (which we'd probably need a few of). The Btu size of the unit or the state it's done in really don't affect the work involved. No one CAN know. At my BRICK house it would be a much bigger job than at my son's frame house. Either way... the units will need to have power run to each of them which opens a whole other Pandora's box of possible issues.I was simply poking fun at the fact that he completely ignored the question being asked. I'm just looking for ballpark figures here, and/or other people's experiences. Even for ballpark YOU need to provide far more information than you have. I didn't "ignore" the question.
