TOM KRAEUTLER: Hey, it’s Tom Kraeutler and this is the Money Pit’s Top Products podcast, broadcasting to you direct from San Francisco. We are at the Moscone Center, which is the center of Greenbuild 2012. And now we are going to talk a little bit about air conditioning technology. You know, a cool, comfortable home or office is important. If you don’t have central AC, though, you could be struggling with window or portable units to try to keep your cool.
