My neighbor has an old Fridigaire window unit he uses to cool his garage. He said he moved it out there when they got central air about 30 years ago, and they've had it for at least 50 years or so. It's a neat looking old unit. I didn't even know GM built window units under the Fridigaire nameplate. I'll hafta take some pictures of it tomorrow and post them. I imagine the unit is terribly inefficient, but it sure gets his workshop cooled down in a hurry! The label on the side says it's an R12 unit too!
