I noticed signs of previous condensation on the underside of a front porch ceiling in this new construction house in Cumming. This seemed unusual, so I got out my infrared camera. The thermal image shows a solid cold spot on the ceiling that corresponded to a finished area directly above this ceiling. And since the interior was cold from running the A/C, the cold air appeared to be spilling out above the exterior ceiling area where the condensation had formed. I suspected missing or poorly installed insulation and called it out for the builder to investigate.
