not thread jacking just got one noobish question for natrone, i know how hot the air is that comes out of those ac's and my quesiton is that with it being exhausted into the attic will it not make the attic look extremely hot to a flir camera on a helicopter or is there no heat signature. i was thinking about using one but exhausting out a window is not an option and i was looking for some alternative ways while still being safe.
