venting outside would be prime but not everyone can do that without worrying about LEO. You can vent to a seperate room or out a window or anywhere you pretty much want to to get the heat anywhere but inside your room. A portable ac unit also has heat that has to be vented but just heat, no poisonous gas or anything. If you are stuck in the 80's just be sure that air is moving as much as possible. Where are you currently intaking and exhaust from/to??
