Main Que: In what situation is a PTAC a bad idea?

Answer: Attempting to cool and/or heat a multi-room residential or office space wouldn't be the most efficient usage. A single unit can cool two rooms if it is big enough and fans are used between rooms to move cool/warm air into the second room. Anything beyond that will stress the unit and leave some room occupants too hot or cold depending on the season.
