I read somewhere that excess smoke can be caused by the actual fireplace being too big for the flue. I guess my question is, how can you tell if it is a normal amount of smoke or another issue that will require professional help?

You are corect this can be an issue. Smoke chambers and smoke shelves are often put in to compensate for this draw issue. If you have a larege fireplace that is more than 55" across and the chimney flue is 25% that size or less then it could be too small of a flue that would need to be compensated by a chimney fan like an Exhausto.

I am not a big proponent of this measure though since a chimney fan just accelerates the air loss and makes the fireplace operate at negative efficiency.

Unfortunatly with open firepalces you are going to pay a real price to use them. It is just a matter of how much you are willing to waste or spend.
