Anyways, years later we had a A/C unit installed and connected to the furnace. We still hadn't really used the air exchanger up to this point. I recently turned on the air exchanger while my furnace thermostat was set to off just to circulate the air in my house. I noticed that the fan on my A/C unit would run when the air exchanger was on. It was not cooling the air but it was running continuously while the air exchanger was on. Is this normal? I don't know much about these things.

Yes if you are running the air exchanger the furnace fan will come to replace the air in the house that the exchanger is removing from the house. Air going out has to be replaced with air from your furnace it will have a fresh air outside connection that pulls in the fresh air to accomplish this. This is a typical hook up in the newer homes.
