Thanks. I was thinking of shutting the vents of one room in the house that is empty and unused, but I figured just keeping the door closed would probably be better, right?

Shut it off, it won't hurt anything. It's only an issue if you're shutting off a lot of vents. Now how much good it'll do energy saving wise, depends on where the room is in the house and how old your house is. Newer houses with better insulation will see much less improvement.

Won't it potentially cause humidity issues? The room does not get direct sunlight (faces south). It's a new house with pretty good insulation (as far as I've experienced so far).

Without being there, I couldn't say for sure., but I doubt it Personally, I would just use common sense. Shut it off and and just check the room a couple times over the next week or two.

I agree that shutting 1 vent isn’t going to kill your system. However, that one room isn’t insulated on interior walls. Best to leave it alone for overall comfort. You aren’t saving $ closing the vent. The system is going to run until the thermostat is satisfied no matter what.

Also, best thing for the entire building is to run the fan constantly (I forgot to mention this in the original). Balances the building much better than just the entire system kicking on and off every 15 min or so.
