My ac suddenly clunked out last night. I turned it off, and left it off all night just in case the pipes were frozen. Got up this morning, tried it and it still wasn't working. I hear it pushing air, but there's no air coming through. The way my set up is, I have a furnace unit, and a outside fan unit. The fan is spinning, but there's no air coming throufh vent.

Just to clarify, the outside fan is spinning? Is the indoor blower working?
