My house only has red and black wiring (old house). So I'm kinda lost on ceiling fan install. Is my red neutral? Do I connect white from fan to red from ceiling? Pig tail red from ceiling and switch with white from fan? I've spent a couple of hours rewording all this many different ways into Google and can find NO help. Yes I know red is supposed to carry power and white is neutral. But thats not the case in my situation?
