Question Ceiling fan mounting

I am putting a ceiling fan into an existing ceiling. What type of mounting system do I need and how would it work? A traditional electrical box doesn't seem like it would provide enough support.

You're right about that. A regular electrical box will NOT support a ceiling fan, at least not very long. You need a pancake box. These are about 1/2" deep, but they will only work if they can be mounted to a joist. If not, you can get a support at Home Depot that will work. It's about $15 with a box and everything. Do NOT install a ceiling fan without bracing it some way, whether to a joist with a pancake box, or with the fan brace from HD. Not if you want a good nights sleep anyway

You need a fan-rated box. In addition to being a metal box, it has longer female threads (a regular box has less than 1/16" of female threads). Finally, you will need to make sure this is attached directly to framing. This can be done in any number of ways, including the two ways that SafeWatch has mentioned. If you can get above this room into the attic, you can also add 2x4 blocking between the joists.

I prefer the 2X4 method... been doing it for 6 years...and didn't have any fans fall down yet.
