If you are looking to install a ceiling fan in your home, the first question you might have is whether or not you need a special ceiling or junction box to mount it. The answer to this question largely depends on the type of fan you purchase and the weight of the fan. Most ceiling fans come with all of the necessary hardware for installation, which should include an appropriate ceiling box. If your fan is particularly heavy, however, you may need to upgrade to a heavier-duty box. Check the manufacturer's instructions for more information. In some cases, you may be able to install your ceiling fan without having to do any electrical work at all. These so-called "plug and play" fans simply plug into an existing outlet and hang from the ceiling just like a light fixture.
