Replacing an existing light fixture with a ceiling fan is only slightly more cumbersome than installing a light fixture. While it is best to leave electrical projects to licensed electricians, do-it-yourselfers with electrical experience often install ceiling fans themselves. The tricky parts involve purchasing the right sized fan and lifting the sometimes heavy motor unit in place. If you have installed light fixtures, you can install a ceiling fan.
Ceiling fans are an unobtrusive and economical way to cool a room in summer and move heat back down to floor level in winter. For best air flow, locate a ceiling fan in the midpoint of the ceiling. If the existing light fixture is off center but close to center, it is easier to use its wiring than to install a new box and wiring.
