Beacon Lighting Futura Ceiling Fan - Guess what? The name of the article is just out-and-out misleading. The sole real "minus" in regards to a ceiling fan is what it requires to get one properly installed. Ceiling fans can be hard to install for the inexperienced do it yourselfer. In some instances, where the ceiling fan will be installed, you will need to run an electric line to the place. Unless you're skillful at doing this type of thing, hiring a capable, bonded and licensed electrician will more than likely save you a lot of grief in the long run.
There is also the minor "minus" that entails the problem of regular care. Properly installed, a ceiling fan will provide years and years of pleasant cooling and cost-savings in your heating bill (assuming you've got a fan that allows one to reverse the blade direction).
On occasion, ceiling fans get out of equilibrium and need small alterations. Make sure that all of the screws are tight, without going into great detail. If they aren't tightening the ones that run the fan and have come loose. Your issue continues to be solved when the wobbling has stopped.
If not, use a yardstick or other straight piece of wood and place it (together with the fan quit) vertically at the outer edge of one of the blades. Rotate the blades by hand to be certain that the stick touches. Turn the fan on again and see if you've solved the issue.
