Decorative Ceiling Fan Chain Pulls - Guess what? The title of this article is just out-and-out misleading. The sole real "con" in regards to some ceiling fan is what it will take to get one properly installed. Ceiling fans might be difficult to install for the inexperienced do-it-yourselfer. In some cases, you'll need to run an electric line to the place where the ceiling fan will be set up. Unless you are adept at achieving this type of thing, hiring a licensed, bonded and competent electrician will more than likely save you a lot of grief in the future.
There is also the minor "minus" that involves the problem of regular care. Correctly installed, a ceiling fan will give you many, many years of pleasant cooling and cost-savings on your heating bill (assuming you have a fan which allows you to reverse the blade direction).
On occasion, ceiling fans get out of equilibrium and require small alterations. The most frequent culprits are loose screws that attach the blades to the motor casing, blades that aren't at precisely the same angle (pitch) as the remaining blades and a blade or blades that weigh slightly more than the others. Make certain that all of the screws are tight without going into great detail. If they truly aren't tightening the ones that run the fan and have come loose. Your problem continues to be solved when the wobbling has stopped.
Otherwise, utilize a yardstick or other straight piece of wood and put it (together with the fan stopped) vertically in the outer edge of among the blades. Rotate the blades by hand to be certain that the stick touches. If one or more don't, only (and gradually) bend the blade(s) so that their pitch matches the others and repeat the process until you are satisfied that each blade has the same pitch.
