Ceiling Fan Led Light Dimmer Switch - You know what? The name of this article is just out and out misleading. The only actual "con" as it pertains to a ceiling fan is what it takes to get one properly installed. Ceiling fans might be difficult to install for the inexperienced do-it-yourselfer. Sometimes, where the ceiling fan will be set up you'll need to run an electrical line to the area. Unless you're skillful at doing this kind of thing, hiring a licensed, bonded and competent electrician will most likely save you much grief in the long run.
There is also the minor "con" that involves the issue of regular care. Properly installed, a ceiling fan provides years and years of nice cooling and cost-savings in your heat bill (assuming there is a fan which allows you to reverse the blade direction). Granted, you have to wipe down the blades in a while but then, everyone has household cleaning chores to take care of from time to time.
On occasion, ceiling fans require small adjustments and get out of balance. Be sure that every one of the screws are tight, without going into great detail. When they truly aren't tightening the ones that run the fan and have come loose. Your issue has been solved in the event the wobbling has stopped.
If not, utilize a yardstick or another straight bit of wood and place it (with the fan stopped) vertically at the outer edge of one of the blades. Rotate the blades by hand to be certain that the stick is touched by each blade. If one or more don't, merely (and gradually) bend the blade(s) so that their pitch matches the others and repeat the procedure until you're satisfied that each blade has the same pitch. Turn the fan on again and see if you have solved the issue.
