Hunter Sonic Ceiling Fan With Light - Do you know what? The title of this article is only out-and-out misleading. The only real "con" in regards to some ceiling fan is what it requires to get one correctly installed. Ceiling fans can be difficult to install for the inexperienced do-it-yourselfer. In some instances, you will need to run an electric line to the location where the ceiling fan is to be installed. Hiring a qualified, bonded and licensed electrician will probably save you much grief in the long term, unless you are skillful at achieving this sort of thing.
There is also the minor "con" that involves the problem of regular maintenance. Correctly installed, a ceiling fan will provide many, many years of nice cooling and cost-savings on your own heating bill (assuming you've got a fan that allows one to reverse the blade direction). Granted, you have to wipe down the blades once in a while but then, everyone has household cleaning chores to take care of from time to time.
On occasion, ceiling fans get out of balance and require small adjustments. The most common culprits are loose screws that attach the blades to the motor casing, blades that aren't at exactly the same angle (pitch) as the remaining blades and a blade or blades that weigh somewhat more in relation to the others. Without going into great detail, ensure that every one of the screws are tight. If they're not tightening the ones that run the fan and have come loose. Your problem has been solved in the event the wobbling has ceased.
If not, utilize a yardstick or another straight bit of wood and put it (together with the fan quit) vertically in the outer edge of among the blades. Rotate the blades by hand to make sure that the stick touches. If one or more don't, just (and gradually) bend the blade(s) so that their pitch matches the others and repeat the procedure until you are satisfied that each blade has the same pitch.
