Cowboy Style Ceiling Fans - You know what? The title of the informative article is only out and out misleading. The only actual "con" in regards to your ceiling fan is what it requires to get one correctly installed. Ceiling fans can be hard to install for the inexperienced do-it-yourselfer. Sometimes, where the ceiling fan will be to be set up you'll need to run an electric line to the area. Unless you are adept at achieving this sort of thing, hiring a qualified, bonded and licensed electrician will more than likely save you much grief in the long run.
There is also the minor "minus" that involves the problem of periodic care. Correctly installed, a ceiling fan will give you years and years of nice cooling and cost-savings in your heat bill (assuming there is a fan that allows one to reverse the blade direction). Granted, you have to wipe down the blades once in a while but everyone has household cleaning chores to take care of from time to time.
On occasion, ceiling fans get out of balance and need small alterations. The most frequent culprits are loose screws that attach the blades to the motor housing, blades which aren't at the same angle (pitch) as the rest of the blades as well as a blade or blades that weigh somewhat more in relation to the others. Without going into great detail, make certain that all the screws are tight. When they aren't tightening the ones that run the fan and have come loose. Your issue was solved, in the event the wobbling has stopped.
Otherwise, make use of a yardstick or other straight piece of wood and put it (together with the fan quit) vertically in the outer edge of one of the blades. Rotate the blades by hand to ensure that the stick is touched by each blade. If one or more do not, just (and gently) 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. Turn the fan on again and see if you've solved the problem.
