Rustic Moose Ceiling Fan - Do you know what? The name of the informative article is only out-and-out misleading. The sole real "con" as it pertains to your ceiling fan is what it takes to get one correctly installed. Ceiling fans could be difficult to install for the inexperienced do it yourselfer. In some cases, where the ceiling fan will be installed, you'll need to run an electric line to the region. Unless you are adept at doing this type of thing, hiring a capable, bonded and licensed electrician will most likely save you a lot of grief in the future.
There is also the minor "con" that entails the problem of periodic maintenance. Correctly installed, a ceiling fan will provide years and years of nice cooling and cost-savings on your heating bill (assuming you've got a fan which allows you to reverse the blade direction). Allowed, you need to wipe down the blades in a while but then, everyone has household cleaning chores to take good care of of from time to time.
On occasion, ceiling fans require minor alterations and get out of balance. Without going into great detail, ensure that all the screws are tight. Whenever they aren't tightening the ones that run the fan and have come loose. Your issue has been solved in the event the wobbling has ceased.
Otherwise, use a yardstick or another straight piece of wood and place 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 every blade. If one or more don't, merely (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 issue.
