Ceiling Fan With Lighting - You know what? The title of this informative article is simply out and out misleading. The only real "con" when it comes to your ceiling fan is what it takes to get one correctly installed. Ceiling fans could be hard to install for the inexperienced do it yourselfer. Sometimes, where the ceiling fan is to be set up you'll need to run an electrical line to the place. Hiring a capable, bonded and licensed electrician will more than likely save you a lot of grief in the long term unless you are adept at doing this kind of thing.
There is also the minor "disadvantage" that entails the problem of regular maintenance. Correctly installed, a ceiling fan will give you many, many years of pleasant cooling and cost-savings in your heat bill (assuming you have a fan that allows you to reverse the blade direction).
On occasion, ceiling fans need small alterations and get out of balance. The most typical culprits are loose screws that attach the blades to the motor casing, blades that are not at precisely the same angle (pitch) as the rest of the blades and a blade or blades that weigh slightly more than the others. Make sure 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. In the event the wobbling has quit, your problem was solved.
If not, use a yardstick or other straight bit of wood and place it (together with the fan stopped) vertically at the outer edge of among the blades. Rotate the blades by hand to be certain that the stick is touched by every blade. If one or more do not, simply (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. Turn the fan on again and see if you've solved the problem.
