Stained Glass Ceiling Fan Light Shades - You know what? The name of the article is just out and out misleading. The only real "con" in regards to your ceiling fan is what it requires to get one properly installed. Ceiling fans may be hard to install for the inexperienced do it yourselfer. In some cases, where the ceiling fan is to be set up, you will need to run an electric line to the place. Unless you're skillful at doing this type of thing, hiring a capable, bonded and licensed electrician will most likely save you a lot of grief in the long term.
There's also the minor "minus" that entails the issue of periodic maintenance. Correctly installed, a ceiling fan will give you many, many years of enjoyable cooling and cost-savings on your heat bill (assuming you have a fan that enables you to reverse the blade direction). Granted, you should wipe the blades down once in a while but then, everyone has household cleaning chores to take good care of of from time to time.
On occasion, ceiling fans get out of balance and need slight adjustments. The most typical culprits are loose screws that attach the blades to the motor housing, blades which are not at exactly the same angle (pitch) as the remaining blades and a blade or blades that weigh slightly more than the others. Without going into great detail, make certain that all of the screws are tight. If they truly aren't tightening the ones that have come loose and run the fan. Your problem has been solved, in the event the wobbling has stopped.
Otherwise, make use of a yardstick or another straight bit of wood and place it (together with the fan quit) vertically at the outer edge of among the blades. Rotate the blades by hand to make sure that each blade touches the stick.
