Ceiling Fan Safety Cage - Do you know what? The name of the informative article is simply out-and-out misleading. The only actual "disadvantage" as it pertains 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 cases, you'll need to run an electric line to the area where the ceiling fan is to be set up. Hiring a capable, bonded and licensed electrician will probably save you a lot of grief in the future unless you're skillful at achieving this type of thing.
There is also the minor "disadvantage" that involves the issue of periodic care. Properly installed, a ceiling fan provides years and years of agreeable cooling and cost-savings on your heat bill (assuming there is a fan which allows one to reverse the blade direction). Granted, you need to 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 minor alterations. Make sure that all the screws are tight without going into great detail. Whenever they truly aren't tightening the ones that run the fan and have come loose. When the wobbling has ceased, your problem has been solved.
If not, use a yardstick or other straight bit of wood and put it (with the fan stopped) vertically at the outer edge of one of the blades. Rotate the blades by hand to ensure that every blade touches the stick.
