Western Ceiling Fans With Stars - You know what? The name of the informative article is merely out-and-out misleading. The only actual "con" as it pertains to a ceiling fan is what it will take to get one correctly installed. Ceiling fans could be hard to install for the inexperienced do-it-yourselfer. In some instances, where the ceiling fan would be to be installed, you'll need to run an electric line to the location. Unless you are skillful at achieving this sort of thing, hiring a capable, bonded and licensed electrician will probably save you a lot of grief in the long term.
There's also the minor "minus" that involves the issue of periodic maintenance. Properly installed, a ceiling fan will give you years and years of agreeable cooling and cost-savings on your own heating bill (assuming you've got a fan that allows one to reverse the blade direction). Granted, you have 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 get out of balance and require small alterations. The most common offenders are loose screws that attach the blades to the motor housing, blades which are not at precisely the same angle (pitch) as the remaining blades and a blade or blades that weigh somewhat more than the others. Ensure that all the screws are tight, without going into great detail. When they're not tightening the ones that run the fan and have come loose. If the wobbling has ceased, your problem was solved.
If not, use a yardstick or another straight piece of wood and put it (with the fan stopped) vertically at the outer edge of among the blades. Rotate the blades by hand to ensure that every blade touches the stick. Turn the fan on again and see in the event you've solved the issue.
