Harbor Breeze Dual Head Ceiling Fans - Do you know what? The name of the informative article is merely out and out misleading. The only real "disadvantage" as it pertains to some ceiling fan is what it will take to get one properly installed. Ceiling fans may be difficult to install for the inexperienced do-it-yourselfer. In some instances, you'll need to run an electric line to the region where the ceiling fan is to be installed. Hiring a competent, bonded and licensed electrician will more than likely save you a lot of grief in the long term, unless you're adept at doing this sort of thing.
There's also the minor "disadvantage" that entails the issue of regular maintenance. Correctly installed, a ceiling fan provides many, many years of nice cooling and cost-savings on your own heating bill (assuming you've got a fan that allows you to reverse the blade direction). Granted, you need to wipe down the blades once in a while but then, everyone has household cleaning chores to take care of from time to time.
On occasion, ceiling fans get out of equilibrium and require small alterations. Without going into great detail, make certain that all of the screws are tight. Whenever they aren't tightening the ones that run the fan and have come loose. Your problem was solved in the event the wobbling has stopped.
If not, utilize a yardstick or other straight bit of wood and place it (together with the fan stopped) vertically in the outer edge of one of the blades. Rotate the blades by hand to make sure that the stick is touched by every blade. Turn the fan on again and see in the event you have solved the issue.
