Large Great Room Ceiling Fans - You know what? The title of the informative article is simply out and out misleading. The only actual "minus" in regards to your ceiling fan is what it requires to get one correctly installed. Ceiling fans could be hard to install for the inexperienced do-it-yourselfer. In some cases, you'll need to run an electrical line to the location where the ceiling fan is to be set up. Unless you're adept at achieving this kind of thing, hiring a capable, bonded and licensed electrician will probably save you much grief in the future.
There is also the minor "disadvantage" that involves the issue of regular maintenance. Correctly installed, a ceiling fan provides years and years of enjoyable cooling and cost-savings on your heating bill (assuming you have a fan which allows you to reverse the blade direction).
On occasion, ceiling fans require minor adjustments and get out of equilibrium. Without going into great detail, be sure that all the screws are tight. If they're not tightening the ones that run the fan and have come loose. Your issue continues to be solved, in the event the wobbling has quit.
If not, make use of a yardstick or other straight part 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 touches. Turn the fan on again and see in the event you've solved the difficulty.
