Tommy Bahama Ceiling Fan Light Kit - Guess what? The name of the article is simply out-and-out misleading. The sole real "minus" as it pertains to a ceiling fan is what it will take to get one correctly installed. Ceiling fans might be difficult to install for the inexperienced do-it-yourselfer. In some instances, you'll need to run an electrical line to the location where the ceiling fan will be set up. Hiring a competent, bonded and licensed electrician will more than likely save you a lot of grief in the long term, unless you are skillful at achieving this kind of thing.
There's also the minor "minus" that entails the issue of regular care. Correctly installed, a ceiling fan will give you many, many years of enjoyable cooling and cost-savings in your heating bill (assuming there is a fan which allows you to reverse the blade direction). Granted, you should wipe the blades down in a while but everyone has household cleaning chores to take good care of of from time to time.
On occasion, ceiling fans need small alterations and get out of balance. Without going into great detail, make certain that all the screws are tight. When they truly aren't tightening the ones that run the fan and have come loose. If the wobbling has stopped, your problem was solved.
Otherwise, utilize a yardstick or other straight bit of wood and place it (together with the fan stopped) vertically at the outer edge of one of the blades. Rotate the blades by hand to ensure that each blade touches the stick. If one or more don't, just (and gently) bend the blade(s) so that their pitch matches the others and repeat the process until you are satisfied that each blade has the same pitch.
