Small Ceiling Fans With Light Flush Mount - You know what? The name of the informative article is simply out and out misleading. The sole real "minus" as it pertains to some ceiling fan is what it will take to get one correctly installed. Ceiling fans can be hard to install for the inexperienced do-it-yourselfer. In some cases, where the ceiling fan is to be installed you'll need to run an electric line to the location. Unless you are adept at achieving this kind of thing, hiring an authorized, bonded and competent electrician will more than likely save you a lot of grief in the long run.
There's also the minor "minus" that entails the problem of regular care. Properly installed, a ceiling fan will give you many, many years of nice cooling and cost-savings in your heat bill (assuming you have a fan that enables one to reverse the blade direction).
On occasion, ceiling fans get out of equilibrium and require minor adjustments. Make sure that all the screws are tight without going into great detail. When they truly aren't tightening the ones that run the fan and have come loose. Your issue has been solved, when the wobbling has ceased.
Otherwise, use a yardstick or another straight bit of wood and put it (together with the fan quit) vertically at the outer edge of among the blades. Rotate the blades by hand to make sure that every blade touches the stick.
