Alpha Micro Ceiling Fan - Guess what? The name of this informative article is just out and out misleading. The sole real "con" in regards to your 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 instances, you'll need to run an electrical line to the location where the ceiling fan is to be set up. Hiring a capable, bonded and licensed electrician will probably save you much grief in the long term unless you're skillful at doing this kind of thing.
There's also the minor "disadvantage" that involves the issue of regular care. Properly installed, a ceiling fan will provide years and years of nice cooling and cost-savings on your own heating bill (assuming you have a fan which allows you to reverse the blade direction).
On occasion, ceiling fans get out of balance and require minor adjustments. The most frequent culprits are loose screws that attach the blades to the motor housing, blades that are not at the same angle (pitch) as the remaining blades as well as a blade or blades that weigh slightly more in relation to the others. Make certain that every one of the screws are tight, without going into great detail. If they aren't tightening the ones that have come loose and run the fan. Your issue has been solved, when the wobbling has stopped.
Otherwise, make use of a yardstick or other straight part of wood and place it (with the fan stopped) vertically at the outer edge of among the blades. Rotate the blades by hand to be certain that every blade touches the stick. If one or more do not, just (and gradually) bend the blade(s) so that their pitch matches the others and repeat the procedure until you're satisfied that each blade has the same pitch.
