Electrical Box For Ceiling Fan Support - You know what? The title of the article is simply out-and-out misleading. The only real "con" in regards to some ceiling fan is what it will take to get one properly installed. Ceiling fans may be hard to install for the inexperienced do it yourselfer. Sometimes, where the ceiling fan would be to be installed, you will need to run an electrical line to the location. Hiring a qualified, bonded and licensed electrician will probably save you much grief in the long term, unless you are skillful at achieving this sort of thing.
There is also the minor "minus" that involves the issue of regular care. Properly installed, a ceiling fan provides years and years of pleasant cooling and cost-savings in your heat bill (assuming you've got a fan which allows you to reverse the blade direction). Allowed, you have to wipe the blades down 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 need minor adjustments. The most frequent culprits are loose screws that attach the blades to the motor casing, blades which are not at the same angle (pitch) as the remaining blades and also a blade or blades that weigh somewhat more compared to the others. Without going into great detail, be sure that every one of the screws are tight. If they're not tightening the ones that run the fan and have come loose. In the event the wobbling has quit, your issue continues to be solved.
Otherwise, utilize a yardstick or other straight bit of wood and put it (together with the fan quit) vertically in the outer edge of one of the blades. Rotate the blades by hand to ensure that the stick is touched by every blade. Turn the fan on again and see if you have solved the problem.
