Different Types Of Ceiling Fan Boxes - Do you know what? The name of the informative article is simply out-and-out misleading. The only actual "con" when it comes to your ceiling fan is what it requires to get one correctly installed. Ceiling fans can be difficult to install for the inexperienced do it yourselfer. Sometimes, where the ceiling fan will be to be installed you'll need to run an electrical line to the region. Unless you're adept at doing this kind of thing, hiring a licensed, bonded and capable electrician will more than likely save you much grief in the long run.
There's also the minor "con" that entails the issue of periodic maintenance. Properly installed, a ceiling fan provides many, many years of agreeable cooling and cost-savings on your heat bill (assuming you have a fan that allows you to reverse the blade direction). Allowed, you need to wipe down the blades in a while but everyone has household cleaning chores to take care of from time to time.
On occasion, ceiling fans get out of equilibrium and need slight adjustments. The most common culprits are loose screws that attach the blades to the motor housing, blades which aren't at the same angle (pitch) as the rest of the blades and also a blade or blades that weigh slightly more compared to the others. Without going into great detail, be certain that every one of the screws are tight. Whenever they aren't tightening the ones that have come loose and run the fan. Your problem has been solved, when the wobbling has ceased.
Otherwise, use a yardstick or other straight bit of wood and place it (with the fan quit) vertically at the outer edge of one of the blades. Rotate the blades by hand to make sure that the stick is touched by every blade. If one or more don't, only (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. Turn the fan on again and see if you have solved the difficulty.
