Ceiling Fans Too Close To Ceiling - Guess what? The name of this article is only out and out misleading. The sole real "con" as it pertains to your ceiling fan is what it requires to get one correctly installed. Ceiling fans could 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 electric line to the area. Hiring a capable, bonded and licensed electrician will probably save you much grief in the long term unless you're adept at doing this sort of thing.
There is also the minor "con" that entails the problem of regular care. Properly installed, a ceiling fan will give you years and years of pleasant cooling and cost-savings in your heating bill (assuming you've got a fan that enables one to reverse the blade direction).
On occasion, ceiling fans get out of balance and need minor alterations. The most frequent offenders are loose screws that attach the blades to the motor housing, blades that aren't at the same angle (pitch) as the rest of the blades as well as a blade or blades that weigh slightly more than the others. Without going into great detail, make sure that all of the screws are tight. If they truly aren't tightening the ones that have come loose and run the fan. If the wobbling has quit, your problem continues to be solved.
If not, utilize a yardstick or other straight bit of wood and put it (with the fan stopped) vertically at the outer edge of among the blades. Rotate the blades by hand to make sure that the stick is touched by each blade. If one or more don't, simply (and gently) bend the blade(s) so that their pitch matches the others and repeat the process until you're satisfied that each blade has the same pitch. Turn the fan on again and see in the event you've solved the problem.
