Light Switch Ceiling Fan Remote - You know what? The name of the article is only out and out misleading. The only actual "con" as it pertains to your ceiling fan is what it takes to get one correctly installed. Ceiling fans may be hard to install for the inexperienced do it yourselfer. Sometimes, you'll need to run an electric line to the area where the ceiling fan will be installed. Hiring a qualified, bonded and licensed electrician will most likely save you much grief in the long term, unless you're adept at achieving this sort of thing.
There's also the minor "con" that involves the problem of regular care. Correctly installed, a ceiling fan will provide years and years of pleasant cooling and cost-savings on your heat bill (assuming you've got a fan that enables you to reverse the blade direction).
On occasion, ceiling fans require slight alterations and get out of balance. Be certain that all the screws are tight, without going into great detail. If they truly aren't tightening the ones that run the fan and have come loose. When the wobbling has stopped, your problem continues to be solved.
Otherwise, make use of a yardstick or another straight bit of wood and place it (together with the fan stopped) vertically at the outer edge of among the blades. Rotate the blades by hand to be certain that each blade touches the stick. If one or more don't, only (and gradually) 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 have solved the problem.
