Clipsal High Performance Ceiling Fan - You know what? The name of the informative article is only out and out misleading. The sole actual "disadvantage" when it comes to a ceiling fan is what it will take to get one properly installed. Ceiling fans might be difficult to install for the inexperienced do-it-yourselfer. Sometimes, where the ceiling fan is to be installed, you will need to run an electrical line to the place. Unless you are skillful at doing this kind of thing, hiring a qualified, bonded and licensed electrician will most likely save you much grief in the long run.
There is also the minor "con" that entails the issue of regular care. Properly installed, a ceiling fan will provide many, many years of nice cooling and cost-savings in your heat bill (assuming you've got a fan that enables you to reverse the blade direction). Granted, you need to wipe the blades down once in a while but everyone has household cleaning chores to take care of from time to time.
On occasion, ceiling fans need slight alterations and get out of balance. The most typical culprits are loose screws that attach the blades to the motor casing, blades which aren't at precisely the same angle (pitch) as the remaining blades as well as a blade or blades that weigh somewhat more compared to the others. Be sure that all of the screws are tight without going into great detail. Whenever they're not tightening the ones that have come loose and run the fan. If the wobbling has ceased, your problem has been solved.
Otherwise, use a yardstick or another straight piece 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 make sure that every blade touches the stick. If one or more do not, only (and gently) bend the blade(s) so that their pitch matches the others and repeat the procedure until you are satisfied that each blade has the same pitch. Turn the fan on again and see in the event you've solved the difficulty.
