Industrial Grade Outdoor Ceiling Fans - Do you know what? The name of the article is just out and out misleading. The only actual "con" in regards to your ceiling fan is what it takes to get one correctly installed. Ceiling fans can be difficult to install for the inexperienced do it yourselfer. In some cases, where the ceiling fan will be to be installed, you will need to run an electric line to the location. Hiring a capable, bonded and licensed electrician will most likely save you much grief in the future, unless you are adept at doing this kind of thing.
There is also the minor "disadvantage" that entails the problem of regular care. Properly installed, a ceiling fan provides years and years of pleasant cooling and cost-savings on your own heating bill (assuming you have a fan which allows one to reverse the blade direction). Granted, you need to wipe the blades down once in a while but then, everyone has household cleaning chores to take care of from time to time.
On occasion, ceiling fans require slight alterations and get out of equilibrium. The most typical culprits are loose screws that attach the blades to the motor housing, blades which are not at precisely the same angle (pitch) as the remaining blades as well as a blade or blades that weigh slightly more in relation to the others. Be certain that all of the screws are tight without going into great detail. When they're not tightening the ones that run the fan and have come loose. In the event the wobbling has stopped, your issue continues to be solved.
Otherwise, make use of a yardstick or other straight piece 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 each blade touches the stick. If one or more don't, just (and gradually) 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 problem.
