Outdoor Double Oscillating Ceiling Fans - Guess what? The name of the article is merely out and out misleading. The sole actual "minus" in regards to your ceiling fan is what it requires to get one correctly installed. Ceiling fans could be difficult to install for the inexperienced do-it-yourselfer. In some cases, you'll need to run an electric line to the region where the ceiling fan would be to be installed. Unless you are skillful at doing this kind of thing, hiring a capable, bonded and licensed electrician will more than likely save you much grief in the long term.
There's also the minor "minus" that entails the issue of regular maintenance. Correctly installed, a ceiling fan will provide many, many years of enjoyable cooling and cost-savings on your own heating bill (assuming there is a fan that enables you to reverse the blade direction). Allowed, you should 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 small adjustments. The most frequent culprits are loose screws that attach the blades to the motor casing, blades that are not at exactly the same angle (pitch) as the remaining blades and also a blade or blades that weigh slightly more in relation to the others. Without going into great detail, be sure that every one of the screws are tight. If they truly aren't tightening the ones that run the fan and have come loose. When the wobbling has ceased, your issue continues to be solved.
If not, use a yardstick or other straight part of wood and put it (together with the fan quit) vertically in the outer edge of one of the blades. Rotate the blades by hand to make sure that the stick touches.
