Cathedral Ceiling Fan Mounting Block - Do you know what? The title of this informative article is just out and out misleading. The sole actual "con" in regards to a ceiling fan is what it takes to get one properly installed. Ceiling fans might be difficult to install for the inexperienced do-it-yourselfer. In some instances, where the ceiling fan will be set up, you'll need to run an electrical line to the area. Hiring a qualified, bonded and licensed electrician will most likely save you much grief in the long term, unless you are adept at achieving this type of thing.
There's also the minor "disadvantage" that entails the issue of periodic care. Properly installed, a ceiling fan will give you many, many years of enjoyable cooling and cost-savings on your heating bill (assuming there is a fan that allows you to reverse the blade direction).
On occasion, ceiling fans get out of equilibrium and require small adjustments. The most common culprits are loose screws that attach the blades to the motor casing, blades that aren't at exactly the same angle (pitch) as the rest of the blades and also a blade or blades that weigh slightly more in relation to the others. Without going into great detail, make certain that all the screws are tight. Whenever they truly aren't tightening the ones that run the fan and have come loose. When the wobbling has stopped, your issue continues to be solved.
If not, utilize a yardstick or another straight bit of wood and put it (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.
