Attic Ceiling Fan Shutter - Do you know what? The title of the article is merely out and out misleading. The sole actual "disadvantage" when it comes to a ceiling fan is what it takes to get one correctly installed. Ceiling fans could be hard to install for the inexperienced do it yourselfer. In some cases, where the ceiling fan would be to be installed you will need to run an electric line to the area. Unless you're adept at doing this type of thing, hiring a licensed, bonded and capable electrician will more than likely save you much grief in the future.
There's also the minor "minus" that involves the problem of regular maintenance. Properly installed, a ceiling fan will give you years and years of nice cooling and cost-savings in your heat bill (assuming there is a fan that allows you to reverse the blade direction).
On occasion, ceiling fans require slight alterations and get out of balance. The most typical offenders are loose screws that attach the blades to the motor housing, blades that are not at exactly the same angle (pitch) as the rest of the blades as well as a blade or blades that weigh slightly more compared to the others. Ensure that every one of the screws are tight without going into great detail. If they're not tightening the ones that run the fan and have come loose. Your problem has been solved in the event the wobbling has ceased.
If not, make use of a yardstick or other straight part of wood and place it (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. Turn the fan on again and see in the event you've solved the problem.
