Before committing to this new project, you’re likely weighing the pros and cons of attic fans. The good news is that typical roof vents can only ventilate 150 to 300 square feet per unit, whereas a single attic fan can circulate enough air to vent an entire attic. By moving large volumes of air within and out of the attic space, an attic fan can lower the temperature by 15 to 40 degrees Fahrenheit and reduce moisture to prevent mold and mildew.

If your fan blades are spinning and there is no airflow, your blade pitch may be too flat, or your motor is failing. Adjusting the pitch is a simple DIY task if you have the tools. A failing motor is a bigger problem. You may need to replace your ceiling fan altogether. But fret not, we’ve got a guide for that!

The number of blades for your fan poses both advantages and disadvantages. Typically, the more blades on a fan, the better the air distribution and cooling effect, but this also means that your fan will have more wear on its motor. For small rooms, three-blade fans should work fine. For larger areas like living rooms, four or five-blade fans might be the better option. 

You should generally avoid using WD-40 on a ceiling fan. While it might quiet a squeak temporarily, it is primarily an anti-corrosion and water displacement agent, not a true lubricant, and can damage the fan's components over time. Most modern ceiling fans have sealed bearings and do not require oiling, so a squeak may indicate another issue. For fans that do require lubrication, it is better to use a light machine oil, 30-weight motor oil, or a lubricant specifically designed for ceiling fans.
