It's going to be hot again in Louisiana and your ceiling fan can help keep you cool if you have it spinning the proper direction. Which way is yours spinning?
Does your home feel humid all the time? Maybe the temperature seems to fluctuate. Are your floors to your AC vents damp? At night, do you pull the covers up, then off, then up, then off, the same thing night after night? If your HVAC unit is in fine working order and all of these things take place in your home every single day and night, more than likely the fan switch is in the wrong position.
