      The distance the blades are from the ceiling is very important.   Original ceiling fans were in 9'+ ceiling hanging on a pipe conduit. But then flush mount hangers allowed fans to fit under and 8' ceiling and still not hit your basketball playing 6' 8" son's head.


      That flush type can actually just recirculate the air around and around the blade tips and not blow the air down at all.   If enough air molecules keep bumping into each other again and again with they could actually raise the air temperature just due to friction.


      Get your uncle Jed to blow some see-gar smoke up there to see what is going on.

      Sometimes the fan is too close to the ceiling, it doesnt allow the airflow you are looking for.

      When I  stand  under  a cieling fan I can hardly feel the air blowing?


      I know this:

      The best  blades  need to be at a  certain pitch

      The blades  need to be reversed  for summer and winter accordinly

      You need at least 5 blades  on the fan


      All above things considered, when I stand  near  a standup fan or one of those air  circulators it  feels so much better even when the blades are very small compared  with that  of a celing fan. I have seen the new ceiling fans that look like a two in one and was wondering if this really works or makes a difference since  the blades of the fans are a lot smaller (because  they have to fit two fans in one) for each of the side by side fans.
