How low is too low!

So you have a nice covered patio or porch but the air gets a little still and just wish you had more of a breeze, so what can you do?   Install a ceiling fan!  Brilliant!  Now those fan paddle blades can push that air and create an arctic blast during those hot summer months…  Well, that's not such a good solution when that covered porch or patio ceiling is only around 7' to 8' in height!  That ceiling fan really needs to be no lower than 7' otherwise it stands a good chance of whopping someone upside their head!

The blades on this fan were right at my head when I walked under it.  Just a little too low for comfort.
