Regardless of if you have a home office or work place facility, don't forget to clean your fan! I was picking up a bit around my work area/home office room and started to sweat. I'd just returned from the outside and thought, "it wasn't that hot out there".
I know that heat is trapped inside of a building, but still, it was warmer than usual. I was going to reach over to turn on the fan, but noticed that it was already on. Dusty, but on. It wasn't properly moving and circulating the air. But, let me tell you something. Taking 5 minutes to take the fan apart to clean the plastic blades and frame guard made a world of difference!
There was such an increase of airflow, and you could feel the room cool down almost immediately--and it wasn't even on high.
