Ceiling Fan FAQs

Are they Evil??

Ceiling fans would seem, at first glance, to be a smart tool in the overall mix of your home's energy efficency equipment. But too few know that their real value is when they're blowing on people--and many experts say they're essentially worthless and counterproductive if people aren't present in the home. Carl Seville, a Green Building Consultant and expert from Atlanta, wrote a provocatively named post recently: Ceiling Fans are Evil on the Green Building Advisor blog.

Here's a direct quote: "I am not suggesting that we should not use ceiling fans — just that they shouldn’t be on if no one is in the room. If people only use them when necessary and set their thermostat a bit higher, then the extra heat is a small price to pay for the comfort and energy savings."

Do you leave your fans on when no one is home?

Should I use them during the winter? 

You might say no - I mean, most of us hear 'ceiling fan' and think 'cooling off in summer.'  But is that really their only use?  ENERGYStar says no... http://www.energystar.gov/index.cfm?c=ceiling_fans.pr_ceiling_fans_usage and points out that direction is everything.  (how many of us have ever used that direction switch? It's there, might be dusty, but it's there...)

Blade Size... Does it matter? 

The nice people at Freshen Up Your Home seem to think it does.  And they have a point - the goal is to push air, and like any fan you should match it to your room size.  Position plays a big part in it too - off center might look nice, but it's robbing you of valuable savings!  You installed the fan to save you money after all.   http://freshenupyourhome.com/ceiling-fans-do-the-blades-make-a-difference/
