Judy, I agree with the peeps that say get a handy man because they are very easy to install. Why pay an electrician big bucks! Even my hubby, mechanically-challenged, installed a couple of extra ones in our home. And, if he can do it ........ well, you know the rest.
Also, TH, we have them all over the house, fans included, and we've never had any electrical interference problem. Actually we had them in Chicago too and never even heard of the problem your describing.

Are you sure you're not building some kind of Frankenstein monster on that gorgeous lanai of yours?
