Installing dimmer switch
I was skimming a real estate book about increasing value of your income property in the bookstore, and it mentioned how much of a difference changing the light on/off switch to a dimmer switch would be.
Does it really make a difference?
And, how hard is install a dimmer switch? I'm looking at the pictures about doing it, and it looks like fairly simple. But, I'm not a handy man. If I did it wrong, would it be a dangerous liability or something?
