Friend had a humidistat installed and said the contractor assured him he would save enough money to pay for it in a few years. I called my guy, Chuck Farrell (the very best local company IMO), and asked him to install one for me. He said it would take at least twenty years to recoup the original cost of a humidistat plus installation. Three years later, my friend is a little embarrassed that his summer bills with a humidistat are the same as they were when he formerly just set the AC to 84.
