Do not use Demmon heating to work on your home he is a very bad person. He is way over his head when it comes to installing heat pumps and should not be doing so. He improperly installed a heat pump at my parents home and within a year it broke down twice. He was to busy to help my parents when they needed him. Good enough to install and make money off them but to busy to take care of then. When I called him out on it he told me to go f#@k myself and hung up on me. Not a good person at all and I hope karma catches up to him. You do not take advantage of people in their mid 70's and treat them poorly. Shame on you Mr. Demmons! read more
