I don't know where these guys received their training, but Jerry needs a refresher course. I am out of almost $8,000.00 dealing with that moron Jerry. I hope to God they have fired his dumb butt. Everytime I drive my house and look at the unit I had to cover out of my own pocket, because he provided wrong information to my home warranty company I could kick his sorry butt. Whatever you decide do not let him come to your house by himself make certain one of the other guys is with him.
