Greg came to our house to do extensive work on our furnace in the Fall 2018. Now January 2019 and it has broken down twice. First time he said he was on vacation, call Hamco. hamco came and questioned his work. Broke down again.... Now he says he is retired!!! You should probably take him off the Home Stars site! Terrible service. Never told us he was retiring. We never would have used him if he was not going to stand behind his work. Not sure what yuo were doing the last 40 years!
