We had Anthony F. (Tony) at our house today to clean our duct work. He was absolutely professional, from his phone call alerting us to his arrival to his putting down drop cloths to his explanation as to what he would do. Our furnace is located in a very small enclosed area and he assured us it would be no problem to work with. It was around 20 degrees outside today. Tony was kind enough to put up a curtain at the front door to hold in a little bit of heat. He went right to work and asked many times if we had any questions. All in all, it would be great if all service people who came to our house were like Tony!
