Dial One Professional Duct Cleaning

I am going to have my furnace replaced in few days; I wanted my ducts cleaned before installing the new furnace, so I can have a clean start with the new furnace. Joe came with his red amazing powerful truck, I had doubt first how can he does a good job alone, but after seeing Joe navigates and operates easily, he also showed me how much dust fly through inside my dirty duct, I am finally convinced my duct would be clean after his job done, Joe spent more than two hours to complete the job. Thanks Joe! Job well done.
