I would have no hesitations recommending Ductworks and Sani. Sani was prompt, professional and took the time to explain the process in detail to me. I didn't realize how long the cleaning process took and had scheduled carpet cleaning the same day. Sani worked through his lunch to accommodate my carpet cleaning. After the cleaning process, he showed me before and after pictures. I was surprised to see how dirty my air duct and trunk lines were. There was a very visible difference before cleaning and after. I will certainly call Ductworks again and request Sani. They are fortunate to have such a great employee.
