This house was recently bought and not knowing if the air vents had ever been cleaned and knowing the previous homeowner had animals, I decided to have them cleaned for peace of mind. And I am glad I did because they were filthy. Brandon arrived early and was courteous throughout the process. He kept me informed of what he was doing as he went along and showed me the before and after photos step by step. He clearly explained the process when I had questions. Final product was a stunning transformation. He left things as clean as when he started. I am very happy with the results and will call on Ductworks when we need this job done again. I highly recommend this company and their tech Brandon. John, Littleton
