technicians were excellent I am satisfied they did the best they could with the complexity of the fully finished house without making damage thank you all

Thank You Randy for the 5 star review. We do have a series of tools that travel the main lines of the ductwork from the furance room so we are very confident that your main trunk lines are dust and construction debris free. These tools whip the walls of the ductwork and retrieve debris like wood and drywall. As always we put a one year warranty on all our work .
