How long does it take to replace ductwork?

The total time required to replace residential heating and cooling ductwork in a typical single-family home generally ranges from one to three days, depending heavily on the size of the house, the complexity of the duct layout, and whether the work is performed by a crew of experienced professional technicians. A straightforward duct replacement in a single-story home with an open basement and accessible drop ceilings can often be completed in a single day, whereas a multi-story home with cramped, multi-run attic spaces requiring custom sheet metal fabrication can take two to three full days of intense labor. You can plan ahead by asking your HVAC contractor for a detailed timeline before work begins. You can verify that the project is progressing correctly when old runs are removed and new, insulated ducts are securely hung.
