How much does it cost to replace ductwork in a 2000 square foot house?

Replacing the entire residential heating and cooling ductwork system in a typical two-thousand-square-foot home generally ranges in cost from four thousand to ten thousand dollars, depending heavily on the complexity of the layout, the chosen duct materials (flexible ducting versus rigid sheet metal), accessibility in attics or crawlspaces, and local labor rates. A straightforward replacement in a home with an open, easily accessible basement and drop ceiling will sit on the lower end of that price spectrum, whereas a multi-story home with complex, cramped attic runs requiring complete demolition and custom sheet metal fabrication will approach the higher end. You can evaluate pricing by obtaining multiple written contractor quotes. You can verify value when detailed estimates break down materials and labor clearly.
