The average cost to replace ductwork in a residential home typically ranges from $3,000 to $7,500, though complex or large projects can exceed $10,000. This wide range depends heavily on factors like the home's size, the duct system's accessibility, the materials chosen (e.g., flexible vs. sheet metal), and regional labor rates. A full replacement involves removing old ducts, installing new ones, and ensuring proper sealing and insulation to meet current efficiency standards. Investing in a modern, properly sized and sealed system can significantly improve indoor air quality and reduce energy bills. It is crucial to obtain multiple detailed estimates from licensed, insured HVAC contractors who perform a thorough home evaluation.

The $5000 rule in HVAC is a guideline used to decide whether to repair or replace an existing air conditioning system. It suggests that if the cost of a needed repair multiplied by the age of the unit (in years) exceeds $5000, replacement is often the more economical long-term choice. For example, a $1000 repair on a 10-year-old unit (1000 x 10 = 10,000) would point toward replacement. This rule helps homeowners weigh the investment in an old, potentially inefficient system against the benefits of a new, reliable, and energy-efficient model. It is a general heuristic, and the final decision should also consider the system's overall condition, efficiency gains, and future repair likelihood.
The cost of ductwork for a 2000 square foot house typically ranges from $4,000 to $12,000, with a national average around $6,000 to $8,000. This wide variation depends heavily on the project scope. A full new installation in a house without existing ducts is at the higher end, while replacing or repairing sections of old ductwork costs less. Key factors include the home's layout, the HVAC system's size and efficiency, the type of duct material (flexible, sheet metal, or fiberglass), local labor rates, and whether insulation or complex sealing is required. For an accurate estimate, it is essential to get multiple quotes from licensed professionals who can assess your specific home and needs.
