The cost of replacing ductwork in a house can vary widely depending on several factors, including the size of the house, the complexity of the ductwork system, the materials used, regional labor costs, and any additional modifications required. On average, the cost to replace ductwork in a typical residential home in the United States can range from $2,000 to $5,000 or more.
Here are some factors that can influence the cost:
Size of the House: Larger houses generally require more ductwork, which will increase the overall cost.
Ductwork Material: The type of material used for the ducts affects the cost. Flexible ducts are generally less expensive than rigid metal ducts.
Accessibility: If the existing ductwork is challenging to access or in hard-to-reach areas, it may require additional labor, driving up the cost.
Number of Vents and Returns: The number of vents (supply registers) and returns in the house will impact the cost of replacement.
Sealing and Insulation: Properly sealing and insulating the new ductwork is essential for energy efficiency. If insulation needs replacement or upgrading, it can add to the cost.
HVAC System: If the HVAC system is being replaced or upgraded along with the ductwork, it will add to the overall cost.
Local Labor Costs: Labor costs can vary significantly depending on the region and local market conditions.
It's crucial to get quotes from several HVAC contractors to compare prices and ensure you are getting a fair estimate for your specific situation. Additionally, hiring a reputable and experienced contractor is essential to ensure that the replacement is done correctly and meets local building codes and standards.
Keep in mind that the cost of replacing ductwork is an investment that can improve the efficiency and performance of your HVAC system, leading to potential energy savings and improved indoor comfort.
