How Much to Repair Ductwork?

Ductwork is an important component of your HVAC system as it carries heated or cooled air throughout your home. Over time, ductwork can develop leaks, holes, or cracks, which can lead to energy loss and decreased efficiency of your system. In order to maintain a comfortable temperature in your home and keep your energy bills low, it is important to repair ductwork as soon as possible.

Assessment of Damage

The first step in repairing ductwork is to assess the extent of the damage. A professional HVAC technician can perform a visual inspection of your ductwork and use specialized tools to detect leaks or cracks in the system. The technician can also check for any blockages in the ducts that might be preventing air flow. Based on the assessment, the technician can determine the extent and cost of the repairs needed.

Types of Repairs

The cost of repairing ductwork can vary depending on the type and extent of the damage. Some common types of repairs include:

  • Sealing leaks and cracks: If there are small leaks or cracks in the ductwork, they can be easily sealed with duct tape or a special sealing compound. This is a simple and inexpensive repair that can improve the efficiency of your system.
  • Patching holes: If there are larger holes in the ductwork, they will need to be patched with metal or plastic patches. This repair is more complicated and will require more time and materials.
  • Replacing damaged ducts: If the ductwork is extensively damaged, it may need to be replaced entirely. This is the most expensive option, but it will provide a long-term solution to your ductwork problems.

Costs of Repairing Ductwork

The cost of repairing ductwork can vary widely depending on the type and extent of the repairs needed. If you only need a few small leaks sealed, the cost may be less than $100. However, if you need extensive repairs or replacement of your ductwork, the cost can be several thousand dollars.

According to HomeAdvisor, the average cost of repairing ductwork is around $350. However, this can vary widely depending on the size of your home, the extent of the damage, and the materials needed for repairs.


Repairing ductwork is an important part of maintaining your HVAC system and ensuring that your home is comfortable and energy efficient. While the cost of repairs can vary widely, it is important to have your ductwork assessed by a professional HVAC technician to determine the extent of the repairs needed and the cost involved. By catching ductwork problems early and making necessary repairs, you can keep your home heating and cooling system running smoothly and keep your energy bills low.
