The answer to how much to fix air duct sealing in Chicago can vary widely, but typically ranges from $500 to $2,000 or more. The exact cost will depend on factors like the size of your home, the accessibility of the ductwork, the extent of the sealing needed, and whether any ductwork repairs are required.
Proper air duct sealing is an important HVAC maintenance task that can improve your home's energy efficiency, indoor air quality, and overall comfort. It involves using mastic sealant or metal tape to close any gaps, cracks, or leaks in the ductwork. This prevents conditioned air from escaping, which can lead to higher energy bills and uneven heating/cooling.
