The answer to 'how does air duct sealing work' is that air duct sealing is a process of identifying and sealing leaks in a home's ductwork system. This helps improve the efficiency of the HVAC system by reducing air leaks and ensuring conditioned air is delivered effectively throughout the home. Duct sealing typically involves inspecting the ductwork, locating any gaps or cracks, and using specialized sealants or mastic to close those leaks.
Proper air duct sealing can provide several benefits, including improved indoor air quality, reduced energy costs, and a more comfortable living environment. It's an important maintenance task for homeowners to consider, especially if they notice uneven heating/cooling, high energy bills, or dust/allergen issues in their home.
