The answer to 'air duct sealing maintenance tips' is that regularly sealing and maintaining your air ducts can improve the efficiency of your HVAC system, reduce energy costs, and improve indoor air quality. Proper air duct sealing involves inspecting for leaks, cracks, or gaps, and then using mastic sealant or metal foil tape to seal any problem areas.

This is a task that most homeowners can do themselves, but it's important to take safety precautions like wearing protective gear and ensuring proper ventilation. If you have extensive damage or are unsure about the condition of your ducts, it's best to hire a professional HVAC technician to inspect and seal them properly.
