The answer to 'how to maintain air duct sealing' is to regularly inspect and seal any gaps or leaks in your air ducts. This helps improve energy efficiency, indoor air quality, and the overall performance of your HVAC system. Start by visually inspecting all accessible ducts for any cracks, holes, or loose connections. Use a duct sealing mastic or metallic tape to patch any leaks you find. It's also important to clean your ducts periodically to remove dust and debris that can interfere with airflow.
For best results, schedule professional duct cleaning and sealing every 3-5 years, or if you notice a significant drop in HVAC efficiency or uneven temperatures throughout your home. A professional HVAC technician has the right tools and expertise to thoroughly inspect, clean, and seal your entire duct system to maximize its performance and lifespan.
