Duct Sealing | Shreveport, LA

Signs Your Ducts Need Sealing

Many homeowners live with duct leakage for years without realizing it. Watch for these indicators:

• Rooms that never quite reach the thermostat setting, especially upstairs or at the end of long duct runs
• Utility bills that seem high relative to your home size and system age
• Excessive dust accumulation or musty odors in certain rooms
• Visible gaps, disconnected sections, or damaged flex duct in the attic or crawlspace
• AC or furnace that runs constantly but struggles to keep up during peak weather
• Noticeable temperature swings or uneven comfort between rooms
• Recent HVAC tune-up revealed low airflow or pressure imbalances

Our Duct Sealing Process

Southern Air approaches duct sealing as a system-level improvement, not a quick patch job. Here’s what to expect:

• Inspection and assessment: We examine your entire duct system, supply and return, looking for leaks, disconnected sections, poor original installation, and airflow restrictions.
• Leak detection: Using visual inspection, pressure testing, and airflow measurement, we identify where conditioned air is escaping and quantify the severity.
• Sealing strategy: We recommend the right approach for your system, mastic and mesh for accessible joints, aerosol sealing for hard-to-reach leaks, mechanical fasteners for loose connections.
• Professional sealing: Our technicians seal every identified leak using proven materials and techniques that meet or exceed industry standards.
• Testing and verification: After sealing, we retest airflow and system performance to confirm the improvement and ensure balanced delivery to all rooms.
• Walkthrough and documentation: We explain what we found, what we fixed, and what you can expect in terms of comfort and efficiency gains.

Duct Sealing vs. Full Duct Replacement

Not every duct system needs to be replaced. If your ductwork is structurally sound, properly sized, and well-designed, professional sealing can restore performance at a fraction of the cost of replacement. We’ll always tell you if sealing alone will solve the problem.

However, if ducts are severely damaged, collapsed, undersized for your current equipment, or poorly routed with excessive bends and restrictions, replacement may be the smarter long-term investment. In those cases, we’ll provide clear options and explain the performance and efficiency differences so you can make an informed decision. Our goal is the right solution for your home, not the most expensive one.
