How Can I Seal a Leaking Air Duct to Improve HVAC Efficiency?

Sealing a leaking air duct does improve HVAC efficiency by stopping heated or cooled air from escaping. Gold Star provides duct sealing, ventilation inspections, and filter maintenance to restore airflow and comfort as part of our indoor air quality services. A licensed technician will inspect, locate leaks, and seal them, then confirm system performance with our diagnostic process and upfront pricing.

Quick checks before we arrive:

  • Look or listen for air escaping at joints and vents.
  • Make sure registers are fully open.
  • Replace a dirty HVAC filter.
