Why leaky ducts cost you

  • System performance. Duct conditions can be evaluated as part of a whole-home inspection.
  • Comfort. Rooms far from the air handler get weak airflow, creating hot and cold spots.
  • Airflow. Ductwork can be assessed alongside attic and ventilation conditions.
  • HVAC planning. Recommendations can consider your system alongside attic and duct conditions.
