Benefits of Having Your Ducts Sealed

  • Increases Comfort: Sealing your ducts ensures consistent airflow throughout your home, preventing hot and cold spots and enhancing overall comfort.​
  • Saves Money: Properly sealed ducts ensure that more conditioned air reaches your living spaces, reducing the operational time of your HVAC system and lowering energy bills.​
  • Protects Your Health: Leaky ducts can introduce dust, mold, and other contaminants into your home’s air. Sealing your ducts helps maintain indoor air quality, safeguarding your household’s health.

For a detailed understanding of duct sealing costs, contact us for a free in-home estimate.


  • Size of Your Home: Larger homes typically have more extensive ductwork, increasing the scope and cost of the sealing project.​
  • Duct Sealing vs. Replacement: If your ductwork has extensive leaks or gaps, replacement might be more cost-effective than sealing in the long run.​
  • Accessibility of Ducts: Ducts located in hard-to-reach areas may require additional labor, increasing the overall cost.​
  • System Orientation: Vertical HVAC systems may incur higher sealing costs due to increased material needs and labor time compared to horizontal systems.

Consider Scheduling Duct Sealing When:

  • Hot or Cold Spots in Your Home: Inconsistent temperatures across rooms indicate potential duct leaks.​
  • High Utility Bills: Unexpectedly high energy bills, even with newer HVAC equipment, can result from leaky ducts.​
  • High Indoor Humidity: Certain rooms experiencing elevated humidity levels may suggest duct issues.​
  • Dusty Environment: A persistently dusty home, despite regular cleaning, can be a sign of duct leaks.​
  • Health Concerns: Unexplained allergies or respiratory issues among occupants may be linked to contaminated air from leaky ducts.​
  • Visible Damage: Observable holes or tears in your ductwork necessitate immediate sealing.
