Air Duct Sealing Process And Timeline

Sealing air ducts is a step-by-step process designed to stop air leaks, improve airflow, and increase energy efficiency. The process typically starts with a full inspection to identify where air is escaping. From there, the best sealing method is chosen based on the condition and accessibility of your ductwork. Here’s how duct sealing usually works:

  • Inspect the duct system for leaks, gaps, or disconnected sections
  • Measure airflow or leakage to understand system performance
  • Seal leaks using mastic, tape, or Aeroseal depending on the situation
  • Re-test the system to confirm improved performance

The time required depends on the size of your home and how extensive the leaks are:

  • Minor sealing: A few hours
  • Standard home: Half day to full day
  • Larger or complex systems: May take longer

In the Texas Hill Country, where ductwork is often exposed to extreme attic temperatures, sealing leaks can make a significant difference in comfort and efficiency. 72 Degrees Texas provides professional duct sealing services in Fredericksburg, Kerrville, and surrounding areas, helping ensure your system runs efficiently with minimal air loss.
