Duct sealing from the inside — improving comfort and airflow.
Overview
Why Seal Ducts?
Leaky ducts waste conditioned air and cause temperature imbalance. Aeroseal pressurizes the duct system and distributes sealant particles from the inside to close gaps and cracks—without tearing into walls or ceilings.
Benefits
- Better room‑to‑room comfort
- Improved system efficiency
- Measured leakage reduction
- Minimal disruption
Process
How It Works
- Block vents and connect diagnostic equipment.
- Pressurize the system; introduce sealant particles.
- Particles aggregate at leak edges until sealed.
- Verify with post‑test and provide a report.
Applications
Where It Helps
- Existing homes with comfort issues
- New builds needing verified duct tightness
- Multi‑family and light commercial systems
Documentation
What You Receive
- Pre/post leakage numbers (CFM at test pressure)
- Leakage reduction percentage
- Completion certificate
