How Duct Sealing Works
Duct sealing uses mastic sealant, metal tape, or aerosol sealing (Aeroseal) to close gaps and leaks in ductwork. Starts with pressure testing to quantify leakage, then systematic sealing of accessible joints and connections. Can reduce HVAC energy use by 20-30% in leaky systems.
