What Is Duct Sealing?
Duct sealing is the systematic process of identifying and closing air leaks in your home's ductwork system using specialized materials and techniques. The physics behind duct sealing centers on static pressure optimization – when air escapes through gaps, joints, and deteriorated connections, your HVAC system's blower motor must work harder to maintain designed airflow rates, typically measured in cubic feet per minute (CFM).
Professional duct sealing involves two primary methodologies: aeroseal technology, which uses aerosolized polymer particles that automatically collect at leak points under pressurized conditions, and manual sealing, where technicians apply mastic sealant, metallic tape, or specialized gaskets to visible gaps and disconnected joints. The process targets common failure points including plenum connections, branch takeoffs, register boots, and flex duct connections where movement and age cause separation.
Modern duct systems operate under positive pressure ranging from 0.5 to 2.0 inches of water column. When leaks compromise this pressure, the system experiences pressure drop, forcing equipment to run longer cycles and consume more energy. Professional sealing restores designed pressure relationships, improving both comfort delivery and system efficiency.
Homeowners typically require duct sealing when experiencing short-cycling behavior from their HVAC equipment, uneven temperatures between rooms, excessive dust accumulation, or utility bills that spike unexpectedly. In Livermore's climate, these issues become particularly apparent during summer months when AC systems struggle to maintain comfortable indoor temperatures despite continuous operation.
