The Hidden Impact of Ductwork
Ducts distribute conditioned air throughout your home. Poor ductwork can waste 25-40% of heating and cooling energy—more than any other component.
Common Ductwork Problems
Leaky connections, crushed flex duct, undersized runs, poor insulation, and restrictive turns all reduce system performance significantly.
Signs of Duct Problems
Some rooms too hot or cold. Higher-than-expected energy bills. Excessive dust. Noise from ducts. Poor airflow from registers.
Duct Leakage Testing
Duct blaster tests measure total leakage. Many homes lose 20-30% of airflow through duct leaks. Sealing to under 10% leakage significantly improves efficiency.
Duct Sealing Options
Mastic sealant and metal tape seal accessible leaks. Aerosol duct sealing (Aeroseal) seals from inside, reaching inaccessible areas.
When Duct Replacement Is Needed
Severely damaged, undersized, or poorly designed ductwork may need replacement. This is often done during HVAC replacement for optimal matching.
