Why air sealing matters in California

Reduces heat loss in cold climates
California's cold winters mean uncontrolled air infiltration is a significant source of energy loss. Air sealing dramatically reduces this, especially when combined with insulation.
Required for whole-home heat pump rebates
Many SMUD Rebates for My Home whole-home heat pump rebate paths require verified weatherization. Air sealing is a core part of this — completing it first can unlock higher rebate tiers.
Lower right-sizing risk
A properly air-sealed home needs a smaller heat pump. Oversizing a heat pump leads to short-cycling, humidity problems, and reduced efficiency.
Blower door test verification
Air sealing is measured by a blower door test — a pressure test that quantifies air leakage. Your energy assessor will measure before and after to document improvement.
