How does house leakage testing work?
• A Blower Door is used to depressurize the building shell. • A reading is taken on how much air it takes to depressurize the house. • Based on the volume of the home, an approximate Air Change per Hour (ACH) reading is calculated. • A smoke pen or infrared thermal camera may be used to locate specific leakage areas.
