Receive a detailed home performance report How the Test Works We install a calibrated blower door in an exterior doorway to safely depressurize your home. Using professional diagnostic equipment, we identify where conditioned air is escaping and outside air is entering. You’ll receive clear findings and recommendations to improve your home’s energy efficiency and comfort.
Many homeowners are unaware of how much energy is lost through hidden air leakage. Even small gaps and cracks throughout a home’s envelope can add up to significant energy loss over time. A blower door test provides measurable data that takes the guesswork out of home performance improvements and helps ensure that upgrades are focused where they will deliver the most value.
Our team carefully analyzes the results and explains what they mean in practical terms. We identify the most significant leakage areas, discuss their impact on comfort and efficiency, and provide recommendations tailored to your home’s specific conditions. This information can be especially valuable before undertaking air sealing projects, attic insulation upgrades, HVAC improvements, or major renovations.
Blower door testing is also commonly used to verify the effectiveness of completed upgrades. By comparing results before and after improvements, homeowners can see measurable evidence of reduced air leakage and better overall home performance.
A blower door test measures the amount of air leaking through your home’s exterior envelope. It helps identify hidden gaps and openings that may contribute to energy loss, drafts, and comfort issues.
Most residential blower door tests can be completed within one to two hours, depending on the size and complexity of the home. Additional time may be required if detailed reporting is requested.
The test itself does not reduce energy costs, but it identifies areas where improvements can be made. Addressing air leakage often helps reduce energy waste and improve HVAC efficiency.
A blower door test is beneficial whether you’re purchasing a home or have lived in your home for years. It’s ideal if you’re experiencing high energy bills, uneven room temperatures, drafts, excessive dust, humidity issues, or suspect hidden air leaks. It’s also recommended before and after air sealing, insulation upgrades, HVAC improvements, renovations, or to verify your home’s overall energy performance.
