Blower Door Tests

Blower door testing is a precise diagnostic method used to measure a building’s air tightness and identify sources of energy loss. By using specialized equipment to create a controlled pressure difference between the interior and exterior, this test reveals hidden air leaks that can compromise comfort, efficiency, and indoor air quality.

Our certified technicians conduct blower door tests in accordance with industry standards to deliver accurate, reliable results. During the process, a high-powered fan is temporarily installed in an exterior doorway to depressurize the building, allowing us to pinpoint leaks around windows, doors, ductwork, insulation gaps, and other structural penetrations.

The data collected provides valuable insights into how your building performs, helping guide targeted improvements that reduce energy costs, enhance comfort, and ensure compliance with energy codes and performance requirements. Blower door testing is often essential for new construction verification, energy audits, and weatherization projects.

Whether you are a homeowner, builder, or contractor, our blower door testing services offer a clear path to improved efficiency, better air quality, and long-term building performance.
