Blower Door Testing

• Certified diagnostic testing to measure building efficiency.
• Reduce air leakage and meet energy code compliance.
• Required in many states for new construction and major renovations to comply with energy codes.
• This test identifies air leaks, improves energy performance, and helps qualify for utility rebate programs.

Blower door testing is often required to confirm that a building is properly sealed and meets energy efficiency expectation before final approval.

It is commonly required in situations such as:

• New construction projects where airtightness must be confirmed before final inspection
• Major renovations or additions that affect the building envelope
• Before final inspections to confirm compliance with local and national energy codes
• When documentation is required for inspectors, permitting, or project approvals

In most cases, blower door testing helps identify air leaks early, reducing the risk of failed inspections, approval delays, or costly rework later in the project.

Poor airtightness leads to energy loss, inconsistent temperatures, higher utility bills, and code violations. Blower door testing is essential for:

• Meeting local and national energy code requirements
• Verifying insulation and air sealing effectiveness
• Identifying hidden drafts or leaks before final inspections
• Increasing comfort and indoor air quality
• Reducing HVAC system strain and operating costs
