As part of the Blower Door Test, Momentum utilizes the Minneapolis Blower Door on-site, during the final inspection to measure the airtightness of forced air.

The Blower Door test provides a reliable, highly accurate, and cost-effective method for determining a home’s air leakage. The Blower Door test can identify building envelope leakage; leaks such as penetration from plumbing and electrical can cause drafts resulting in an unwanted variance in temperature. Blower Door airtightness measurements can help estimate the need for additional mechanical ventilation.


You are ready for a Blower Door test if:  
  • Attic insulation is installed 
  • Appliances are installed
  • Carpet, doors, & weathering stripping are in place
