Blower Door Test 

Have you noticed any of the following in your home?

  • Drafty rooms
  • Excessive dust
  • Outside noises are heard in your home
  • High utility bills

Imagine having a window in your house that never closes. By conducting the blower door test, we measure your home’s air leaks and determine the size of this “window”. We calculate the Building Airflow Standard for the size of your home and occupancy rate, and compare that to what the actual blower door results tell us in Cubic Feet per Minute (CFM).  We can tell you how much energy you are wasting due to excess air-flow, and what our limit is for making your home air tight while maintaining healthy air.

How do we do it?

Blower Door test is a professional tool to help determine the air infiltration rate of a building. Blower doors consist of a frame and flexible panel that fit in a doorway, a variable-speed fan, a pressure gauge to measure the pressure differences inside and outside the home, and an airflow manometer and hoses for measuring airflow. Once we get the output we can design adjustments for your home and you can save more money on energy bills!

Blower door tests are for new construction and/or major renovations - It is required for Occupancy Permits.
