Blower Door Testing: Your Questions Answered

At Metro Garage Doors, we are pleased to offer free visual home energy audits. For these audits, we perform a series of tests to reveal underlying air infiltration and efficiency issues in your home.  We also offer recommendations for improvement through a detailed, prioritized plan of action.

We also offer a scientific home energy audit that includes blower door testing. What is blower door testing, and why would you need it?

What Is Blower Door Testing?

A blower door is a powerful fan that mounts into the frame of an exterior door. We install the fan and a temporary door cover inside the doorway. Then, we close all the windows in the house, open all the internal doors, and turn on the fan. The fan pulls air out of the house, lowering the air pressure inside. The higher outside air pressure then flows in through all unsealed cracks and openings. 

What Does Blower Door Testing Do?

Blower door testing allows us to quickly:

  • Determine the quantity and location of air leakage throughout your home.
  • Identify air leaks, areas of high moisture and airflow within walls.
  • Examine the interior and exterior of your home for air sealing and insulation needs.

Why Do I Need It?

According to the Energy Department, the average home has enough air leakage to add up to a two-foot-square hole. This is like leaving a medium-sized window open 24 hours a day! You wouldn’t leave a window open all day year-round, so you want to locate and seal any air leaks in your home.

As part of your scientific home energy audit, we provide you with a comprehensive home energy report that shows which energy efficiency upgrades are best for your home and your potential energy savings. Many homeowners find the testing pays for itself in lower energy bills.
