Blower Door Testing in Des Moines Homes

This video shows how a blower door test is performed to test for air leakage within a home.

Find air leaks to save energy, increase comfort & improve indoor air quality

Dr. Energy Saver technicians know where to look for leaks. But to get a complete picture of how your home leaks and wastes energy, they also use specialized equipment. An infiltrometer, or blower door fan, is usually placed in the main entry door to suck inside air out.

This forces outside air into the house through leaks, doors and windows. When the fan is running a technician diagnoses air leaks in each room of the home.

How a blower door test works

Blower door test for Marshalltown homes

In a blower door test, a fan is used to create a negative pressure in your house. This causes outside air to be sucked in, making it easier to find the gaps and cracks that allow it in.

Sometimes our technicians literally see or hear where air is coming into the house. But special tools are also used to pinpoint leaks. Dr. Energy Saver's technicians may also use a camera that's sensitive to temperature differences, with possible air leaks shown in various colors.

The blower door test also gives technicians your home's air-leakage rate so you have data to quantify the air leaks. Your home energy technician can compare the leakage rate (expressed in cubic feet of air per minute) to the size of your home to see how many air changes per hour (ACH) your house may have due to air leakage. 

Blower door tests can help you determine whether or not you need to replace windows, better insulate your attic, or increase your home's energy efficiency with a better air sealing approach.
