Blower Door Test

Testing for air leaks identifies problem areas in your home

Blower door

A blower door test sucks the air out of a house, drawing in outside air through leakage points.

At Dr. Energy Saver, we know where to find air leaks in your home. However, we also use some specialized equipment to get a complete picture of how your home is losing energy.

We use a blower door test to identify key problem areas in the home. This process allows us to find all the small air leaks that are causing you to lose energy and waste money, allowing us to create a custom solution plan.

How does the blower door test work?

Smoke pencil test

Smoke tools help to pinpoint air leak locations in the home.

To conduct a blower door test, an infiltrometer or blower door fan is placed in the main entry doorway to depressurize the house or suck out air from the interior. This process will cause outside air to be drawn into the house through leakage points. As the fan is running, a technician can move from room to room throughout the house to detect and diagnose air leaks.

Sometimes it's possible to literally see or hear where the air is coming into the house. We also use heatless smoke tools to pinpoint leak locations, as the smoke will be sucked out through the leakage point. Technicians may also use a special camera that's super-sensitive to differences in temperature. Surface temperatures show up in contrasting colors, indicating a possible air leakage point.

In addition to helping the technician detect and diagnose air-leaks all over the house, a blower door test also allows your home's air-leakage rate to be calculated. All of this information allows us to recommend the best options for your home moving forward.
