What Is A Blower Door Test?

A blower door test measures the air changes per hour within a home or building. Air exchange is a normal and healthy process that allows stale indoor air to be replaced with fresh air. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Emerson, NJ helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

For blower door test in Emerson, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.

What Is A Passing Blower Door Test Score?

Houses in Emerson, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Complying with this benchmark during a blower door test in Emerson, NJ helps cut energy expenses and meet local building regulations.

Preparing for a Blower Door Test in Emerson, NJ

To get ready for blower door test in Emerson, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces outside the thermal envelope. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Emerson, NJ.
