What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Millburn township, NJ helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Millburn township, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Properties in Millburn township, NJ must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. Generally, a blower door test result of 3 air changes per hour or less is considered acceptable, ensuring proper energy performance.

Preparing for a Blower Door Test in Millburn township, NJ

We start the process of blower door test in Millburn township, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining the thermal envelope. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to 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 Millburn township, NJ.
