What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Laurel Springs borough, NJ detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Laurel Springs borough, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. 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?

Homes in Laurel Springs borough, NJ are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally.

Preparing for a Blower Door Test in Laurel Springs borough, NJ

To ensure accuracy during blower door test in Laurel Springs borough, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside 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. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Laurel Springs borough, NJ energy code requirements.
