What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. 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 Deptford, NJ helps spot air leaks before they worsen, improving efficiency, comfort, and long-term structural quality.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Deptford, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

What Is A Passing Blower Door Test Score?

Homes in Deptford, NJ are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Achieving compliance in your blower door test in Deptford, NJ helps improve energy efficiency and meet all local code mandates.

Preparing for a Blower Door Test in Deptford, NJ

Before conducting blower door test in Deptford, NJ, we make sure all heating, cooling, and ventilation fans are switched off. 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. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Deptford, NJ.
