What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Wallington, NJ finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Wallington, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. 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 air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

What Is A Passing Blower Door Test Score?

Houses in Wallington, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version.

Preparing for a Blower Door Test in Wallington, NJ

Preparation for blower door test in Wallington, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve 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 depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. 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. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Wallington, NJ building codes.
