What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Linwood, 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?

When performing blower door test in Linwood, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. 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?

Properties in Linwood, NJ must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency.

Preparing for a Blower Door Test in Linwood, NJ

We begin blower door test in Linwood, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. 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 properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. Our team brings chalk, spray foam, and weatherstripping supplies to every job, enabling us to collaborate with homeowners or contractors to seal visible air leakage areas immediately. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Linwood, NJ efficiency standards.
