What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Galloway, NJ assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Galloway, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. 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.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

What Is A Passing Blower Door Test Score?

Homes throughout Galloway, NJ are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Complying with this benchmark during a blower door test in Galloway, NJ helps cut energy expenses and meet local building regulations.

Preparing for a Blower Door Test in Galloway, NJ

We begin blower door test in Galloway, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces outside the thermal envelope. After ensuring the home is airtight, we install the blower door frame and fan in a central exterior door and depressurize the house to 50 Pascals to record airflow and leakage data accurately. 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 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 work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Galloway, NJ.
