What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. Too many air changes, however, can be detrimental because every time the air is replaced, it must be reheated or recooled, leading to higher energy use and lower efficiency. Too many air changes can result in drafts and leaks that create discomfort and lead to moisture, mold, and condensation issues. A blower door test in Emmaus, PA identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Emmaus, PA, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in PA climates.

What Is A Passing Blower Door Test Score?

In Emmaus, PA, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. Generally, a blower door test result of 3 air changes per hour or less is considered acceptable, ensuring proper energy performance. Meeting this requirement during your blower door test in Emmaus, PA helps reduce energy costs while keeping your home compliant with local building codes.

Why Do I Need A Blower Door Test?

Preparing for a Blower Door Test in Emmaus, PA

To prepare a home for blower door test in Emmaus, PA, we shut off the HVAC system and disable all exhaust fans. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond the thermal envelope. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Emmaus, PA.
