What Is A Blower Door Test?

A blower door test measures how many air changes per hour occur in your home, ensuring fresh air circulation and improved indoor air quality. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in Morris, 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?

When conducting blower door test in Morris, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. 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 expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the NJ environment.

What Is A Passing Blower Door Test Score?

Houses in Morris, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Satisfying this requirement in your blower door test in Morris, NJ helps optimize energy use and ensures you meet local building standards.

Why Do I Need A Blower Door Test?

NJ state regulations and many municipalities abide by the IECC, enforcing blower door tests for newly constructed or renovated homes. We work closely with home builders, contractors, and homeowners who need blower door test in Morris, NJ to ensure compliance and successful project completion.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Close and seal every opening between heated or cooled spaces and unconditioned areas such as basements, attics, and crawl spaces.

Preparing for a Blower Door Test in Morris, NJ

Getting ready for blower door test in Morris, NJ involves turning off all heating, cooling, and exhaust ventilation systems. 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. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. 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. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Morris, NJ.
