What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Magnolia, NJ detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Magnolia, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in NJ.

What Is A Passing Blower Door Test Score?

In Magnolia, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Satisfying this requirement in your blower door test in Magnolia, NJ helps optimize energy use and ensures you meet local building standards.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal gaps and openings separating conditioned spaces from unconditioned areas, including crawl spaces, basements, and attics.

Preparing for a Blower Door Test in Magnolia, NJ

We start the process of blower door test in Magnolia, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area outside the thermal envelope. Once preparation is complete, the blower door fan and frame are installed in a centrally located exterior door. The fan then reduces pressure to 50 Pascals, allowing accurate leakage assessment. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. 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 Magnolia, NJ.
