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. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in South Bound Brook, NJ detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

To perform blower door test in South Bound Brook, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

What Is A Passing Blower Door Test Score?

Houses in South Bound Brook, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Passing this requirement during a blower door test in South Bound Brook, NJ keeps your home efficient and aligned with local building code standards.

Preparing for a Blower Door Test in South Bound Brook, NJ

Preparation for blower door test in South Bound Brook, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. Once everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to South Bound Brook, NJ energy efficiency codes.
