What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. 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 Barrington, NJ enables early identification of air leaks, helping improve comfort, durability, and energy savings.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Barrington, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. 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 removes air, outside air naturally flows inside through leaks, joints, and other gaps. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.

What Is A Passing Blower Door Test Score?

In Barrington, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. Meeting this benchmark in your blower door test in Barrington, NJ reduces ongoing energy costs while ensuring local regulatory compliance.

Why Do I Need A Blower Door Test?

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.

Preparing for a Blower Door Test in Barrington, NJ

To prepare a home for blower door test in Barrington, NJ, we shut off the HVAC system and disable all exhaust fans. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve the thermal envelope. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Barrington, NJ.
