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. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall 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 Ocean township (Ocean), 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?

To perform blower door test in Ocean township (Ocean), NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Ocean township (Ocean), NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. In most jurisdictions, 3 air changes per hour or less is the benchmark for acceptable blower door test results and energy efficiency. Passing this requirement during a blower door test in Ocean township (Ocean), NJ keeps your home efficient and aligned with local building code standards.

Preparing for a Blower Door Test in Ocean township (Ocean), NJ

Preparation for blower door test in Ocean township (Ocean), NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces outside the thermal envelope. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Ocean township (Ocean), NJ.
