Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Weymouth township, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Construction in Weymouth township, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities.

Preparing for a Blower Door Test in Weymouth township, NJ

Preparation for blower door test in Weymouth township, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. 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. After ensuring the home is airtight, we install the blower door frame and fan in a central exterior door and depressurize the house to 50 Pascals to record airflow and leakage data accurately. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Weymouth township, NJ energy code requirements.
