What Is A Blower Door Test?

A blower door test checks the number of air changes per hour in your home, ensuring old air is replaced with new, clean air for a healthier environment. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Cinnaminson, NJ helps uncover these issues early, enabling homeowners and builders to detect air leaks, enhance energy efficiency, and ensure a more comfortable, long-lasting home.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Cinnaminson, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

What Is A Passing Blower Door Test Score?

In Cinnaminson, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Reaching the target during your blower door test in Cinnaminson, NJ guarantees lower energy consumption and full code compliance.

There are many benefits of blower door test in Cinnaminson, NJ for homeowners. When the fan lowers indoor pressure, leaks become visible, allowing for easy identification of inefficiencies and energy-saving opportunities. It only takes a few hours to perform a blower door test, but the long-lasting impact on comfort and efficiency is felt through NJ’ hot summers and cool winters.

Choose Tyvek or Zip Sheathing as your air barrier and check that all seams are securely taped to maintain airtightness.
Install insulation with the appropriate R-value and ensure it is correctly fitted across the entire building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal off any access points or gaps between conditioned and unconditioned spaces like attics, crawl spaces, and basements.

Preparing for a Blower Door Test in Cinnaminson, NJ

To ensure accuracy during blower door test in Cinnaminson, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond 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. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. After all leaks are sealed, we retest immediately to confirm the desired blower door score has been met and that your home satisfies efficiency requirements in Cinnaminson, NJ.
