What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in Gloucester, 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?

For accurate blower door test in Gloucester, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. 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 Gloucester, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Achieving compliance in your blower door test in Gloucester, NJ helps improve energy efficiency and meet all local code mandates.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Close and seal every opening between heated or cooled spaces and unconditioned areas such as basements, attics, and crawl spaces.

Preparing for a Blower Door Test in Gloucester, NJ

To properly prepare for blower door test in Gloucester, NJ, the HVAC system and all bathroom and kitchen fans are turned off. We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to unconditioned 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 the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. 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 Gloucester, NJ.
