What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Westdeptford township, 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?

While performing blower door test in Westdeptford township, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. 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. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the NJ environment.

What Is A Passing Blower Door Test Score?

Residential buildings in Westdeptford township, NJ must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Satisfying this requirement in your blower door test in Westdeptford township, NJ helps optimize energy use and ensures you meet local building standards.

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.
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 Westdeptford township, NJ

Before conducting blower door test in Westdeptford township, NJ, we make sure all heating, cooling, and ventilation fans are switched off. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond the thermal envelope. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Westdeptford township, NJ energy standards.
