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. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. 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 Woodbury Heights, 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 Woodbury Heights, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. 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.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. 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?

In Woodbury Heights, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. Generally, a blower door test result of 3 air changes per hour or less is considered acceptable, ensuring proper energy performance. Satisfying this requirement in your blower door test in Woodbury Heights, NJ helps optimize energy use and ensures you meet local building standards.

Why Do I Need A Blower Door Test?

Anticipate potential air leaks before testing begins.
Apply an effective air barrier such as Tyvek or Zip Sheathing, ensuring every seam is tightly sealed with proper tape.
Install insulation that meets the required R-value and check that it’s evenly and securely placed throughout the building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Properly seal all connections between conditioned and unconditioned zones, including basements, crawl spaces, and attics.

Preparing for a Blower Door Test in Woodbury Heights, NJ

To ensure accuracy during blower door test in Woodbury Heights, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. 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, 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 the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. 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 Woodbury Heights, NJ.
