What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. 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 Burlington city, NJ helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Burlington city, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under NJ conditions.

What Is A Passing Blower Door Test Score?

In Burlington city, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. In most areas, an acceptable blower door test result is 3 air changes per hour or less, confirming that the home achieves optimal energy efficiency. Meeting this benchmark in your blower door test in Burlington city, NJ reduces ongoing energy costs while ensuring local regulatory compliance.

Why Do I Need A Blower Door Test?

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Use a reliable air barrier like Tyvek or Zip Sheathing and make sure all seams are securely taped.
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.
Ensure all penetrations between conditioned and unconditioned areas—like attics, basements, and crawl spaces—are tightly sealed.
Local building departments often supply a detailed checklist to ensure compliance — you can download the Philadelphia example here for guidance.
Local Energy Audits technicians carry thermal imaging devices, caulk, and spray foam to pinpoint and seal air leaks immediately./li>

Preparing for a Blower Door Test in Burlington city, NJ

When preparing for blower door test in Burlington city, NJ, we first switch off the home’s heating, cooling, and exhaust systems. We then perform a detailed walkthrough to verify that all exterior windows and doors are tightly shut, including any that lead to spaces beyond the thermal envelope. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Burlington city, NJ.
