What Is A Blower Door Test?

A blower door test helps determine the air changes per hour to confirm that your home has sufficient fresh air replacement. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in South Toms River, 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?

During blower door test in South Toms River, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. 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?

Houses in South Toms River, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Meeting this level during your blower door test in South Toms River, NJ supports energy efficiency and verifies that your home meets local codes.

Homeowners gain major advantages from blower door test in South Toms River, NJ. As the fan depressurizes the home, incoming air through leaks becomes easier to detect, revealing problem spots and potential energy-saving improvements. A blower door test may take just a few hours, yet its long-lasting impact can greatly improve your home’s comfort and energy use across NJ’ hot summers and cool winters.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Apply an appropriate air barrier, such as Tyvek or Zip Sheathing, making sure every seam is correctly taped for maximum performance.
Install correctly rated insulation with the proper R-value and confirm it’s well positioned in every part of 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.
Close gaps and penetrations between conditioned zones and unconditioned sections like attics, basements, and crawl spaces.

Preparing for a Blower Door Test in South Toms River, NJ

To ensure accuracy during blower door test in South Toms River, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting South Toms River, NJ energy code requirements.
