Blower Door Test in North Bergen, NJ

Verify your home’s airtightness and meet energy-efficiency standards with a professional blower door test in North Bergen, NJ. Our experts help homeowners, builders, and contractors pinpoint air leaks, improve efficiency, and comply with NJ building energy standards.

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. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. 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 North Bergen, NJ identifies air leakage issues before they become serious, ensuring efficiency, comfort, and long-term durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in North Bergen, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.

What Is A Passing Blower Door Test Score?

Homes built in North Bergen, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. When your blower door test in North Bergen, NJ meets this requirement, you ensure energy efficiency and maintain compliance with building codes.

How To Pass 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.
Apply the correct R-value insulation and verify that it’s properly fitted to seal the whole 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 any gaps connecting conditioned and unconditioned spaces, such as those leading to basements, attics, or crawl spaces.
Local authorities often publish checklists to confirm compliance — get the Philadelphia example here.
Our team at Local Energy Audits employs thermal imaging, caulk, and spray foam to locate and repair leaks efficiently on-site./li>

Preparing for a Blower Door Test in North Bergen, NJ

Preparation for blower door test in North Bergen, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. 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 all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected 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. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in North Bergen, NJ.
