Blower Door Test in River Vale, NJ

Improve insulation performance and meet energy code requirements through thorough blower door test in River Vale, NJ. Our certified technicians provide homeowners, builders, and contractors with expert air leak detection, better comfort, and complete NJ energy code compliance.

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 frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. When there are too many air leaks, drafts and discomfort can occur, along with moisture problems such as mold and condensation. A blower door test in River Vale, NJ identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in River Vale, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

What Is A Passing Blower Door Test Score?

Homes in River Vale, NJ are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. In most jurisdictions, 3 air changes per hour or less is the benchmark for acceptable blower door test results and energy efficiency. Satisfying this requirement in your blower door test in River Vale, NJ helps optimize energy use and ensures you meet local building standards.

Why Do I Need A Blower Door Test?

In NJ, both state and local jurisdictions follow the IECC (International Energy Conservation Code), requiring blower door test for new and remodeled homes. We often collaborate with home builders, contractors, and homeowners who require blower door test in River Vale, NJ to meet energy efficiency standards and close permits. A duct leakage test could be required when air ducts or HVAC units extend outside the structure’s thermal envelope. Learn more about energy code compliance.

With blower door test in River Vale, NJ, homeowners can pinpoint hidden air leaks. The depressurization process makes them obvious, enabling better sealing and lower energy costs. Typically completed within a few hours, a blower door test provides a long-lasting impact on comfort, energy efficiency, and overall home performance in NJ’ varied climate.

How To Pass A Blower Door Test:

  • Anticipate potential air leaks before testing begins.
  • Use Tyvek or Zip Sheathing as your air barrier and carefully tape all seams to prevent air leakage.
  • Use insulation that has the designated R-value and confirm it’s properly applied throughout the building envelope for maximum efficiency.
  • 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.
  • Building departments typically release step-by-step compliance lists — download the Philadelphia sample here as an example.
  • Local Energy Audits identifies and repairs leaks on-site using thermal imaging tools, caulk, and high-quality spray foam./li>
  • Over 90% of the time, we complete testing with a passing score in two hours or less and handle all permit paperwork on-site.

Preparing for a Blower Door Test in River Vale, NJ

Before starting blower door test in River Vale, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. 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 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 pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in River Vale, NJ.

Blower Door Test for Contractors in River Vale, NJ

For contractors booking blower door test in River Vale, NJ, homes with quality insulation usually require only quick, on-site fixes during testing.
