What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Upper, NJ assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Upper, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.

What Is A Passing Blower Door Test Score?

In Upper, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. Generally, a blower door test result of 3 air changes per hour or less is considered acceptable, ensuring proper energy performance. Meeting this benchmark in your blower door test in Upper, NJ reduces ongoing energy costs while ensuring local regulatory compliance.

Why Do I Need A Blower Door Test?

The State of NJ and local municipalities have implemented the IECC code, which mandates blower door test on new and remodeled residential homes. We often collaborate with home builders, contractors, and homeowners who require blower door test in Upper, NJ to meet energy efficiency standards and close permits. A duct leakage test may also be necessary if any ducts or HVAC systems are positioned outside the building’s thermal envelope. Learn more about energy code compliance.

By performing blower door test in Upper, NJ, homeowners can identify where conditioned air escapes. Depressurization makes leaks visible, uncovering ways to enhance comfort and efficiency. 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.
Choose Tyvek or Zip Sheathing as your air barrier and check that all seams are securely taped to maintain airtightness.
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 and seal every opening between heated or cooled spaces and unconditioned areas such as basements, attics, and crawl spaces.
Local code offices often issue compliance checklists — access the Philadelphia example here for reference.
With the help of thermal imaging tools, caulk, and spray foam, Local Energy Audits efficiently detects and seals leaks on-site./li>
Over 90% of our projects pass within two hours, with all required paperwork issued immediately to close the permit.

Preparing for a Blower Door Test in Upper, NJ

Before starting blower door test in Upper, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to unconditioned 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 house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Upper, NJ.

Blower Door Test for Contractors in Upper, NJ

For contractors conducting blower door test in Upper, NJ, well-insulated homes generally require only minimal on-site corrections during the test. With materials such as chalk and spray foam, most small leaks or gaps can be sealed immediately on-site. In more than 90% of cases, we achieve a passing blower door test score within two hours and provide complete documentation to close out the building permit the same day.
