What Is A Blower Door Test?

A blower door test measures how many air changes per hour occur in your home, ensuring fresh air circulation and improved indoor air quality. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Roseland, 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 execute blower door test in Roseland, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

What Is A Passing Blower Door Test Score?

In Roseland, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. 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. Passing this requirement during a blower door test in Roseland, NJ keeps your home efficient and aligned with local building code standards.

  • Install a quality air barrier like Tyvek or Zip Sheathing and confirm that all joints and seams are completely taped.
  • Install insulation of the appropriate R-value and inspect to confirm it’s correctly fitted in all envelope areas.
  • 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.
  • Building departments typically release step-by-step compliance lists — download the Philadelphia sample here as an example.
  • Using thermal imaging technology along with caulk and spray foam, Local Energy Audits identifies and seals leaks during the inspection./li>

Preparing for a Blower Door Test in Roseland, NJ

To prepare a home for blower door test in Roseland, NJ, we shut off the HVAC system and disable all exhaust fans. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Roseland, NJ.
