What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Harrison township (Gloucester), NJ finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Harrison township (Gloucester), NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior 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?

Homeowners gain major advantages from blower door test in Harrison township (Gloucester), 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 air barrier like Tyvek or Zip Sheathing, making sure all connecting seams are properly taped and sealed.
  • 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.
  • Seal cracks and openings between conditioned interiors and unconditioned areas such as crawl spaces, attics, and basements.
  • Local building departments often supply a detailed checklist to ensure compliance — you can download the Philadelphia example here for guidance.
  • Local Energy Audits identifies and repairs leaks on-site using thermal imaging tools, caulk, and high-quality spray foam./li>
  • Typically, over 90% of the time we record a passing score in two hours and handle all permit-related documentation.

Preparing for a Blower Door Test in Harrison township (Gloucester), NJ

Getting ready for blower door test in Harrison township (Gloucester), NJ involves turning off all heating, cooling, and exhaust ventilation systems. 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. After ensuring the home is airtight, we install the blower door frame and fan in a central exterior door and depressurize the house to 50 Pascals to record airflow and leakage data accurately. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Harrison township (Gloucester), NJ.
