Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in Wantage, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Wantage, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

What Is A Passing Blower Door Test Score?

In Wantage, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Meeting this level during your blower door test in Wantage, NJ supports energy efficiency and verifies that your home meets local codes.

Preparing for a Blower Door Test in Wantage, NJ

For blower door test in Wantage, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering 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. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Wantage, NJ.
