What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Mansfield township, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Mansfield township, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. In most jurisdictions, 3 air changes per hour or less is the benchmark for acceptable blower door test results and energy efficiency. When your blower door test in Mansfield township, NJ meets this requirement, you ensure energy efficiency and maintain compliance with building codes.

Preparing for a Blower Door Test in Mansfield township, NJ

Before starting blower door test in Mansfield township, 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. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Mansfield township, NJ energy code requirements.
