What Is A Blower Door Test?

A blower door test is performed to identify the rate of air changes per hour, confirming your home receives a healthy exchange of fresh air. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Morris township, NJ identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Morris township, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. 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 Morris township, NJ, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Satisfying this requirement in your blower door test in Morris township, NJ helps optimize energy use and ensures you meet local building standards.

Preparing for a Blower Door Test in Morris township, NJ

Getting ready for blower door test in Morris township, NJ involves turning off all heating, cooling, and exhaust ventilation systems. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside the thermal envelope. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. 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 the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Morris township, NJ energy code requirements.
