Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. Excessive air changes can also lead to drafts and discomfort caused by air leaks, along with moisture, condensation, and mold problems inside the home.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Readington, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in NJ.

What Is A Passing Blower Door Test Score?

In Readington, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. Generally, a blower door test result of 3 air changes per hour or less is considered acceptable, ensuring proper energy performance. Complying with this benchmark during a blower door test in Readington, NJ helps cut energy expenses and meet local building regulations.

Preparing for a Blower Door Test in Readington, NJ

For blower door test in Readington, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces outside the thermal envelope. Once everything is sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Readington, NJ.
