What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. Too many air changes, however, can be detrimental because every time the air is replaced, it must be reheated or recooled, leading to higher energy use and lower efficiency. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Summit, NJ helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Summit, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

What Is A Passing Blower Door Test Score?

Homes built in Summit, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. In most areas, an acceptable blower door test result is 3 air changes per hour or less, confirming that the home achieves optimal energy efficiency. Meeting this level during your blower door test in Summit, NJ supports energy efficiency and verifies that your home meets local codes.

Preparing for a Blower Door Test in Summit, NJ

When preparing for blower door test in Summit, NJ, we first switch off the home’s heating, cooling, and exhaust 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. Once preparation is complete, the blower door fan and frame are installed in a centrally located exterior door. The fan then reduces pressure to 50 Pascals, allowing accurate leakage assessment. 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 bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. Once sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Summit, NJ.

Blower Door Test for Contractors in Summit, NJ

Most professionally insulated homes undergoing blower door test in Summit, NJ can resolve small issues on-site during the contractor’s visit.
