What Is A Blower Door Test?

A blower door test measures how many air changes per hour occur in your home, ensuring fresh air circulation and improved indoor air quality. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Maple Shade, NJ detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Maple Shade, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. 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.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under NJ conditions.

What Is A Passing Blower Door Test Score?

In Maple Shade, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Passing this requirement during a blower door test in Maple Shade, NJ keeps your home efficient and aligned with local building code standards.

Preparing for a Blower Door Test in Maple Shade, NJ

Before conducting blower door test in Maple Shade, NJ, we make sure all heating, cooling, and ventilation fans are switched off. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other 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. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Maple Shade, NJ building codes.
