What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in Lindenwold, NJ locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Lindenwold, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. 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?

Houses in Lindenwold, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. An acceptable blower door test result in most areas is 3 air changes per hour or less, demonstrating solid energy performance. Reaching the target during your blower door test in Lindenwold, NJ guarantees lower energy consumption and full code compliance.

Preparing for a Blower Door Test in Lindenwold, NJ

To prepare a home for blower door test in Lindenwold, NJ, we shut off the HVAC system and disable all exhaust fans. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining the thermal envelope. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Lindenwold, NJ energy code requirements.
