What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. When there are too many air leaks, drafts and discomfort can occur, along with moisture problems such as mold and condensation. A blower door test in Lacey, NJ helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Lacey, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. 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.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.

What Is A Passing Blower Door Test Score?

Residential buildings in Lacey, NJ must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Achieving compliance in your blower door test in Lacey, NJ helps improve energy efficiency and meet all local code mandates.

Preparing for a Blower Door Test in Lacey, NJ

To prepare a home for blower door test in Lacey, NJ, we shut off the HVAC system and disable all exhaust fans. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements outside the thermal envelope. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Lacey, NJ.
