What Is A Blower Door Test?

A blower door test is performed to identify the rate of air changes per hour, confirming your home receives a healthy exchange of fresh air. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Runnemede borough, NJ enables early identification of air leaks, helping improve comfort, durability, and energy savings.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Runnemede borough, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. 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 removes air from inside, exterior air flows in through leaks and gaps in the building envelope. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. 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?

In Runnemede borough, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. An acceptable blower door test result in most areas is 3 air changes per hour or less, demonstrating solid energy performance. Passing this requirement during a blower door test in Runnemede borough, NJ keeps your home efficient and aligned with local building code standards.

Preparing for a Blower Door Test in Runnemede borough, NJ

Before conducting blower door test in Runnemede borough, NJ, we make sure all heating, cooling, and ventilation fans are switched off. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within 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 house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Runnemede borough, NJ building codes.
