What Is A Blower Door Test?

A blower door test checks the number of air changes per hour in your home, ensuring old air is replaced with new, clean air for a healthier environment. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Highland Park, NJ assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Highland Park, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. 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?

Homes built in Highland Park, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Achieving this goal during your blower door test in Highland Park, NJ promotes energy savings and demonstrates adherence to local building rules.

Preparing for a Blower Door Test in Highland Park, NJ

To properly prepare for blower door test in Highland Park, NJ, the HVAC system and all bathroom and kitchen fans are turned off. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Highland Park, NJ.
