What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Florence, 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?

During blower door test in Florence, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. 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 precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. 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?

Houses in Florence, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test.

Preparing for a Blower Door Test in Florence, NJ

Preparation for blower door test in Florence, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. 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 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. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Florence, NJ efficiency standards.
