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. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. 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 Kearny, NJ helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Kearny, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

What Is A Passing Blower Door Test Score?

Houses in Kearny, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing.

Preparing for a Blower Door Test in Kearny, NJ

To prepare for blower door test in Kearny, NJ, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. We follow with a quick walkthrough to ensure all exterior doors and windows are fully closed — including those that connect to garages, basements, or any part 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. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. 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 Kearny, NJ.
