What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. 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 also lead to drafts and discomfort caused by air leaks, along with moisture, condensation, and mold problems inside the home. A blower door test in Kearny, NJ helps spot air leaks before they worsen, improving efficiency, comfort, and long-term structural quality.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Kearny, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. 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?

Construction in Kearny, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Passing this threshold during your blower door test in Kearny, NJ ensures both energy savings and full compliance with local regulations.

Preparing for a Blower Door Test in Kearny, NJ

As part of preparing for blower door test in Kearny, NJ, we power down the HVAC system along with kitchen and bathroom exhaust fans. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond the thermal envelope. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Kearny, NJ efficiency standards.
