Blower Door Test in Hackensack, NJ

Confirm your home’s energy performance and identify leaks through accurate blower door test in Hackensack, NJ. Our trained team assists homeowners, builders, and contractors by detecting hidden air leaks, boosting comfort, and meeting NJ energy regulations.

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. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. 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 Hackensack, NJ finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Hackensack, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Construction in Hackensack, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Passing this threshold during your blower door test in Hackensack, NJ ensures both energy savings and full compliance with local regulations.

Preparing for a Blower Door Test in Hackensack, NJ

We begin blower door test in Hackensack, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. 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. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected 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. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Hackensack, NJ building codes.
