What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. Too many air changes, however, can be detrimental because every time the air is replaced, it must be reheated or recooled, leading to higher energy use and lower efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Clark, 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?

During blower door test in Clark, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. 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?

Homes in Clark, NJ are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. An acceptable blower door test result in most areas is 3 air changes per hour or less, demonstrating solid energy performance. Complying with this benchmark during a blower door test in Clark, NJ helps cut energy expenses and meet local building regulations.

Preparing for a Blower Door Test in Clark, NJ

We start the process of blower door test in Clark, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces 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. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near unconditioned spaces. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. Once sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Clark, NJ.
