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. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall 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 Lacey township, NJ assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Lacey township, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. 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 extracts air, exterior air begins entering the house through any unsealed spaces or cracks. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in NJ.

What Is A Passing Blower Door Test Score?

In Lacey township, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Complying with this benchmark during a blower door test in Lacey township, NJ helps cut energy expenses and meet local building regulations.

Why Do I Need A Blower Door Test?

Both NJ and local jurisdictions adopt the IECC energy code, making blower door test mandatory for new and renovated residential structures. Our professionals frequently support home builders, contractors, and homeowners who need blower door test in Lacey township, NJ to comply with energy codes and finalize projects.

Preparing for a Blower Door Test in Lacey township, NJ

We begin blower door test in Lacey township, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and 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 sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Lacey township, NJ.
