What Is A Blower Door Test?

A blower door test measures how many air changes per hour occur in your home, ensuring fresh air circulation and improved indoor air quality. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Island Heights, NJ identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Island Heights, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Homes in Island Heights, NJ are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Meeting this requirement during your blower door test in Island Heights, NJ helps reduce energy costs while keeping your home compliant with local building codes.

Why Do I Need A Blower Door Test?

The State of NJ, along with its municipalities, observes the IECC requirements, mandating blower door test for newly constructed or updated homes.

Preparing for a Blower Door Test in Island Heights, NJ

To ensure accuracy during blower door test in Island Heights, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Island Heights, NJ.
