Make sure your home meets airtightness and efficiency goals with certified blower door test in Lower, NJ. Our experts help homeowners, builders, and contractors pinpoint air leaks, improve efficiency, and comply with NJ building energy standards.

What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Lower, NJ helps uncover these issues early, enabling homeowners and builders to detect air leaks, enhance energy efficiency, and ensure a more comfortable, long-lasting home.

What Our Clients Say

How Is A Blower Door Test Conducted?

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

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. 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?

Houses in Lower, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. Generally, a blower door test result of 3 air changes per hour or less is considered acceptable, ensuring proper energy performance. Achieving this goal during your blower door test in Lower, NJ promotes energy savings and demonstrates adherence to local building rules.

Preparing for a Blower Door Test in Lower, NJ

To prepare a home for blower door test in Lower, NJ, we shut off the HVAC system and disable all exhaust fans. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining the thermal envelope. After ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. 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. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Lower, NJ.
