Blower Door Test in Old Bridge, NJ

Assess your home’s air sealing and energy standards with trusted blower door test in Old Bridge, NJ. Our certified team partners with homeowners, builders, and contractors to uncover air leaks, enhance comfort, and ensure NJ energy code adherence.

What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. 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. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Old Bridge, NJ locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Old Bridge, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. 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?

In Old Bridge, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Meeting this level during your blower door test in Old Bridge, NJ supports energy efficiency and verifies that your home meets local codes.

Preparing for a Blower Door Test in Old Bridge, NJ

For blower door test in Old Bridge, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements outside the thermal envelope. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Old Bridge, NJ building codes.
