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. 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. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in West Wildwood, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in West Wildwood, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the NJ climate.

What Is A Passing Blower Door Test Score?

In West Wildwood, NJ, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Meeting this requirement during your blower door test in West Wildwood, NJ helps reduce energy costs while keeping your home compliant with local building codes.

Preparing for a Blower Door Test in West Wildwood, NJ

For blower door test in West Wildwood, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. We follow with a quick walkthrough to ensure all exterior doors and windows are fully closed — including those that connect to garages, basements, or any part 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. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in West Wildwood, NJ.
