What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in North Haledon, 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?

Before blower door test in North Haledon, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under NJ conditions.

What Is A Passing Blower Door Test Score?

Homes throughout North Haledon, NJ are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Complying with this benchmark during a blower door test in North Haledon, NJ helps cut energy expenses and meet local building regulations.

Preparing for a Blower Door Test in North Haledon, NJ

For blower door test in North Haledon, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen 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. 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 depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. 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. Our team brings chalk, spray foam, and weatherstripping supplies to every job, enabling us to collaborate with homeowners or contractors to seal visible air leakage areas immediately. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in North Haledon, NJ.
