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. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. Excessive air changes often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in Ridgefield, NJ finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Ridgefield, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

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. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

What Is A Passing Blower Door Test Score?

Properties in Ridgefield, NJ must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Meeting this level during your blower door test in Ridgefield, NJ supports energy efficiency and verifies that your home meets local codes.

Preparing for a Blower Door Test in Ridgefield, NJ

Before conducting blower door test in Ridgefield, NJ, we make sure all heating, cooling, and ventilation fans are switched off. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Ridgefield, NJ.
