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. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Cinnaminson, NJ identifies air leakage issues before they become serious, ensuring efficiency, comfort, and long-term durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Cinnaminson, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. 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 exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

What Is A Passing Blower Door Test Score?

Homes built in Cinnaminson, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect.

Preparing for a Blower Door Test in Cinnaminson, NJ

Preparation for blower door test in Cinnaminson, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces outside the thermal envelope. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. After all leaks are sealed, we retest immediately to confirm the desired blower door score has been met and that your home satisfies efficiency requirements in Cinnaminson, NJ.
