What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Berlin borough, 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?

When blower door test in Berlin borough, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

Preparing for a Blower Door Test in Berlin borough, NJ

Preparation for blower door test in Berlin borough, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve 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 the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Berlin borough, NJ.
