What Is A Blower Door Test?

A blower door test measures how many air changes per hour occur in your home, ensuring fresh air circulation and improved indoor air quality. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Too many air changes can result in drafts and leaks that create discomfort and lead to moisture, mold, and condensation issues. A blower door test in East Windsor, NJ locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in East Windsor, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. 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 the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.

What Is A Passing Blower Door Test Score?

Residential buildings in East Windsor, NJ must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. 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 East Windsor, NJ helps reduce energy costs while keeping your home compliant with local building codes.

Preparing for a Blower Door Test in East Windsor, NJ

We start the process of blower door test in East Windsor, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. We then perform a detailed walkthrough to verify that all exterior windows and doors are tightly shut, including any that lead to spaces beyond the thermal envelope. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. 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. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting East Windsor, NJ energy code requirements.
