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. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors.

What Our Clients Say

How Is A Blower Door Test Conducted?

For blower door test in Manchester, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in NJ.

What Is A Passing Blower Door Test Score?

Preparing for a Blower Door Test in Manchester, NJ

When preparing for blower door test in Manchester, NJ, we first switch off the home’s heating, cooling, and exhaust systems. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond 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 occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Manchester, NJ efficiency standards.
