What Is A Blower Door Test?

A blower door test checks the number of air changes per hour in your home, ensuring old air is replaced with new, clean air for a healthier environment. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Little Falls, NJ detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

To perform blower door test in Little Falls, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. 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?

Residential buildings in Little Falls, NJ must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations.

Preparing for a Blower Door Test in Little Falls, NJ

To prepare a home for blower door test in Little Falls, NJ, we shut off the HVAC system and disable all exhaust fans. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond the thermal envelope. 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. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. 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. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Little Falls, NJ building codes.
