What Is A Blower Door Test?

A blower door test measures the air changes per hour within a home or building. Air exchange is a normal and healthy process that allows stale indoor air to be replaced with fresh air. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. Excessive air changes can also lead to drafts and discomfort caused by air leaks, along with moisture, condensation, and mold problems inside the home. A blower door test in Saddle Brook, NJ helps uncover these issues early, enabling homeowners and builders to detect air leaks, enhance energy efficiency, and ensure a more comfortable, long-lasting home.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Saddle Brook, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under NJ conditions.

What Is A Passing Blower Door Test Score?

In Saddle Brook, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Achieving this standard in your blower door test in Saddle Brook, NJ lowers utility bills and guarantees adherence to local code requirements.

Preparing for a Blower Door Test in Saddle Brook, NJ

To get ready for blower door test in Saddle Brook, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to unconditioned spaces outside 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. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Saddle Brook, NJ energy efficiency codes.
