What Is A Blower Door Test?

A blower door test is performed to identify the rate of air changes per hour, confirming your home receives a healthy exchange of fresh air. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing 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 Estell Manor, NJ helps spot air leaks before they worsen, improving efficiency, comfort, and long-term structural quality.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Estell Manor, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

What Is A Passing Blower Door Test Score?

In Estell Manor, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Meeting this requirement during your blower door test in Estell Manor, NJ helps reduce energy costs while keeping your home compliant with local building codes.

Preparing for a Blower Door Test in Estell Manor, NJ

To prepare for blower door test in Estell Manor, NJ, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces outside the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to 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 sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Estell Manor, NJ.
