What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Too many air changes, however, can be detrimental because every time the air is replaced, it must be reheated or recooled, leading to higher energy use and lower efficiency. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in Mount Ephraim, 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 carry out blower door test in Mount Ephraim, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.

What Is A Passing Blower Door Test Score?

In Mount Ephraim, 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. Meeting this level during your blower door test in Mount Ephraim, NJ supports energy efficiency and verifies that your home meets local codes.

Preparing for a Blower Door Test in Mount Ephraim, NJ

For blower door test in Mount Ephraim, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. 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. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. 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’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. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Mount Ephraim, NJ efficiency codes.
