What Is A Blower Door Test?

A blower door test helps determine the air changes per hour to confirm that your home has sufficient fresh air replacement. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. Too many air changes can result in drafts and leaks that create discomfort and lead to moisture, mold, and condensation issues. A blower door test in Readington, 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 Readington, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.

Homes built in Readington, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect.

Achieving compliance in your blower door test in Readington, NJ helps improve energy efficiency and meet all local code mandates.

Preparing for a Blower Door Test in Readington, NJ

When preparing for blower door test in Readington, NJ, we first switch off the home’s heating, cooling, and exhaust systems. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces outside the thermal envelope. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and 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 sealing is complete, we perform an immediate retest to verify that the desired blower door score is achieved and that your home meets all energy efficiency requirements in Readington, NJ.
