What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Bellmawr borough, NJ allows early detection of air leaks, helping homeowners and builders boost efficiency and maintain a comfortable, durable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Bellmawr borough, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Homes throughout Bellmawr borough, NJ are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. 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 goal during your blower door test in Bellmawr borough, NJ promotes energy savings and demonstrates adherence to local building rules.

Preparing for a Blower Door Test in Bellmawr borough, NJ

Before starting blower door test in Bellmawr borough, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements outside the thermal envelope. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and 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 technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Bellmawr borough, NJ energy standards.
