What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Lower, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

What Is A Passing Blower Door Test Score?

Properties in Lower, NJ must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. 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 Lower, NJ lowers utility bills and guarantees adherence to local code requirements.

Why Do I Need A Blower Door Test?

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Choose Tyvek or Zip Sheathing as your air barrier and check that all seams are securely taped to maintain airtightness.
Ensure the insulation used meets the proper R-value and is well fitted throughout the structure’s building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Ensure all penetrations between conditioned and unconditioned areas—like attics, basements, and crawl spaces—are tightly sealed.
Local code offices often issue compliance checklists — access the Philadelphia example here for reference.
Local Energy Audits uses professional-grade thermal imaging, caulk, and spray foam to locate and close leaks during the visit./li>

Preparing for a Blower Door Test in Lower, NJ

To properly prepare for blower door test in Lower, NJ, the HVAC system and all bathroom and kitchen fans are turned off. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond the thermal envelope. After ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. After all leaks are sealed, we retest immediately to confirm the desired blower door score has been met and that your home satisfies efficiency requirements in Lower, NJ.
