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. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Fairview, NJ enables early identification of air leaks, helping improve comfort, durability, and energy savings.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Fairview, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. 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 the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. 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?

In Fairview, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. Meeting this requirement during your blower door test in Fairview, NJ helps reduce energy costs while keeping your home compliant with local building codes.

Why Do I Need A Blower Door Test?

The State of NJ, together with many cities and counties, enforces the IECC (International Energy Conservation Code), which calls for blower door test on new or renovated residential properties.

There are many benefits of blower door test in Fairview, NJ for homeowners. When the fan lowers indoor pressure, leaks become visible, allowing for easy identification of inefficiencies and energy-saving opportunities. A short blower door test can result in a long-lasting impact on your home’s energy efficiency, comfort, and year-round performance in NJ.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Select a proper air barrier such as Tyvek or Zip Sheathing and ensure every seam is thoroughly taped for airtight sealing.
Use insulation of the correct R-value and confirm that it’s tightly installed throughout every section of the 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 permitting offices often offer official compliance checklists — review the Philadelphia sample here for reference.
Using thermal imaging technology along with caulk and spray foam, Local Energy Audits identifies and seals leaks during the inspection./li>

Preparing for a Blower Door Test in Fairview, NJ

To get ready for blower door test in Fairview, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to unconditioned spaces 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 the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. 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 Fairview, NJ.
