What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in West Milford, NJ identifies air leakage issues before they become serious, ensuring efficiency, comfort, and long-term durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in West Milford, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

What Is A Passing Blower Door Test Score?

In West Milford, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. By meeting this standard in your blower door test in West Milford, NJ, you can enjoy lower utility bills and peace of mind with code compliance.

Our team frequently assists home builders, contractors, and homeowners performing blower door test in West Milford, NJ to verify compliance and secure permit approval. A duct leakage test is sometimes required if any HVAC components or duct lines are found beyond the building’s thermal envelope. Learn more about energy code compliance.

A blower door test in West Milford, NJ helps homeowners discover inefficiencies. Depressurizing the home makes leaks more noticeable and highlights where energy can be conserved. Typically completed within a few hours, a blower door test provides a long-lasting impact on comfort, energy efficiency, and overall home performance in NJ’ varied climate.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Apply an effective air barrier such as Tyvek or Zip Sheathing, ensuring every seam is tightly sealed with proper tape.
Use insulation that has the designated R-value and confirm it’s properly applied throughout the building envelope for maximum efficiency.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal off any access points or gaps between conditioned and unconditioned spaces like attics, crawl spaces, and basements.
Local permitting offices often offer official compliance checklists — review the Philadelphia sample here for reference.
Local Energy Audits uses thermal imaging tools, caulk, and spray foam to detect and seal leaks directly on-site./li>
In most situations—over 90% of the time—we get a passing score within two hours and finalize all required paperwork.

Preparing for a Blower Door Test in West Milford, NJ

Getting ready for blower door test in West Milford, NJ involves turning off all heating, cooling, and exhaust ventilation systems. 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. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to 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 leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in West Milford, NJ.
