Blower Door Test in Berkeley Heights, NJ

Enhance comfort and confirm compliance with detailed blower door test in Berkeley Heights, NJ. Our skilled technicians help homeowners, builders, and contractors find air leaks, increase comfort, and comply with NJ energy standards.

What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Berkeley Heights, NJ helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

To perform blower door test in Berkeley Heights, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.

What Is A Passing Blower Door Test Score?

Homes in Berkeley Heights, NJ are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent 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. Reaching this target in your blower door test in Berkeley Heights, NJ helps maintain lower energy bills and fulfills local code obligations.

Why Do I Need A Blower Door Test?

Following the IECC guidelines, NJ and many local jurisdictions require blower door test on newly built or renovated residential dwellings. We proudly serve home builders, contractors, and homeowners who need blower door test in Berkeley Heights, NJ to pass inspections and fulfill energy code obligations. 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.

Homeowners who choose blower door test in Berkeley Heights, NJ can easily locate leaks. As the fan depressurizes the home, airflow through gaps becomes apparent, exposing areas needing improvement. Although it’s a short process, a blower door test produces a long-lasting impact by improving comfort and lowering energy costs throughout NJ’ climate extremes.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Apply an appropriate air barrier, such as Tyvek or Zip Sheathing, making sure every seam is correctly taped for maximum performance.
Use insulation with the right R-value and confirm it is properly installed throughout 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.
Make sure to seal all separations between conditioned and unconditioned areas, including crawl spaces, basements, and attics.
Many local building offices offer a step-by-step checklist to confirm compliance — view the Philadelphia sample here.
Local Energy Audits technicians carry thermal imaging devices, caulk, and spray foam to pinpoint and seal air leaks immediately./li>

Preparing for a Blower Door Test in Berkeley Heights, NJ

Preparation for blower door test in Berkeley Heights, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. 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. 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. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint 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. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. Once sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Berkeley Heights, NJ.

Blower Door Test for Contractors in Berkeley Heights, NJ

For contractors arranging blower door test in Berkeley Heights, NJ, most homes with professional insulation can handle small air leakage issues during the test itself. With materials such as chalk and spray foam on hand, minor leaks or gaps can usually be sealed immediately. In over 90% of cases, we are able to reach a passing blower door test score in under two hours and supply all necessary paperwork to finalize the building permit right away.
