What Is A Blower Door Test?

A blower door test is performed to identify the rate of air changes per hour, confirming your home receives a healthy exchange of fresh air. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Palisades Park, NJ detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Palisades Park, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. 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.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. 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 Palisades Park, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. An acceptable blower door test result in most areas is 3 air changes per hour or less, demonstrating solid energy performance. Passing this threshold during your blower door test in Palisades Park, NJ ensures both energy savings and full compliance with local regulations.

Why Do I Need A Blower Door Test?

NJ and local city codes follow the IECC (International Energy Conservation Code), which mandates blower door tests on residential buildings after construction or renovation. We provide support to home builders, contractors, and homeowners needing blower door test in Palisades Park, NJ for meeting energy efficiency standards and finalizing permits. If any part of the HVAC system or ductwork sits beyond the building’s thermal envelope, a duct leakage test may be required. Learn more about energy code compliance.

Homeowners who choose blower door test in Palisades Park, NJ can easily locate leaks. As the fan depressurizes the home, airflow through gaps becomes apparent, exposing areas needing improvement. A blower door test usually takes just a few hours but delivers a long-lasting impact on your home’s comfort, performance, and efficiency—particularly during NJ’ hot summers and cool winters.

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 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.
Seal all openings between conditioned and unconditioned areas, including basements, attics, and crawl spaces.
Many local municipalities issue code compliance checklists — the Philadelphia example is available here.
At Local Energy Audits, we utilize thermal imaging equipment, caulk, and spray foam to identify and fix air leaks during testing./li>
Over 90% of our projects pass within two hours, with all required paperwork issued immediately to close the permit.

Preparing for a Blower Door Test in Palisades Park, NJ

For blower door test in Palisades Park, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. 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. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. 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. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Palisades Park, NJ.
