Blower Door Test in South Amboy, NJ

Verify your home’s airtightness and meet energy-efficiency standards with a professional blower door test in South Amboy, NJ. Our professional technicians help homeowners, builders, and contractors identify air leaks, improve home comfort, and satisfy NJ energy code regulations.

What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in South Amboy, 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 complete blower door test in South Amboy, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. 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 removes air, outside air naturally flows inside through leaks, joints, and other gaps. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

What Is A Passing Blower Door Test Score?

In South Amboy, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. Passing this requirement during a blower door test in South Amboy, NJ keeps your home efficient and aligned with local building code standards.

Why Do I Need A Blower Door Test?

The State of NJ and its local governments follow the IECC standards, which require blower door test on newly built or remodeled residential dwellings. We routinely help home builders, contractors, and homeowners requiring blower door test in South Amboy, NJ for energy code compliance and permit closure. In some cases, a duct leakage test is needed if ducts or HVAC systems lie outside the home’s thermal envelope. Learn more about energy code compliance.

With blower door test in South Amboy, NJ, homeowners can pinpoint hidden air leaks. The depressurization process makes them obvious, enabling better sealing and lower energy costs. 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.
Use materials like Tyvek or Zip Sheathing as your air barrier and ensure every seam is well taped for best results.
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 code offices often issue compliance checklists — access the Philadelphia example here for reference.
Using thermal imaging technology along with caulk and spray foam, Local Energy Audits identifies and seals leaks during the inspection./li>
We achieve a passing score within two hours in more than 90% of tests and issue the documents to close the building permit.

Preparing for a Blower Door Test in South Amboy, NJ

When preparing for blower door test in South Amboy, NJ, we first switch off the home’s heating, cooling, and exhaust systems. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond the thermal envelope. Once everything is sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. 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. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors 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 South Amboy, NJ.
