What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. Too many air changes, however, can be detrimental because every time the air is replaced, it must be reheated or recooled, leading to higher energy use and lower efficiency. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in Long Beach, 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 perform blower door test in Long Beach, 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. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. 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?

In Long Beach, NJ, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. In most jurisdictions, 3 air changes per hour or less is the benchmark for acceptable blower door test results and energy efficiency. Passing this requirement during a blower door test in Long Beach, NJ keeps your home efficient and aligned with local building code standards.

Why Do I Need A Blower Door Test?

The State of NJ, along with its municipalities, observes the IECC requirements, mandating blower door test for newly constructed or updated homes.

Homeowners gain major advantages from blower door test in Long Beach, NJ. As the fan depressurizes the home, incoming air through leaks becomes easier to detect, revealing problem spots and potential energy-saving improvements. Though a blower door test lasts just a few hours, it offers a long-lasting impact on your home’s comfort, durability, and performance year-round in NJ.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Choose Tyvek or Zip Sheathing as your air barrier and check that all seams are securely taped to maintain airtightness.
Fit insulation with the correct R-value and make sure it’s installed without voids across the entire 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 the transitions between conditioned and unconditioned zones, particularly around basements, attics, and crawl spaces.
Local permitting offices often offer official compliance checklists — review the Philadelphia sample here for reference.
Local Energy Audits is equipped with thermal imaging tools, caulk, and spray foam to find and seal air leaks immediately on-site./li>

Preparing for a Blower Door Test in Long Beach, NJ

To prepare a home for blower door test in Long Beach, NJ, we shut off the HVAC system and disable all exhaust fans. We follow with a quick walkthrough to ensure all exterior doors and windows are fully closed — including those that connect to garages, basements, or any part outside the thermal envelope. Once preparation is complete, the blower door fan and frame are installed in a centrally located exterior door. The fan then reduces pressure to 50 Pascals, allowing accurate leakage assessment. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. Once sealing is complete, we perform an immediate retest to verify that the desired blower door score is achieved and that your home meets all energy efficiency requirements in Long Beach, NJ.
