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. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Excessive air changes often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in Bass River township, NJ helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Bass River township, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Bass River township, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. In most jurisdictions, 3 air changes per hour or less is the benchmark for acceptable blower door test results and energy efficiency. Meeting this requirement during your blower door test in Bass River township, NJ helps reduce energy costs while keeping your home compliant with local building codes.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Select a proper air barrier such as Tyvek or Zip Sheathing and ensure every seam is thoroughly taped for airtight sealing.
Place insulation with the accurate R-value and check for proper installation and full coverage in 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.
Close any gaps connecting conditioned and unconditioned spaces, such as those leading to basements, attics, or crawl spaces.
Local permitting offices often offer official compliance checklists — review the Philadelphia sample here for reference.
Local Energy Audits uses professional-grade thermal imaging, caulk, and spray foam to locate and close leaks during the visit./li>

Preparing for a Blower Door Test in Bass River township, NJ

We start the process of blower door test in Bass River township, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. 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 the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. We carry chalk, spray foam, and weatherstripping materials, allowing us to work directly with homeowners or contractors to fix visible air leakage issues on-site. 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 Bass River township, NJ.
