What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. Excessive air changes can also lead to drafts and discomfort caused by air leaks, along with moisture, condensation, and mold problems inside the home. A blower door test in South Orange Village, 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?

In preparation for blower door test in South Orange Village, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal 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 South Orange Village, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. Passing this threshold during your blower door test in South Orange Village, NJ ensures both energy savings and full compliance with local regulations.

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.
Close any gaps connecting conditioned and unconditioned spaces, such as those leading to basements, attics, or crawl spaces.
Local authorities often publish checklists to confirm compliance — get the Philadelphia example here.
Our professionals at Local Energy Audits use caulk, spray foam, and thermal imaging to detect and seal leaks on-site for better efficiency./li>

Preparing for a Blower Door Test in South Orange Village, NJ

Preparation for blower door test in South Orange Village, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve 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 infiltration from outdoors increases, allowing faster and more accurate leak detection. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. 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. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in South Orange Village, NJ.
