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. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Glassboro borough, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Glassboro borough, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in NJ.

What Is A Passing Blower Door Test Score?

In Glassboro borough, NJ, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Complying with this benchmark during a blower door test in Glassboro borough, NJ helps cut energy expenses and meet local building regulations.

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. Our team regularly helps home builders, contractors, and homeowners seeking blower door test in Glassboro borough, NJ to satisfy energy code standards and close final inspections. You might also need a duct leakage test if HVAC systems or ducts are positioned outside the property’s thermal envelope. Learn more about energy code compliance.

Homeowners gain major advantages from blower door test in Glassboro borough, NJ. As the fan depressurizes the home, incoming air through leaks becomes easier to detect, revealing problem spots and potential energy-saving improvements. 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 high-quality air barrier materials like Tyvek or Zip Sheathing and confirm all seams are perfectly taped.
Ensure insulation with the specified R-value is properly installed and fitted throughout 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 cracks and openings between conditioned interiors and unconditioned areas such as crawl spaces, attics, and basements.
Building departments in many areas share checklists for verifying compliance — download the Philadelphia version here as a sample.
Local Energy Audits uses thermal imaging tools, caulk, and spray foam to detect and seal leaks directly on-site./li>
In most situations—over 90% of the time—we get a passing score within two hours and finalize all required paperwork.

Preparing for a Blower Door Test in Glassboro borough, NJ

Preparation for blower door test in Glassboro borough, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces outside the thermal envelope. After ensuring the home is airtight, we install the blower door frame and fan in a central exterior door and depressurize the house to 50 Pascals to record airflow and leakage data accurately. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. 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 Glassboro borough, NJ.

Blower Door Test for Contractors in Glassboro borough, NJ

For contractors conducting blower door test in Glassboro borough, NJ, well-insulated homes generally require only minimal on-site corrections during the test.
