What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Roselle Park, NJ helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Roselle Park, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

What Is A Passing Blower Door Test Score?

In Roselle Park, 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. Reaching the target during your blower door test in Roselle Park, NJ guarantees lower energy consumption and full code compliance.

Why Do I Need A Blower Door Test?

Homeowners gain major advantages from blower door test in Roselle Park, NJ. As the fan depressurizes the home, incoming air through leaks becomes easier to detect, revealing problem spots and potential energy-saving improvements. Typically completed within a few hours, a blower door test provides a long-lasting impact on comfort, energy efficiency, and overall home performance in NJ’ varied climate.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Use a reliable air barrier like Tyvek or Zip Sheathing and make sure all seams are securely taped.
Install insulation that meets the required R-value and check that it’s evenly and securely placed throughout 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 complete sealing of all openings between conditioned rooms and unconditioned areas like basements, attics, and crawl spaces.
Local building authorities commonly offer checklists to verify code compliance — review the Philadelphia example here.
Local Energy Audits arrives fully equipped with thermal imaging, caulk, and spray foam to detect and seal leaks in one visit./li>

Preparing for a Blower Door Test in Roselle Park, NJ

We start the process of blower door test in Roselle Park, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining the thermal envelope. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. 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. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Roselle Park, NJ.
