What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. 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. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Harrison town, NJ assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Harrison town, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. 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?

Construction in Harrison town, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. An acceptable blower door test result in most areas is 3 air changes per hour or less, demonstrating solid energy performance. Reaching the target during your blower door test in Harrison town, NJ guarantees lower energy consumption and full code compliance.

Why Do I Need A Blower Door Test?

Employ an appropriate air barrier system such as Tyvek or Zip Sheathing and verify that each seam has been correctly taped.
Use insulation of the correct R-value and confirm that it’s tightly installed throughout every section of 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.
Seal off any access points or gaps between conditioned and unconditioned spaces like attics, crawl spaces, and basements.

Preparing for a Blower Door Test in Harrison town, NJ

To get ready for blower door test in Harrison town, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements 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. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Harrison town, NJ.
