What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. 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 Harvey Cedars borough, NJ enables early identification of air leaks, helping improve comfort, durability, and energy savings.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Harvey Cedars borough, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. 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.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. 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 Harvey Cedars borough, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Achieving this goal during your blower door test in Harvey Cedars borough, NJ promotes energy savings and demonstrates adherence to local building rules.

Preparing for a Blower Door Test in Harvey Cedars borough, NJ

We begin blower door test in Harvey Cedars borough, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond the thermal envelope. Once everything is sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. 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 the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Harvey Cedars borough, NJ energy code requirements.

Blower Door Test for Contractors in Harvey Cedars borough, NJ

For contractors arranging blower door test in Harvey Cedars borough, NJ, most homes with professional insulation can handle small air leakage issues during the test itself.
