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. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Mount Olive, NJ helps uncover these issues early, enabling homeowners and builders to detect air leaks, enhance energy efficiency, and ensure a more comfortable, long-lasting home.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Mount Olive, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under NJ conditions.

What Is A Passing Blower Door Test Score?

Construction in Mount Olive, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. 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 Mount Olive, NJ promotes energy savings and demonstrates adherence to local building rules.

Why Do I Need A Blower Door Test?

Both NJ and local jurisdictions adopt the IECC energy code, making blower door test mandatory for new and renovated residential structures. We often collaborate with home builders, contractors, and homeowners who require blower door test in Mount Olive, NJ to meet energy efficiency standards and close permits.

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 every transition point between conditioned and unconditioned environments, including attics, crawl spaces, and basements.

Preparing for a Blower Door Test in Mount Olive, NJ

To properly prepare for blower door test in Mount Olive, NJ, the HVAC system and all bathroom and kitchen fans are turned off. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond the thermal envelope. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting 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 Mount Olive, NJ.

Blower Door Test for Contractors in Mount Olive, NJ

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