What Is A Blower Door Test?

A blower door test is performed to identify the rate of air changes per hour, confirming your home receives a healthy exchange of fresh air. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. 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 Longport borough, NJ identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Longport borough, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. 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.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.

What Is A Passing Blower Door Test Score?

Homes throughout Longport borough, NJ are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Complying with this benchmark during a blower door test in Longport borough, NJ helps cut energy expenses and meet local building regulations.

Apply insulation of the correct R-value and make sure it fits snugly in all areas 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 gaps and openings separating conditioned spaces from unconditioned areas, including crawl spaces, basements, and attics.

Preparing for a Blower Door Test in Longport borough, NJ

We begin blower door test in Longport borough, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. 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. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. We carry chalk, spray foam, and weatherstripping materials, allowing us to work directly with homeowners or contractors to fix visible air leakage issues on-site. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Longport borough, NJ.
