What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Southampton, 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?

To carry out blower door test in Southampton, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight 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.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

What Is A Passing Blower Door Test Score?

Construction in Southampton, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized 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 this target in your blower door test in Southampton, NJ helps maintain lower energy bills and fulfills local code obligations.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Close gaps and penetrations between conditioned zones and unconditioned sections like attics, basements, and crawl spaces.

Preparing for a Blower Door Test in Southampton, NJ

Before conducting blower door test in Southampton, NJ, we make sure all heating, cooling, and ventilation fans are switched off. We then perform a detailed walkthrough to verify that all exterior windows and doors are tightly shut, including any that lead to spaces beyond the thermal envelope. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Southampton, NJ building codes.
