What Is A Blower Door Test?

A blower door test measures how many air changes per hour occur in your home, ensuring fresh air circulation and improved indoor air quality. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Metuchen, NJ helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Metuchen, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. 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 Metuchen, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. An acceptable blower door test result in most areas is 3 air changes per hour or less, demonstrating solid energy performance. Achieving compliance in your blower door test in Metuchen, NJ helps improve energy efficiency and meet all local code mandates.

Preparing for a Blower Door Test in Metuchen, NJ

Before conducting blower door test in Metuchen, NJ, we make sure all heating, cooling, and ventilation fans are switched off. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, 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. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Metuchen, NJ efficiency codes.
