What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. When there are too many air leaks, drafts and discomfort can occur, along with moisture problems such as mold and condensation. A blower door test in Lumberton township, 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 perform blower door test in Lumberton township, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

What Is A Passing Blower Door Test Score?

In Lumberton township, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. Generally, a blower door test result of 3 air changes per hour or less is considered acceptable, ensuring proper energy performance. Meeting this benchmark in your blower door test in Lumberton township, NJ reduces ongoing energy costs while ensuring local regulatory compliance.

Preparing for a Blower Door Test in Lumberton township, NJ

To get ready for blower door test in Lumberton township, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve 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. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Lumberton township, NJ energy standards.
