What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Allendale, NJ detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Allendale, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. 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 air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

In Allendale, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency.
