What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Midland Park, NJ allows early detection of air leaks, helping homeowners and builders boost efficiency and maintain a comfortable, durable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Midland Park, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Midland Park, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. In most areas, an acceptable blower door test result is 3 air changes per hour or less, confirming that the home achieves optimal energy efficiency. Complying with this benchmark during a blower door test in Midland Park, NJ helps cut energy expenses and meet local building regulations.

Preparing for a Blower Door Test in Midland Park, NJ

Getting ready for blower door test in Midland Park, NJ involves turning off all heating, cooling, and exhaust ventilation systems. 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. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected 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. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Midland Park, NJ building codes.
