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. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Excessive air changes often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in Palmyra, NJ enables early identification of air leaks, helping improve comfort, durability, and energy savings.

What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Palmyra, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

What Is A Passing Blower Door Test Score?

Homes in Palmyra, NJ are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Reaching this target in your blower door test in Palmyra, NJ helps maintain lower energy bills and fulfills local code obligations.

Preparing for a Blower Door Test in Palmyra, NJ

Preparation for blower door test in Palmyra, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. 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. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Palmyra, NJ.
