What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. Excessive air changes can also lead to drafts and discomfort caused by air leaks, along with moisture, condensation, and mold problems inside the home. A blower door test in Stafford township, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Stafford township, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. 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?

Construction in Stafford township, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. Achieving compliance in your blower door test in Stafford township, NJ helps improve energy efficiency and meet all local code mandates.

Preparing for a Blower Door Test in Stafford township, NJ

When preparing for blower door test in Stafford township, NJ, we first switch off the home’s heating, cooling, and exhaust systems. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area outside the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Stafford township, NJ.
