Blower Door Test in West Windsor, NJ

Ensure your home is sealed properly and energy-efficient with quality blower door test in West Windsor, NJ. Our certified team helps homeowners, builders, and contractors locate air leaks, enhance indoor comfort, and meet all NJ energy efficiency requirements.

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. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in West Windsor, 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?

When blower door test in West Windsor, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior 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?

Homes throughout West Windsor, NJ are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Achieving this standard in your blower door test in West Windsor, NJ lowers utility bills and guarantees adherence to local code requirements.

Preparing for a Blower Door Test in West Windsor, NJ

Preparation for blower door test in West Windsor, 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. 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. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in West Windsor, NJ.
